2012 MV Agusta F4 R

Italian brand Mv Agusta has released the official photos of the new F4 R. The key feature of the F4 R is, in fact, the new “Corsa Corta” engine capable of extraordinary performance and already employed on the F4 RR, the top of the MV Agusta superbike range. The new 4 cylinder inline with radial valves is the pulsing heart of the MV Agusta F4 R. The thermodynamics have been completely redesigned, starting from the new low inertia crankshaft which makes it possible to use a super over-square bore and stroke ratio.


In this way, the MV F4 R is capable of reaching rpm worthy of a pure racing motorcycle. The engine capacity of 998cc has been obtained by using a bore of 79 mm and a stroke of only 50.9 mm. The new engine of the MV Agusta F4 R was designed with the scope of reducing the internal friction to a minimum: the transmission’s new primary gear ratio allowed a drastic reduction in rpm of both generator and water pump, thereby limiting the absorbed power. This extraordinary engine utilizes the unique features that have become trademarks to MV Agusta including a removable 6-speed gearbox and a slipper clutch which assures precise control even during the most violent braking manoeuvres. The electronic management system has been continuously evolved, the traction control employs a new algorithm and maintains the two rider selectable engine maps, all of which are now comfortably adjustable by means of the new control situated on the left handlebar.

The new F4 R, already on sale at official dealers, is available in 2 colours: red/grey and white/medium grey, at a price of 18800 € including tax in Italy (Every country could have a price variation due to local import duties and taxes).

2012 - Ducati 848 Streetfighter

With the world launch of the 1199 Panigale superbike at the EICMA show in Milan still a month away, Ducati filled the interim with an international press launch of the 2012 848 Streetfighter. The combined street and track ride in and around Modena, Italy, exposed the newest naked performer to Sunday morning twisties and trackday duties.
Nearly identical in appearance to the larger 1098 Streetfighter, the new 848 is meant to provide motorcyclists a more affordable and less extreme option to the superbike-powered S model, which is the only other Streetfighter available for 2012 as the standard Streetfighter is being discontinued.

The most obvious difference between the two 2012 Streetfighter models is engine displacement. Whereas the Streetfighter S utilizes Ducati’s 1099cc L-Twin cylinder engine producing a claimed 155 hp and 89 ft.-lb. of torque at 9500 rpm, the new Fighter is powered by an 848cc Twin outputing a claimed 132 hp and 69 ft.-lb. of torque at 10,000 and 9500 rpm, respectively. Producing its peak horsepower 500 rpm higher in the rev range and with a compression ratio of 13.2:1, compared to the S’s 12.5:1, the new SF is a little more high-strung than the larger-displacement model.



Ducati’s crankshaft-derived power figures will decrease when run on a rear-wheel dyno. The 848 Superbike is factory-rated at 140 hp, 8 up from the new Streetfighter due to slightly less valve lift and duration, and it produced 119 hp on the Superflow dyno at Mickey Cohen Motorsports during our middleweight sportbike shootout. Thus, we expect the 848 SF to generate a little over 110 ponies at the rear wheel.

This amount of power is plenty fun and exciting on a bike weighing approximately 410 pounds full of fluids. On the street there’s enough oomph for any situation, whether it be wheelieing or passing, while on the track the 848 Fighter will make easy work of better bikes with lesser riders.

Set to retail at $13,000, the 848 Streetfighter is substantially more affordable than the $19,000 Streetfighter S but only $2000 less than the soon to be nonexistent $15,000 standard Streetfighter (hurry and get yours now if you perceive the standard 2011 1098 Streetfighter a better value). The 848 does retain Ducati Traction Control, which is a commendable technology to be included at such a low MSRP.

The bigger Streetfighter S model, in addition to the increased power of the larger engine, boasts an Ohlins fork whereas the 848’s front legs are of the Marzocchi variety. Both suspension components are fully adjustable and measure 43mm in diameter. The 848’s front end, however, is steeper than the S with 24.5 degrees of rake compared to 25.6 degrees on the S model. The 848 also has less trail than the S, 103mm vs 114mm, respectively, but the wheelbase of both bikes remains identical at 58.1 inches.

Whether on the street or the track the Streetfighter takes some time for the bike to feel comfortable and/or familiar. The front end on the 848 version as well as the 1099cc original can feel a bit twitchy, especially when leaned into a corner, and trail braking doesn’t come naturally when riding the Streetfighter. With the 848 spanning the same distance between contact patches as the S model but with a steeper rake and less trail suggests that Ducati may still be searching for a better base setup — which if achieved would go a long way in making the bike more inviting — but neither measurement lends itself to improved confidence.



Usually less rake and more trail would help calm down a nervous front end, so Ducati’s unconventional approach of more rake and less trail to apply calm is interesting. Without a 1098 Streetfighter to ride for comparative purposes at the event, it’s hard to say if the change in front end measurements are better or worse, with the issue still persisting, though, it’s definitely not solved.
It wasn’t until the second session on the track that I was riding comfortably fast, pushing the Streetfighter closer to the edge of its performance envelope. The front end’s nervousness and higher handlebars dictate a light touch — ham-fistedness results in a wondering front wheel.

Other significant differences of the 848 SF include a wet rather than dry clutch and new 10-spoke wheels instead of the five-spokers on the S. The tapered aluminum handlebars of the 848 are also 20mm higher than those of the S model. The high seat height of the S, 33 inches, carries over to the new 848, as do the slippery footpegs.
The majority of these changes comprise to make the new 848 Streetfighter a better companion to the motorcyclist who is more concerned with the competency of the Streetfighter as a usable streetbike and less about the upgraded performance of the S model.


The higher handlebars, for instance, relieve some of the pressure on a rider’s wrists allowing for more time spent in the saddle. Because Ducati didn’t go as far as to change the seating position itself, this extra leverage is oftentimes put to use maintaining a comfortable distance between fuel tank and crotch. The combination of a very narrow tank/seat junction and downward sloping seat can make bumpy road riding a testicle-harrowing experience.





On a smooth, closed course racetrack such as the brand new Autodromo Modena (the 848 Streetfighter press intro was the track’s first official function) the narrow seat/tank juncture allows for quick, side-to-side transitioning.

Complaints were made of the original Streetfighter that a rider’s right ankle was forced uncomfortably away from the bike due to an exhaust heat guard. Ducati addressed this on the 2012 848 SF by adding a 10mm spacer to the right footpeg. Yes, the ankle no longer feels at an odd angle, but the modification did take away a degree of lean angle on a bike that has riders touching toe sliders to tarmac in concert with placing a knee on the ground.

The twin front, radially-mounted Brembo brakes and 320mm discs provide good braking power and didn’t fade during our two track sessions, but feel at the adjustable lever is a little vague.



At the rear of the bike a fully adjustable Sachs shock attaches to a cast aluminum single-sided swingarm. The 5.5-inch rim holds a new 180/60 ZR17 Pirelli Diablo Corsa tire. The new size tire provides a wider contact area over its radius, and Pirelli claims improved damping capabilities to provide a smoother ride. Boasting a World Superbike compound on the right and left sides, the tire’s traction was never in question.


The 848 Streetfighter will be available in Fighter Yellow, Ducati Red and Dark Stealth but in any color the bike remains a stunner. The aggressive sex appeal of this motorcycle is undeniable, and if you can manage its few foibles, the 848 Streetfighter should make for a wonderful companion.


With the exception of the uncomfortable tank/seat juncture, the seating position provides plenty of leg room and a respectable distance from seat to footpegs. The higher handlebars will help keep the weight of a passenger off the rider’s back and the increased distance of the footpeg alleviates discomfort of the rider’s right foot.




I personally wouldn’t want to spend more than an afternoon on the Streetfighter, but for a motorcyclist looking for competent weekend carver and occasional track day tool the Streetfighter is all that in an attention-getting package.

2012 - Suzuki GSX-R 1000 introduced

Once again, the best keeps getting better. Introducing the new 2012 Suzuki GSX-R1000. Suzuki engineers have thoroughly redesigned the engine, chassis, suspension, and bodywork to create a supersport bike that is more dominant than ever. With refinements ranging from a new titanium 4-2-1 exhaust system to completely redesigned pistons, the engine rewards you with quicker acceleration, crisper throttle response and improved fuel efficiency. The chassis, suspension and braking systems are also refined for enhanced performance and a reduction in weight of over four pounds.



* Thanks to Suzuki’s uncompromising efforts to shave excess weight, the 2012 GSX-R1000 is 2kg lighter than its predecessor.

* The 4-2-1 exhaust system, carrying a Suzuki Exhaust Tuning (SET) valve maximizing torque and improving throttle response, particularly in the low-to-mid rpm range. Less weight at the back of the bike means better mass-centralization, which turns into better handling performance.

* Lighter, more durable forged pistons designed with the same Finite Element Method (FEM) and fatigue analysis technology used for MotoGP racing engines, and consequently the pistons are 11% lighter.

* New pentagonal shaped ventilation holes (instead of rectangular shape in previous model) in the sides of each cylinder bore reduce pumping losses due to internal crankcase air-pressure resistance to downward piston movement.

* Optimised camshaft profiles for great racing potential, developed using proven MotoGP racing engine technology.

* Optimally-shaped combustion chambers and an increased compression ratio of 12.9:1 (up from 12.8:1) promote low-range and mid-range performance and help to realise a broad torque curve.

* Thinner material for the tappet skirts means a weight saving of 2.5 grams per tappet. The reduced inertial mass gave Suzuki the freedom to optimise the valve lift curve.

* An engine control module (ECM) provides state-of-the-art engine management and has optimised settings to suit the single muffler which results in better fuel economy and linear throttle response.

* The front disk brakes are equipped with the top-of-the-line radial-mount Brembo Monoblock callipers and lighter Sunstar Engineering front discs.

* Big Piston Front forks (BPF) with an endurance-race-proven design deliver superior feedback and responsive, stable operation and are lightweight. For 2012, suspension settings are refined for the bike’s lower weight and the shift in centre of gravity.

* The lightweight and high-grip front and rear tyres reduce unsprung weight for sharp handling.

* Attention to rider comfort includes a carefully-shaped seat with new high-grip leather for better holding feel.

* The wheels have red pin stripes punctuated by “R” logos that highlight the bike’s identity.
The bike’s identity is emphasised by bigger “GSX-R” graphics and more extensive use of Suzuki’s signature blue colour on the bodywork.

* 999cm3 4-cylinder engine with Bore x Stroke of 74.5mm x 57.3mm brings enhanced throttle response across the entire rpm range and high potential for racetrack performance.
The compact engine enabled short wheelbase and 32mm long swingarm at the same time to improve racetrack performance.

* Suzuki Composite Electrochemical Material (SCEM)-plated cylinders integrated into the upper crankcase, reduce friction and improving heat transfer, durability and ring seal.



* 12-hole fuel injectors produce a fine fuel mist for more complete combustion, reducing fuel consumption and exhaust emissions.

2012 Kawasaki Street Models Updates

It’s a year of significant updates for four existing Kawasaki models. The headlining news is the ZX-14R mega-sportbike, using a bigger, more powerful engine and receiving hundreds of other revisions to finally leave Suzuki’s Hayabusa in the rearview mirror. So much was changed it deserved its own 
But Kawasaki’s R&D department has been busy upgrading other streetbikes in its lineup, including a significantly updated Ninja 650, ABS added as an option on the Ninja 1000, and the Vulcan 1700 Voyager is equipped with an innovative heat-management system.




2012 Ninja 650
Like the new ZX-14R announced today, the 2012 Ninja 650 celebrates six years as part of Kawasaki’s street lineup. And also like the big Ninja, the 650 gets significantly updated for 2012.




2012 Kawasaki Ninja 650
The sporty but fuel-conscious 649cc parallel-Twin powering this middleweight Ninja streetbike sees updates in the exhaust system, including a new header-section connector pipe and a three-chamber muffler design. This new exhaust is a key contributor to improved gains in mid-range power according to Kawi.

Holding the engine is an all-new twin-pipe perimeter frame – nearly 2 inches (50mm) narrower in the knee/footpeg area – and is joined by a cool, new twin-pipe swingarm.


New twin-tube style swingarm is prominently displayed; it creates a less-cluttered look and better matches the lines of the new frame. A new footpeg hanger is also well-integrated visually.

All-new instrument panel includes an analog tachometer, which should prove much easer to read than the digital tach on the previous 650’s all-LCD gauge cluster. The Ninja 650 also gets a new, 3-position windscreen.
Both are said to provide increased rigidity over the previous 650’s frame. A new backbone-type subframe also offers a 10% increase in maximum carrying capacity. Rake and wheelbase remains the same as last year, while trail sees a nominal increase from 4.2 to 4.3 inches.

Revised suspension settings, including a 0.2-inch increase in travel front and rear (4.9” front, 5.1” rear), are apparently aimed at improved rider comfort. Although Kawasaki doesn’t specify as to the suspension updates other than the moderate increase in travel, we speculate minor internal changes for improved damping performance.

Effort at the clutch was reduced, new brake pad materials promise a slight increase in braking power, and Dunlop’s new Roadsmart II tires are now standard.



Rider ergos see comfort improvements in the form of a 20mm wider handlebar and a two-piece seat assembly with foam that’s wider and thicker. Seat foam thickness likely accounts for the 0.6-inch increase from last year’s seat height that’s now at 31.7 inches. Both the handlebar and saddle are rubber-mounted, along with the footpegs, to help mitigate vibration from the inherently buzzy vertical-Twin engine design.

A new instrument panel features an analog tachometer situated above an LCD info-panel showing speed, trip meters, fuel consumption, remaining range, etc., and the ignition is now located at the fuel tank assembly in order to give a clear view of the gauge cluster.

Bodywork was updated for better aerodynamics and improved engine-heat dissipation, while styling was influenced by the ZX-14R’s appearance. The manually adjusted, three-position windscreen we like so much on the 2011 Ninja 1000 was apparently a big hit elsewhere, as the 2012 Ninja 650 now also sports a three-position shield. However, unlike the Ninja 1000’s simple hand-operated, tool-less shield adjustment, the Ninja 650’s shield requires the use of tools to alter positions.

Fuel capacity of 4.2 gallons is up 0.1-gallon from last year, and battery size was decreased. Also up is curb weight, going from just under 450 pounds in 2011 to a little less than 461 pounds on the ’12 model.



The 2012 Ninja 650 comes in Metallic Spark Black, Candy Lime Green or Passion Red, and has an MSRP of $7499.

2012 - Yamaha YZF-R15

Small-displacement sportbikes are getting more attention as the world economy continues to struggle. The 150cc Yamaha YZF-R15 was the first sportbike produced in India back in 2008, and the fuel-injected model now receives a host of upgrades and is offered to the Australian, New Zealand and Colombian markets. Read the below review and let us know if such a small sportbike could be successful in North America.

Yamaha’s YZF-R15 has offered riders the ultimate sportbike in its 150cc segment, managing to retain the unadulterated feel of its legendary mentors, the supersports YZF-R6 and R1.

Leaned over mid-corner, tires fiercely gripping the tarmac, its engine screaming out the high revs it craves, this Yamaha has treated aspiring sportbike riders ever since its launch. The lean and compact, technology-packed R15 represents a mean package, accelerating, turning and stopping with the aggression of a precision, laser-guided missile.







Powering around a set of corners at the Madras Motorsports track,  India, the YZF-R15 Version 2.0 feels every bit as good as Yamaha’s “Racing Instinct” philosophy suggests. Just how much better is the R15 V2.0, and can it reignite the passion amongst sport bikers as did the original?


The list of changes is extensive. Although the aggressive twin-headlights remain familiar, there’s a beefier mid-fairing region, now with slotted vents that Yamaha claim improve the motorcycle’s aerodynamic efficiency by 4 percent. A stylish new mock carbon fiber panel looks a part of the frame, while V 2.0 also boasts an extensively altered, steeply angled and waspish looking split-seat.




Among the many changes for 2012 is an R6-inspired LED tail-lamp.


At the rear you spot a higher, YZF-R6 inspired LED tail-lamp. Below this sits a smartly machined, alloy number plate and turn indicator mount. The exhaust is far better looking, more aggressively angled and you can’t miss the elaborate new rear wheel hugger which doesn’t really fit in well on a sportbike like this.


Look closer and finer changes are apparent; the still compact R15 looking longer than its predecessor, as its wheelbase has extended 55mm (nearly 2 inches), thanks to a new alloy swingarm, rare for this class of motorcycle. A larger 130/70 section radial rear tire completes the muscular looking rear. The front disc brake enjoys a larger carrier, while the rear disc is now slightly bigger at 220mm.


The ECU has modified tuning for improved throttle response, and the throttle operating cam is shaped for more linear response. Yamaha has sadly failed to add power to the new model, and enthusiasts are sure to feel let down when noticing the unchanged 16.8 hp at 8500 rpm peak power output. What’s more, the V2.0 tips the scales at 5kg (11 lbs) more than the original R15. It now claims a 300-pound curb weight.






Sling a leg over the YZF-R15 V2.0, and you immediately understand how the riding position is so much more track focused, with its relatively forward-set stance. A light, unobtrusive buzz from the 150cc, liquid-cooled, single-cylinder powerplant is familiar as I make my way around the track on a cautious initial lap.


What’s immediately apparent is how the power deliver has improved. Unlike earlier R15’s that had to be wound up to really get going, the V2.0 is clearly more responsive, with a healthier punch in the bottom and mid-range of its powerband. The bike revs cleanly to its 10,000-rpm limiter. This more user-friendly nature vastly improves the R15’s public road abilities, which was a sore point on the earlier motorcycle. As speeds increase, it’s clear that fears of any significant drop in performance are unfounded. Pleasantly, our tests confirm the new Yamaha as faster, the V2.0 achieving 100 kph (62.5 mph) from standstill half a second quicker than managed by us on the older motorcycle, in 14.14 seconds.


Yamaha’s steel Deltabox frame is the magic wand that grants the R15 rock-solid poise around corners, and an almost feline-like affinity for quick direction changes. It’s a case of the best getting better, the longer alloy swingarm and improved tires significantly improving stability. A big change is palpable when attacking corners, with some negligible sacrifice to flickability, but a newfound stability there for the asking in a corner. The R15 V2.0 is more forgiving, and prods you to ride harder and faster. The sportier riding position and heavier front weight bias provide a more connected, direct feel, which experienced riders will exploit to extract better pace.



The revised, Indian-made MRF tires provide solid grip when leaned over or under hard braking. We found nothing but absolute commitment even when expecting rear wheel hop while pushing hard over patchy, bumpy tarmac. The bite from the front brake is hard to fault, always powerful enough, while still progressive.






Street riders have dealt with the R15’s shortcomings before, and so have only about as much to complain about, with the bonus of improved power delivery attempting to make up in some measure for the uncomfortable riding position.
Paying more for this upgraded model despite no peak power gains are might seem to hold back this revised model, and the R15’s brilliant chassis truly begs for more power to match its perfectly sorted dynamics. The competition is only intensifying with every passing day, which means Yamaha still need to pull their gloves off a little further, with even more conviction.
