The Aprilia RSV4’s 65° V4 motor produces a claimed 180bhp@12,500rpm and 85ftlb@10,000rpm. It has a single block crankcase with integrated cylinder liners, titanium inlet valves and balance shaft. The six-speed cassette gearbox is removable, handy for racing and a slipper clutch comes as standard. Being a V4, the engine is incredibly small and has allowed Aprilia to make a tiny bike around it, but the power delivery is the best part. It’s so smooth and wide the motor doesn’t actually feel that powerful and you don’t realise how fast you’re going, until you look down at the speedo! The engine note is similar to the deep, metallic boom of the RSV twin and the spread of power is actually very reminiscent of the new ‘long bang’ Yamaha R1.
Ride and Handling
We can’t give the RSV4 a perfect score for handling as we only rode it in rain conditions, albeit on racing wets. What is impressive is that the Ohlins forks and shock have the adjustment in them to make the Aprilia soft and plush to suit the conditions, giving masses of feel and confidence to the rider. Monobloc Brembo brakes are powerful, but unlike a Ducati easy to use and not too brutal. Being so compact, the RSV4 is a bit of a squeeze for riders over six-foot.

Harley-Davidson Motor Company is an American manufacturer of motorcycles based in Milwaukee, Wisconsin. The company sells heavyweight (over 750 cc) motorcycles designed for cruising on the highway. Harley-Davidson motorcycles (popularly known as “Harleys”) have a distinctive design and exhaust note. They are especially noted for the tradition of heavy customization that gave rise to the chopper-style of motorcycle.
Harley-Davidson attracts a loyal brand community, with licensing of the Harley-Davidson logo accounting for almost 5% of the company’s net revenue ($41 million in 2004). Harley-Davidson supplies many American police forces with their motorcycle fleets.
In 2003, the Buell Motorcycle Company became a wholly-owned subsidiary of Harley-Davidson, the same year that Harley-Davidson celebrated its 100th birthday. In August 2008, Harley-Davidson purchased the Italian motorcycle manufacturer MV Agusta. Read more…
Yamaha’s YZF-R6 has been a major player in the middleweight sportbike wars ever since it debuted in 1999. Combining light weight with razor-sharp handling and a wailing top-end punch, Yammie’s 600cc screamer has been a potent tool that perennially competes for top honors in its class.
Then in 2006, the R6 received a ground-up overhaul that resulted in a package that many judged to be the tastiest eye-candy in the segment. That (plus an optimistic 17,500-rpm tachometer) garnered plenty of attention among consumers and the media alike. This flash and controversy somewhat overshadowed a stellar chassis and the bike’s less-streetable character from its racy ergos and the engine’s top-heavy powerband.
In the ever changing world of global superbike supremacy, the mantra “evolve or get left behind” still holds true. The 2009 Kawasaki Ninja® ZX™-14 has not rested on its laurels. The winning traits – massive torque, effortless power, agile handling and comfortable ergonomics – of the 1352cc Ninja king have landed it a sizeable collection of open class sportbike victories. Despite ever-tightening noise and emissions regulations; the ZX-14 has continued to set the pace of sportbike excellence ever since its domineering debut in March of 2006.
No doubt about it, the ZX-14 is a testament to effective evolution. Its engine and exhaust system permit it to comply with strict Euro-III emissions and tightening noise regulations. However, the ZX-14’s low-end torque, mid-range surge and its legendary Ninja peak power place it at the top of the sportbike food chain.
Travis Pastrana. Still out of control. Still amazing. A legend of FMX. Possibly his last time running freestyle in competition. This is his winning run at X-Fighters Madrid 2007.
Jawa is a motorcycle manufacturer in the Czech republic, formerly Czechoslovakia. It was named after its founder Janeček bought the motorcycle production of Wanderer in 1929, by concatenating the first letters of Janeček and Wanderer. The company is still active today.
