The 25th Anniversary of the Buell Motorcycle Company coincides with a new chapter in the history of America’s largest manufacturer of sporting motorcycles: A liquid cooled 72-degree 1125cc motor powering its all new 2008 Buell 1125R.
At the heart of the 1125R is the Helicon V-Twin powerplant, claimed to produce 146 horsepower at the crank, developed in conjunction with BRP-Rotax specifically for Buell and the 1125R. Buell fans can rest assured that the bike is true to the Buell heritage of being rider friendly and decidedly different than the competition. The fuel-in-the-frame technology is retained, although capacity has been raised to 5.6 gallons. It’s still-stubby 54.5-inch wheelbase is 2.5-inches longer than the current Firebolt design and should still be plenty agile. The next generation of the Zero Torsion Load single-disc front braking system, ZTL2, features an 8-piston caliper derived from the XBRR racing platform and should provide plenty of power to haul this beast down from speed.
After years of riding and enjoying Buell motorcycles, the primary complaint from this company and the majority of the motorcycle media was a decided lack of power compared to the competition. Buell appears to have addressed this issue and with the track introduction of this new bike just weeks away, the answer to some of the questions on the minds of consumers everywhere will soon be answered.
Will the bike be as powerful as Buell claims? Will it still have that razor-sharp handling of its predecessors? Will the chassis be stable enough to handle the additional speed facilitated by the new motor? How will this version perform on the race track? How will it stack up to the other V-Twin liter bikes? We should have answers to all of these except the last question by the end of August.

Stunt bike show @ Darius Kashabi.
An amazing clip with some really cool moto stunts show. Real Skill only! Xtreme compilation of Extreme Sports.
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.
NO clutch, NO Frontend, NO BRAKES… NO PROBLEM. Do NOT try this at HOME!
Crazy moto tricks and cops together. 
Great video, must to see…
