The guys at the Aprilia Forum have gotten word that the 2011 Aprilia RSV4 will get an 8hp power increase, bringing the 999cc V4 motor to a total claimed output of 186hp. Also as expected by us back in June, the 2011 Aprilia RSV4 will see the introduction of Aprilia’s traction control system (ATC). The 2011 Aprilia RSV4 will make its extra horsepower by raising the cylinder compression ratio via high compression pistons, and using a different timing chains. Other changes include a different exhaust can (smaller), and gearing changes (taller: 1st, 2nd, 3rd, shorter: 4th, 5th, 6th, with a larger 42 tooth rear sprocket).
After getting the nod to use their gear driven camshaft in World Superbike racing (shown above is the Aprilia’s belt driven camshaft), Aprilia has become a tour de force on the WSBK grid. Aprilia first used the gear driven cams in race environment while at the Miller Motorsports Park round, much to the protest of the other teams.
Aprilia and Max Biaggi have been on a bender since the new camshaft’s implementation, with the Aprilia RSV4 going double-double (no, not that Double-Double) and winning every race since the gear driven camshaft was installed on the race bike.
Jorge “Aspar” Martinez has once again been linked with being a part of Aprilia’s alleged entry into MotoGP racing. Reportedly working with Aprilia to develop a 1000cc motor based off the RSV4 Superbike powerplant that’s dominating World Superbike right now, Aspar and Aprilia have denied any intention to go racing together in MotoGP.
For his part, Aspar currently has his hands full racing in all three of the GP series, while Aprilia has voiced that its priority right now is winning in WSBK. The final nail in the coffin for this rumor is its timeframe of a 2011 entry, which barring another rule change from the GP Commission, is still an 800cc rule year.
UPDATE: Aprilia has confirmed that the Aprilia RSV4 Biaggi Replica will not be available for purchase directly in the US, and is bought directly from Aprilia Racing in Italy. The Aprilia RSV4 Biaggi Replica is also upgradeable via Aprilia Racing’s catalog, which means gear-driven cam shafts, Biaggi swingarms, and all the other fun go-fast parts that are “publicly” available to meet WSBK regulations.
Well the rumors were true, as the Aprilia RSV4 Biaggi Replica was launched this weekend at the World Superbike races being held at Monza, Italy. Boasting the goodies found on Max Biaggi’s Aprilia RSV4 race bike, the RSV4 Biaggi Replica has an astounding 200hp motor strapped to its anorexic 175kg (385lbs wet sans fuel) frame. For that level of performance, you can expect some sticker shock, and the Aprilia RSV4 Biaggi Replica is no exception. Owning this true race replica will set you back €50,000, but it’s totally worth it, right? Photos and more after the jump.
It was Suzuki who drew first blood, breaking the 200mph barrier at Monza, but it was Max Biaggi who set the bar the highest today during World Superbike FP1 practice. Clocking 203.21 mph (nearly 327 kph) down the straight, Biaggi broke the WSBK top speed record, but still fell short of the all-time superbike record, which was also set at Monza, and also by an Aprilia.
Last week, Fabrizio Pellizzon clocked 203.4 mph on his CIV spec’d Aprilia RSV4. Either way you look at it, the Alitalia Aprilia team is sure to be a force in Italy this week.
MotoBlog.it is reporting that Aprilia is set to release a race-spec replica of its RSV4 superbike. While the rumor is not clear if this will be a track-only model, or street-legal race rep like the Desmosedici RR, what is clear is that the bike is expected come with a WSBK spec motor, chassis, and electronics package.
With a price tagged rumored to be around €50,000, the race replica RSV4 certainly won’t be cheap if it’s built, but compare that price to the €90,000 price tag that comes on Ducati’s 1198RS race bike that teams have to purchase from Bologna if they want to compete in WSBK, and the RSV4 starts looking very affordable. However, with most rumors, we’re not sure this story is all that it’s cracked up to be. Keep reading for our analysis and thoughts.
World Superbike has clarified its position after teams lodged a complaint against Aprilia for the team’s use of a gear-driven camshaft motor during the practice session at the Phillip Island WSBK stop. Despite the fact that the gear-driven camshaft is a publicly available upgrade to the RSV4 motor, and was not specially outlawed in WSBK regulations, other teams in the paddock threw a fit when they got word that Aprilia was testing the motor while in Australia, and planned to use it in Portimao.
Not wanting to be on the wrongside of the rules, Aprilia refrained from using the technology at Portimao, but it looks like WSBK’s clarification of Rule 2.4.8 would have left the Italian team in the clear, with a caveat.
For the 2010 World Superbike season, Aprilia is looking to build upon their successful 2009 season, which saw Max Biaggi finishing 4th despite the RSV4’s first outing in WSBK racing. While the 2009 factory Aprilia team ran no title sponsorhip, that’s all set to change in 2010 with the announcement that Italian airline Alitalia will be headlining on the teams livery.
Per an announcement by the NHTSA, it’s now been confirmed that the RSV4’s connecting rods were to blame for Aprilia having to recall 335 RSV4 Factory and RSV4 R motorcycles. The rods, which are supplied by an outside supplier, were straightened using a method that compromised their strength and reliability, and were apparently responsible for not only sidelining an RSV4 track event with the press, but also requiring almost all the RSV4’s sold to-date to be brought in for servicing via this recall.
After discovering a faulty component was used in a select number of RSV4 motors, Aprilia is recalling nearly 300 V4 superbike motors worldwide, including ever motor shipped in bikes to the United States. While the faulty component isn’t being named, early rumors peg the bike’s connecting rod bearing, which sidelined the company’s track day debut to the press several months ago, as being the problem piece.
To-date, there have been no known engine failures on customer bikes, but Aprilia isn’t taking any chances, and has motors already on the way from Italy. The company hopes to have the recall finished by February, and will be personally contacting each RSV4 owner. Press statement after the jump.
