While the video of MotoCzysz putting their new D1-10 electric motor up on the dyno is not terribly captivating (it’s hard to see anything really moving since all the fun bits are inside the motor’s casings), the performance figures the company quotes surely are impressive. The liquid-cooled IPM motor makes 250lbs•ft of torque, generates over 100hp, and employs a proprietary cooling system to allow a higher percentage of that peak power to be used over extended periods of time. This is particularly important because of the large gap between peak power figures and sustainable power figures in the electric motorcycle world, with the latter being the more important figure to quote.
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.
After teasing us time and time and time again, Yamaha Europe has taken the wraps off its 2010 Yamaha FZ8 (and it’s cousin the 2010 Yamaha Fazer8). As was expected, the FZ8 is a 779cc naked street bike that borrows its heritage from the FZ1, and replaces the FZ6 in the European line-up.
While the FZ8 looks well and good, Yamaha has proven that a copy of a copy never carries over well. The FZ8 motor is in essence a smaller bored FZ1 motor, which is itself a de-tuned R1 powerplant. As such the Yamaha FZ8 puts out a solid 104hp, which may disappoint many riders. Torque lovers rejoice though, the 2010 Yamaha FZ8 makes an impressive 62lbs•ft of wheel turning power from its 779cc’s.
Aprilia USA, the North American importer and distributor of Aprilia Motorcycles and scooters has sent out an update on the recall for the 2010 Aprilia RSV4‘s motor, saying that replacement motors from Italy have arrived, and that the company is ready to begin replacing affected machines. Aprilia USA expects the recall to take two to three weeks to replace every RSV4 motor sold in the USA, but it’s unclear how long it will take for the Noale brand to recover its lost footing with would-be Aprilia purchasers.
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.
There’s be some trouble brewing in the MotoGP/WSBK camp after news hit that MotoGP would be switching back to a 1000cc format by the 2012 season. In that story, several possibilities on how that format would work were put forth by various sides, one such proposal being the running of production based motors in MotoGP.
These motors, which would be based off those found on streetbikes, could be tuned to any degree, provided it met the criteria in the MotoGP rule book (1000cc & four-cylinders are the only regulations agreed upon currently). This news of course drew the ire of World Superbike promoter, Infront Motor Sports, in the form of Paolo Flammini, who believes that format would infringe on his license to exclusively run a production based race series.
Refusing at first to define what a production engine is, Dorna’s Carmelo Ezpeleta is now switching gears and saying the term “production engine” won’t even appear in the new MotoGP racing regulations.
One of the cooler things on display at EICMA this year was BMWs S1000RR engine cutaway. The cutaway showcases everything from airbox to exhaust, and if you look really closely you can spot the unicorns secret responsible for BMW’s 193 claimed crank horsepower.

The rumors appear to be true, and the BMW R series is getting an update to its motor for 2010. Maintaining its existing 1,170cc displacement, the most notable change to BMW’s flat boxer motor is a dual-overhead camshaft (DOHC) cylinder head setup, which was previously only seen on the HP2 Sport.
With the bore and stroke staying the same for 2010, the R lineup will continue to use the same 101 x 73mm cylinders, making a total of 1,170cc’s. The real changes and improvements come from the new cylinder head design. The DOHC design features two chain-driven camshafts, with each camshaft controlling both an intake and exhaust valve in the radial four-valve head.
When MotoGP switched from the 990cc displacement format to the 800cc formula, it was done so on the idea that it would make the premiere racing class safer for the riders. This proved to not be the case, as the 800cc bikes clearly carried more corner speed through turns, and were still able to approach 990cc top speeds on the straight-aways.
The result, a racing class that was more dangerous and more expensive for manufacturers.With this in mind, Dorna Boss, Carmeloa Ezpeleta, wants to return the series back its previous 990cc format, by as early as 2011.
The 2010 Honda VFR1200F is the most advanced motorcycle ever to come out of Honda’s factory, and is probably one of the most innovative motorcycles ever. A large portion of the technology that separates the VFR from the rest of the pack is the all new V4 power-plant that Honda engineers say is a trickle down product from their MotoGP racing efforts.
