In the opening round of the World Superbike championship at Phillip Island, the factory Aprilia squad introduced a new specification engine. The new RSV4 race enigne features gear driven cams instead of chain driven cams, which are on the homologated road bike.

Aprilia claim that the rules allow them to make the change to gear driven cams and that they also gained approval from the FIM (the sport’s governing body) to introduce the new technology. Gear driven cams are generally unused on road bikes due to their high cost but are regularly seen in the world of MotoGP – not WSB.

At Phillip Island rival manufacturers met to discuss Aprilia’s use of the gear driven cams and then stated their argument to Aprilia boss Gigi Dall’agna.

BUT the whole point of the homologated bike rules are that it MUST be available for the general public to purchase from dealers and the Gear driven cams are not so its cheating, the points should be removed from the Team and the bikes banned from racing till the chain cams refitted or gear driven cams are available for sale.

All they need to do is make the geared cams an optional accessory for the homologated bikes.  But of course I think the Factory bikes should have a bit more HP than what they do. :P

That is just plain petty... It is not as if they are using special manufactured Cranskshafts or one of connecting rods/ and special purpose built pistons. Lighten up Ducati,Yamaha and all the rest of those poor us "we must win always manufactuers"
