More power and carbon swingarm for Yamaha at MotoGP Misano

Yamaha’s Valentino Rossi and Maverick Vinales will benefit from a couple of extra horsepower and better tyre life courtesy of a new carbon swingarm at Misano’s MotoGP round, team boss Maio Meregalli has revealed.

The team tested a new, double-exit exhaust at the track recently and Meregalli said it had released some more hosses from the inline-four engine.

“We tested the new exhaust system, which makes the power delivery much more linear,” said Meregalli.

“This applies to the entire power curve - from the first moment on the throttle up to 100 per cent. We have a few more horsepower, that will never hurt.”

Grip on used tyres has been a constant issue for both riders and Meregalli says the new swinger will also see improvements.

The carbon swingarm was also approved, providing more stability and traction - not necessarily in a slanted position, but as soon as the bike is up.

“We expect this new component to put less strain on the tires, even though we did not do a real race simulation because we only had a little time left.

“The new swingarm is also lighter than the one in aluminum - and saving weight is always good. We also tried a cover on the rims to improve the drag coefficient. The drivers liked all these things and the improvements will be available from Misano.”
