Sirio .21 RVS clutch system

Following the successful launch of the .12 RVS clutch back in August, Lavorazioni Meccaniche S.r.l – Star Motor Engineering have now produced a new .21 RVS clutch system. The new clutch system uses the same new design and way of working as the previously released version, with the weights and shoe working in a completely different way to increase performance and acceleration of the engine. The power clutch kit has a lightweight flywheel with a new ‘flat design’ and the Italian company has also worked to balance it to get the most performance from the engine. All parts such as the spring catch, flywheel nut and spring nut are made from premium Swiss 7075 T6 aluminium for maximum lightness, while the new clutch disk is hardened for durability. Expect the new clutch system to be released in late December.
