R&D new Monster charger wheel This is the new R&Ds Monster Compressor Wheel kit for the new Yamaha FZR engine. It promises to deliver horsepower you can feel providing instant throttle response, improved mid range acceleration and increased top speed performance. The stock Yamaha Supercharger is equipped with a 5 blade design wheel. R&D had designed a 9 blade one in the past while Riva had produced a 7 blade impeller for the same Supercharger. Recently R&D produced the pictured 11 blade wheel that Bill Chapin showed us in Havasu during the first testing we carried out together for the new FZR. The new wheel will be available soon along with some other tricky parts for the new Yamaha.
