The evolution of the Yamaha YFZ-R continues Yamaha's winning tradition of a competent chassis coupled with a powerful and reliable engine. Now with electronic fuel injection, this racer starts and idles like a docile street machine. We have also continued our evolution of go-fast parts for this popular quad. We have an all-new exhaust that makes more power than our pipe for the previous model. We also offer a full array of custom pistons, cams, porting packages, free air kits, and pre-programmed Power Commanders. Check out the dyno chart for the exhaust power gains.
