415 Chain and Sprocket Kits for Race Use – Yamaha R3

This is for closed course race use only.  We do not recommend using 415 chain and sprockets for street use.  It is critical to monitor chain tension and chain and sprocket condition when using a 415 chain and sprockets.  We highly recommend using a rivet link with your 415 chain, and replacing the chain at least every 800 miles.

This kit will reduce the rotating mass of your drive assembly by over 2.5 lbs.  This large reduction in weight and friction translates to .6 extra HP being transferred to the ground instead of being lost to friction.  You also will notice faster acceleration and better handling by reducing the gyroscopic effect of the rotating mass.
