Superlite 415 XD Series Chromoly Steel Front Sprockets – Yamaha R3


SKU: N/A Categories: ,


Superlite front sprockets are made from case hardened chromoly steel and machined to exact tolerances to outlast most sprockets on the market today.  The exclusive “XD” tooth profile offers a precise fitment over other brands.

This is a 415 series replacement front sprocket only and will only work with a 415 size chain.  See our other listings for the complete 415 chain kit.  This sprocket will not work with the OEM chain.  This high strength, lightweight sprocket weighs only 3.7 oz.

Changing from a 520 size chain and sprockets to a 415 chain and sprockets on the R3 makes a significant performance improvement.

I dyno tested this upgrade to prove the difference.  These 2 dyno runs are done back to back (about 20 minutes apart, as fast as I could pull the wheel and change the chain and sprockets) with the same bike, settings, dyno, tune, everything identical, and in the middle of the day after lots of other runs so the bike and dyno are hot.  These are each the best of 5 runs to be sure everything was even.  You can clearly see that the 415 kit improved peak power to the ground by .62 hp and torque by .29 ft lbs and improved performance across the entire power band.

Yamaha R3 415 kit vs 520 kit performance horsepower gain


This sprocket has a thin boss sticking out one side and a thicker boss sticking out of the other side.  This allows for a small adjustment in chain alignment if necessary.  Most of the time, the best alignment is achieved by installing the sprocket with the thicker boss sticking out away from the bike.
