DID 415 ERZ 415 Gold Drive Racing Chain (120 Links) (with Clip Style Link)

From: $89.95

***The Yamaha R3 typically requires a 142 or 144 link 415 chain!  This 120 link chain is not long enough and 2 chains must be pieced together to get the correct length for the Yamaha R3.

*Note, you will need (2) master links to piece 2 chains together, so make sure you have enough master links.  IE. If you purchase (5) 120 link chains, you will need 3 additional master links to assemble (4) 144 link chains.

When using an 18t front sprocket, use the following as a guide for chain length:

54t – 142 links

55t – 142 or 144 links

56t – 142 links

57t – 144 links

58t – 144 links

59t – 144 links

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

I specifically 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 power to the ground by .62 hp and torque by .29 ft lbs and improved performance across the entire power band.
