***The Yamaha R3 typically requires a 142 or 144 link 415 chain! This EK 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.
OZ Racing, BST, and most Marchesini aftermarket wheels use a different bolt pattern from OEM for rear sprockets. 5 bolts, 10.5mm diameter, on a 100mm bolt circle with 76mm center hub diameter. Use these sprockets instead.
*(Marchesini wheels for Yamaha R3 use OEM sprockets)
*These sprockets are special order only, no returns.
***Be skeptical of less expensive ceramic bearings! True ceramic ball bearings are expensive to manufacture. Inexpensive ceramic bearings often contain hybrid ceramic coated steel balls, which do not offer the extreme long life or weight savings of 100% ceramic balls.
