Questions riders ask

520 on every full size bike, 428 on the 85s and big wheel minis, 420 on the 65s and small minis. The stamping on your current chain side plate says which.

Standard for motocross, where weight and drag matter and the chain is replaced often. O ring or X ring for enduro and trail, where it lasts three times longer.

Members pay the member price shown on every product, which is under RRP across the RK range, and get free standard shipping on orders over $10. Membership is $5 for the first month.
