428 Rear Sprockets
You won't find this technology anywhere else because we are the first people to bring this to the UK straight from our MOTO 2 experience.
Our 428 chain & sprocket kits are designed to work on Supersport, Superstock or Stock 675/600 race bikes. With only 10% less tensile strength than a 520 chain you can reduce the weight of your 520 race kit by 30% without compromising either the reliability or longevity of your chain or sprocket set and the benefits don't stop there.
With more teeth on a smaller diameter sprocket, you can now do much finer gearing adjustments simply and quickly. You will also notice that using these sprockets reduces the effect on your wheel base when you change gearing. We will guarantee you this is one of the best accessories you can buy!
