From stock we can supply a large range of chain and sprocket kits. At MR Motorcycles you can purchase individual front and rear sprockets so that you can alter the gearing to suit your personal style of riding. The chains we supply and recommend are EK and DID. We have all sizes from 415-630 from a std chain to the extreme upgrade. We can offer a range of coloured EK chain. The sprockets we supply are JT sprockets. Replacing the rear sprocket don’t forget to check the sprocket drive rubbers / bushes and bearing.
