From stock we can supply a large range of chain and sprocket kits. At MR Motorcycles you can purchase individual front and rear sprockets with a different chain length 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 have on offer a range of coloured EK chain and to compliment these chains we supply a large selection of JT sprockets. Replacing the rear sprocket don’t forget to check the sprocket drive rubbers / bushes and bearing.
