A fresh set of sprockets and a new chain makes your bike ride smoothly again. Are yours worn out or do you have a big ride coming up? I can fit a new set for you for $50.00 plus the cost of the products. The current price (02/2024) for the set shown in the pic is $221.00 and are suitable for a DRZ400 e using the very popular 15/44 sprocket combo. Please note - As with the above combo, occasionally a different case saver is required to take a larger front sprocket than standard size. Flick me a message if you would like to discuss. You can also do this item as a workshop if you like. You swing the spanners and I provide the instruction.
