NX4 Honda RS125 Moto Bum kit cylinders NOS BUM 03

NX4 Honda RS125 Moto Bum kit cylinders NOS, BUM 03. We believe this is a new cylinder, some of the ports look to have been finished by hand. Motobum sold their cylinders without nicosil, leaving this to the customer to arrange - so please note, you'll need to get the det ring and nicosil completed before use.

We can arrange this in the UK, but the finish takes some time, around 3 weeks for nicosil. If you need the deto ring fitting, this takes longer, as there are less companies that offer this service.
