Motorcycle Cylinder Barrel Repairs and Re-Bores

We offer a few services depending on what type of barrel you have:

Steel Liners and Re-bores

it may just need re-boring for the next oversize piston. This can be done easily and we can supply a range of pistons and gasket sets usually from stock including Mitaka, Wossner and Wiseco. We can also fit a new steel liner to your original cylinder if yours is damaged or beyond re-boring. Fitting a steel liner can also be done as a cheaper alternative to re-plating a Nikasil cylinder.
