TY80 Tank & Seat Unit

Tank/Seat Unit

High quality white fibreglass seat & tank unit. Update your TY80 with the new seat & tank unit! The unit offers a big savings in weight; it is also narrower & lower than stock. Includes tank, seat, decals and petcock assembly. Uses stock gas cap, or we can provide a new one!

We highly recommend you coat your new tank with our tank sealant. This protects the tank from the additives in the US fuel supply, which do not necessarily like fiberglass. We can provide the sealant for a DIY experience or we can coat it for you.
Sealant only   $64.95
Sealant & labor  $100.00
