BCR offers bolt-on polished aluminum gas tank and seat combo for Honda CBs, Yamaha XS, Hinckley Triumph Bonnevilles and Harley Davidson Sportsters. We could make a tank and seat that are completely original, but if you want a tank and seat made back in the old days like Manx style or Matchless look, just email us and we'll see what we could do. Depending on what bike you have, we could make the tank and seat bolt-on parts. Just like all BCR parts, the tank and seat are made in-house from scratch. Any specs you want on the tank and seat, we could make the necessary adjustments in-house. The tank and seat are made from 2mm aluminum flat sheet. The gas tank comes with aluminum gas cap, and the necessary bolt-on mounting brackets. The seat comes with bolt-on upholstered seat pad and mounting brackets. The seat could be ordered with or without tail light. Please email us for estimated time of construction. If interested, please feel free to send us an email inquiry.
