Late 60's Triumph Bonnie Gas Tank
Ready for shipping the third week of August, 2008!
Order yours now, quantities are limited!

Part number 83-1798 raw steel fuel tank is as supplied on the late 1960s Bonnies, but will fit all unit construction pre1971 Triumph 650 models. The Taiwan manufacturers are using thicker gauge steel than original for strength and to meet DOT regulations for fuel tanks. These tanks are a virtually exact replica for the impossible to find tank that is missing from so many bikes. These will take the standard badges, tank beading, kneegrips, fuel taps and caps, all stocked by BCS and available through any BCS dealer, or the badge holes can be filled in and painted over or decals can be fitted. If you are restoring or are building a bobber don't miss out! Order today.
