Originally conceived for the 1963 model year, by west coast distributor Bill Johnson of Johnson Motors, the TT was a high performance, factory race bike, stripped down and performance tuned to fill the niche markets of off-road racing.  In 1967, at the end of its limited production run, only 900 TT Specials were built. 

Beginning with and improving upon their street legal Bonneville, the Triumph factory racer came with bigger carbs, higher compression pistons, hotter camshafts and a high output ignition system, to produce 54hp at 6,500 rpm. Closer ratio gears were installed in the four-speed gearbox, chain drive sprocket ratios were altered, and larger diameter exhaust pipes were tucked under the frame, without mufflers. Aluminum, or more durable stainless-steel fenders replaced the street items. Lights, fork lock and speedometer were deleted and only a tachometer was fitted. The forks received special springs and internal valving. These stripped-down bikes weighed 350 pounds, some 30 pounds lighter than the stock configuration.

To further differentiate the TT from the street models, the Bonneville-derived 2 ½ gallon fuel tanks came with special paint schemes. For 1967 the colors were aubergine over either gold or white, pin-striped in gold by hand.

This motorcycle was meticulously restored in 2006 and 2007. The goal was to retain all the original parts with their original-style finishes. Every nut and bolt and other parts cad plated were newly cad plated. The tank was painted with acrylic lacquer mixed to the factory paint codes and the gold stripe is hand laid. 

For durability, the frame and the fender braces were powder coated gloss black. All other parts were painted with acrylic enamel as original. Any unpolished aluminum castings were left unpolished. All chrome parts were re-plated. The handlebar grips are correct, and the seat cover is a NOS original.

The engine was completely rebuilt with NOS parts, re-bushed and re-sealed, with new .040 over pistons for the original 11:1cr. The transmission was inspected and in like-new condition, but it was re-bushed and re-sealed anyway. The ignition is all NOS Lucas. Wheels are original factory Dunlops that have been re-chromed and laced with stainless steel unpolished spokes. The front and rear tires are original Dunlop K70s with the script ‘Made in Great Britain.’ The bike comes with a VMCC Extract from Works Record confirming originality.

Cosmetically, the bike presents beautifully in concours condition. The only detraction is the aubergine paint has faded to more of a burgundy color and there is a ding in it (photographed) – an easy fix and I would be happy to take care of it upon a confirmed deal.

Fresh from a full re-commissioning and service, the bike starts very easily in 1-2 kicks and has an extremely taut feel to the engine. Power is fantastic and plentiful, brakes work as they should and the suspension feels freshly restored. I suspect the bike was used very little since restoration. Shame. It’s a blast to ride and loud!

This motorcycle is offered on Bill of Sale, but we can obtain a clean, clear California title on behalf of the buyer.
