Yamaha TT350 Motorcycle - Dual-Sport (1986-1987)

The Yamaha TT350, produced for the 1986 and 1987 model years, was a lightweight, four-stroke off-road motorcycle designed to bridge the gap between smaller trial bikes and larger enduro models. Known for its reliable performance, it appealed to both recreational and experienced riders. It was powered by an air-cooled, single-cylinder, 349cc (or 346cc) DOHC engine, delivering 32 horsepower at 7,000 rpm and 33 Nm of torque at the same RPM. This engine was a modified version of the XT350's powerplant, featuring enlarged intake ports, new valves, more aggressive camshaft profiles, and re-tuned carburetors with Yamaha's Dual Intake System (YDIS). The electronic ignition was recalibrated, and the six-speed transmission received beefed-up gear sets and new ratios for off-road use. During its brief production run from 1986 to 1987, the Yamaha TT350 was offered as a single model without distinct trim levels. There were no significant mid-cycle generation or engine changes reported between the 1986 and 1987 models; specifications and features remained consistent. FAQ:
