At the heart of the 1991 Yamaha TT 350 enduro - offroad motorcycle, Yamaha utilizes a 346 cc (21.1 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 33 HP (24.1 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 95.4 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the TT 350 measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.25 HP/kg (3.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control.
