TT 600 R

1999 Yamaha TT 600 R Technical Analysis & Specification Breakdown

Built around Yamaha's enduro - offroad motorcycle platform, the 1999 Yamaha TT 600 R relies on a 595 cc (36.3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 43 HP (31.4 kW) at 6,500 rpm while maximum torque reaches 50 Nm (36.9 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 72.3 HP per liter and a 1,500 rpm working window between peak torque (5,000 rpm) and peak power (6,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the TT 600 R measures 154 kg (340 lbs) wet (curb), translating to a power-to-weight ratio of 0.28 HP/kg (3.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 945 mm (37.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 10-liter (2.6 US gal) fuel tank paired with a rated consumption of 5.9 L/100 km provides an estimated theoretical range of roughly 169 km (105 miles) between fill-ups, while factory top speed is listed at 150 km/h (93 mph).
