2017 Tomos Racing TT Technical Analysis & Specification Breakdown

Built around Tomos's naked motorcycle platform, the 2017 Tomos Racing TT utilizes a 49 cc (3 cu in) air-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 38.0 x 43.0 mm (1.5 x 1.7 inches) with a 10.0:1 compression ratio.

On the scales, the Racing TT measures 65 kg (143 lbs) dry. Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,160 mm (45.7 in) wheelbase engineered for quick, flickable steering geometry. The 3.5-liter (0.9 US gal) fuel tank paired with a rated consumption of 1.8 L/100 km provides an estimated theoretical range of roughly 194 km (121 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).
