2018 GAS GAS TXT GP 280 Technical Analysis & Specification Breakdown
Built around GAS GAS's trial motorcycle platform, the 2018 GAS GAS TXT GP 280 relies on a 272.2 cc (16.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 76.0 x 60.0 mm (3.0 x 2.4 inches).
On the scales, the TXT GP 280 measures 67 kg (148 lbs) dry. Rider ergonomics and chassis geometry center around a 650 mm (25.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry.
