Technical Overview
1981 Triumph T140 ES Bonneville Royal Limited Edition Technical Analysis & Specification Breakdown
At the heart of the 1981 Triumph T140 ES Bonneville Royal Limited Edition classic motorcycle, Triumph pairs a 750 cc (45.8 cu in) air-cooled twin, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 76.0 x 82.0 mm (3.0 x 3.2 inches) with a 7.9:1 compression ratio.
On the scales, the T140 ES Bonneville Royal Limited Edition measures 199.6 kg (440 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 787 mm (31 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,422 mm (56 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 5.22 L/100 km provides an estimated theoretical range of roughly 345 km (214 miles) between fill-ups, while factory top speed is listed at 180 km/h (112 mph).
