Positioned in Paton's sport motorcycle lineup, the 2020 Paton S1-R Lightweight Race Edition pairs a 649 cc (39.6 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 83.0 x 60.0 mm (3.3 x 2.4 inches) with a 10.8:1 compression ratio.
Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,390 mm (54.7 in) wheelbase engineered for quick, flickable steering geometry. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
