Technical Overview
2020 Yamaha 135 LC Super Sport Technical Analysis & Specification Breakdown
Built around Yamaha's scooter motorcycle platform, the 2020 Yamaha 135 LC Super Sport features a 134 cc (8.2 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12 HP (8.7 kW) at 8,500 rpm while maximum torque reaches 11.8 Nm (8.7 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 89.6 HP per liter and a 3,000 rpm working window between peak torque (5,500 rpm) and peak power (8,500 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 135 LC Super Sport measures 105 kg (231 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (8.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,240 mm (48.8 in) wheelbase engineered for quick, flickable steering geometry. The 4-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
