2021 Jawa 350 OHC Technical Analysis & Specification Breakdown
Positioned in Jawa's custom - cruiser motorcycle lineup, the 2021 Jawa 350 OHC utilizes a 350 cc (21.4 cu in) air-cooled twin, four-stroke layout. In factory specification, peak output is rated at 27.4 HP (20 kW) at 6,500 rpm while maximum torque reaches 30.6 Nm (22.6 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 4-speed gearbox. With a specific output of 78.3 HP per liter and a 1,500 rpm working window between peak torque (5,000 rpm) and peak power (6,500 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 350 OHC measures 160 kg (353 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (5.84 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
