Engine Displacement: 294.72 cc
The Jawa 42 is powered by a 294.72 cc, single-cylinder, liquid-cooled engine. It features a high-compression setup with a bore of 76 mm and a stroke of 65 mm. This "short-stroke" nature allows the bike to rev higher and more freely than its long-stroke British-style rivals.
Max Power: 27.32 PS
Generating a peak power of 27.32 PS, the Jawa 42 leads its class in power-to-weight ratio. The power delivery is linear, making it exceptionally capable for both quick city overtakes and sustained highway speeds.
Max Torque: 26.84 Nm
The engine produces a maximum torque of 26.84 Nm at 5800 RPM. This mid-range punch is a result of the J-Panther engine's internal refinements, providing immediate throttle response.
No. of Cylinders: 1
The motorcycle uses a single-cylinder configuration. To manage the inherent vibrations of a high-revving single, Jawa has integrated a counter-balancer shaft that keeps the ride smooth up to the redline.
Valve Train: DOHC
A standout feature in this segment is the Double Overhead Camshaft (DOHC) with a 4-valve head. This allows for better high-end breathing and more precise valve timing compared to traditional SOHC engines.
Fuel System: FI (Fuel Injection)
The electronic Fuel Injection system ensures optimum air-fuel mixture across varying altitudes in Nepal—from the plains of Terai to the hills of Kathmandu—improving cold-start reliability and efficiency.
Top Speed: 130 kmph
The Jawa 42 can comfortably reach a top speed of 130 kmph. Its 6th gear acts as a tall overdrive, allowing the engine to sit at lower RPMs during high-speed cruising.
Mileage: 33 kmpl
The real-world mileage of the Jawa 42 is approximately 33 kmpl. While high-performance riding can drop this, careful throttle management on highways can push it toward 35 kmpl.
