Engine and Transmission of Jawa 350 in Nepal

Engine Displacement: 334 cc

The "Alpha2" engine is a liquid-cooled, DOHC unit shared with the Perak but detuned for a flatter torque curve. This version prioritizes low-end tractability over high-RPM peak power, specifically to compete with traditional long-stroke "thumpers."

Max Power: 22.57 PS

Peak power arrives at 7,000 RPM. While lower than the previous 293cc engine, this tuning reduces engine stress and heat, providing a more relaxed character for long-distance touring in varying altitudes.

Max Torque: 28.1 Nm

Torque peaks at 5,000 RPM, offering a "meaty" mid-range. This allows the bike to hold higher gears at lower speeds, a significant advantage for navigating the steep inclines of the Kathmandu valley and beyond.

No. of Cylinders: 1

A single-cylinder layout keeps the chassis slim. It utilizes a balancing shaft to mitigate the vibrations typically associated with large-displacement singles, ensuring smoother handlebar and footpeg feel.

Valve Train: DOHC

Double Over Head Camshafts with 4 valves allow for precise timing and better volumetric efficiency compared to SOHC rivals, maintaining performance even as air thins at higher elevations.

Fuel System: FI (Fuel Injection)

Closed-loop Electronic Fuel Injection ensures optimal air-fuel ratios. This system is critical for maintaining fuel efficiency and meeting BS6 Phase 2 / Euro 5 emission standards.

Top Speed: 125 km/h

Electronically limited/drag-limited to roughly 125 km/h. The 6-speed gearbox allows for a stress-free "cruising speed" of 90–100 km/h without excessive engine buzz.

Mileage: 30 kmpl

Real-world combined mileage is approximately 30 kmpl. The liquid cooling system plays a vital role here by preventing thermal efficiency loss during heavy city traffic.
