1970 Jawa 350 Californian Technical Analysis & Specification Breakdown

Positioned in Jawa's classic motorcycle lineup, the 1970 Jawa 350 Californian relies on a 343 cc (20.9 cu in) air-cooled twin, two-stroke powerplant. In factory specification, peak output is rated at 18 HP (13.1 kW) at 5,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 52.5 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
