1990 Beta ALP 240 Technical Analysis & Specification Breakdown

In factory specification, peak output is rated at 12 HP (8.8 kW) at 5,800 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 50.2 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
