Performance and balance from the O.S. Engine OS-1A301

The O.S. Engine OS-1A301 is crafted for hobbyists who want a refined, race-capable engine for both cars and buggies. Its design focuses on predictable responses and ease of tuning on the track.

Carburetor refinements for steady fuel delivery

The updated carburetor on the OS-1A301 improves fuel metering and efficiency, helping drivers maintain consistent run lengths of about ten minutes per tank under typical conditions, which is great for longer heats.

Lowered centre of gravity from the compact head

The unit's low-profile cooling head reduces the vehicle center of gravity by 17 mm, improving turn-in and mid-corner stability while still offering adequate cooling during extended runs.

Well balanced power and RPM flexibility

Featuring 3.46cc displacement and a 16.40mm bore and stroke, the OS-1A301 reaches a peak of 2.61HP at 34,000rpm with a practical band from 4,000 to 42,000rpm. Weighing 347g with the T2090SC muffler, it keeps weight where you want it for handling.
