Fully assembled 80CC 2-stroke engine. Single-piece balanced crank, stroke 40mm. During the running-in phase, the speed should not exceed 20km/h, and the engine should not bear excessive load. Otherwise, it will cause the engine to overheat, seize the cylinder and accelerate the wear of parts.
This product would be ideal for individuals looking to upgrade or modify single-cylinder 26-28" bikes by providing a powerful 1.65HP 2-stroke engine.
