IAME S125 Engine

The newly engineered IAME S125, single-cylinder, 125cc two-stroke, water-cooled engine is designed specifically for Karting.

The project is conceived to combine the ease of use of electric started engines with the philosophy and technical solutions shared with high-end racing engines.

The performance level meets nowadays Drivers requirements and the power curve is designed to provide strength yet from the lower revs.

All such is achieved with finest engineering and without the need of an exhaust valve, to preserve ease of use and low maintenance.
