Drawing on the proven design of the Minarelli platform, the IM70 reimagines this classic engine architecture with upgraded materials and engineering to push the limits of 2-stroke power.
The iron cylinder delivers unmatched strength and high-temp resistance, while the stuffed crankcase and CNC billet intake system create near case-reed-like performance without the complexity.
