Malossi, whose expertise in balancing a vast experience with the latest technology, embraced this new challenge: to bring to the racetrack a fuel injected two stroke engine.
With the new INJECTION TECH range of products a new chapter is written, an answer, the racing world was anticipating, to satisfy the growing number of Malossi Trophy Races for 70cc scooters.
TECHNICAL FEATURES cylinder kits
CAST IRON CYLINDER - Technology
