Overview As the industry's first single seat youth model, the ACE® 150 EFI is designed to give kids ten years and older the joy of driving with adult supervision while providing safety features parents will love. Power The 149cc EFI engine delivers a fun ride, consistent starting, improved idle quality, and a crisp linear throttle response. ACE 150 comes standard with electric start and automotive style controls, making it easy for young drivers to hit the trail. Suspension Bumps in the yard and on the trail are soaked up by 5" of suspension travel up front and 6" of travel in the back. Plus a full 9" of ground clearance gives the ACE 150, and your young driver, the ability to navigate off-road obstacles.
