So I got to thinking about why I used an Apex motor in my race car and one of the main reasons is because it has a gear reduction. So even though the engine is revving 11,000+ rpms I think my final output rpm is only about 8,700. Drivelines usually don't like spinning past 9,000 rpms and I was curious how brutal the YXZ engine is going to be on the driveline if it doesn't have a gear reduction before the output shaft.
No, the 3 cylinder does not have a gear reduction in the engine like the Apex 4 cylinder. The triple spins at more belt friendly RPMs than the 4 cylinder, so it doesn't need it for the sleds. There is a gear reduction in the transmission before the clutch.
