Anyone know what the new gear reduction ratio is on the Apex for the clutch/crankshaft gear reduction?
I heard that it was changed from the RX-1, but havn't been able to find it.

37 gear on the pto shaft, 30 gear on the crank for a 19% reduction where as the RX-1 was a 37 gear on the pto shaft and a 31 gear on the crank for a 17% reduction.
