@oldslowsledder, similar results today. It's the 897 Ramps in the Mach Clutch, designed for the Launch Control. Switched back and forth with the XRS 900 Turbo R. It has the 880 Ramps, as well as the rest of the 900 Turbo R's...Something to get used too. The engagement definitely is noticeably harder then the 880 ramps. I am head over heals with these 2 sleds. Looking forward to picking up @Mrs Turbo Doo 900 Turbo R Enduro..
