Yes Oberon one gives you a lighter clutch as the unit has a bigger piston. Mine has 40mm piston the one Art is trying has 38mm. On track at the weekend so can give it a good workout to make sure the clutch isnt dragging. If it does they will use the 38 piston but at the moment seems fine! Stock is 16nm to pull the lever, was 13 with the 40mm unit.
Had a test blast on my Blade today to Newlands corner then boxhill to test the TSR Race clutch slave . Its very easy to pull in the clutch lever an a much smoother feel .
