jse Posted September 19, 2008 Report Share Posted September 19, 2008 Does any one know the diameter and the depth of the bore of the clutch slave cylinder on any modern bike? Not sure of the depth (the "effective stroke" would be a better gauge), but the GasGas "Edition" type model, say a 2001 TXT has a servo cylinder bore of 28.5mm+-, and the Pro model, 2002 on up, has a servo cylinder diameter of 14.34+-mm.

brian r Posted September 19, 2008 Author Report Share Posted September 19, 2008 Thanks Jon, Do the master cylinders have the same bore between models? I'm shocked at the difference in bores. Quote Link to comment Share on other sites More sharing options...
jse Posted September 20, 2008 Report Share Posted September 20, 2008 Thanks Jon,Do the master cylinders have the same bore between models? I'm shocked at the difference in bores. It is interesting that, with minor exception, the standard bore for the GasGas clutch master cylinders is 9.5mm for both the Edition and Pro models. They are, of course, quite different clutches, which may explain the difference in bore sizes as the Pro looks like it requires a longer effective stroke due to the servo cylinder acting on the clutch fingers, that in turn act on the pressure plate. The Edition servo cylinder, in effect, acts directly on the pressure plate.. I would imagine that you'll find the 9.5mm M/C bore fairly common for a lot of the bikes.

copemech Posted September 22, 2008 Report Share Posted September 22, 2008 Brian is obvoiusly up to something wierd here! Probably something similar to a Scorpa clutch, to adapt to a Honda! Quote Link to comment Share on other sites More sharing options...
