Clutch Adjustment Aprilia MX125

[WheelieKid]

My Aprilia MX125 has a clutch problem, the lever is floppy and doesn't engage the clutch when pulled in. It has been adjusted all the way on the handlebar, however when I tried to adjust it in the case, the bolt wouldn't turn.

Any help is greatly appreciated.

Without seeing a photo of the case end adjustment of the cable, it’s difficult to say.

Often there are 2 nuts which determine how far the cable is from the lower arm. One is a locknut or fits into a flat point on the adjuster, so you loose the nut at the other end of the adjuster to free it to adjust the position if the nuts on the threaded spline.

You might need to take off one of the side covers but with that sort of bike it should be easy enough to disconnect and remove the clutch cable. I'd check it's not damaged or kinked. If in any doubt, get a new clutch cable as that's a cheap and easy to swap component. You might get lucky an drop an "aha!" moment when you try and take it off

After that take a look at the clutch itself. Have you got anything fancy on there like a Rekluse or is it stock?

Can you upload a photo of the bottom end of the cable?

If the clutch isn’t disengaging properly the gears probably wouldn’t select. Have you sorted the clutch fully?

If you've adjusted all the slack out of the cable but the clutch still won't disengage to allow a gear to be selected, then if you have adjusted it the correct way, and not played around remounting the arm at the lower end, then without seeing the photo's of the adjusters at each end, it's a guessing game.

It sounds like your adjustment is wrong. When the plates wear or the cable stretches, you're adjusting the cable to be longer, so more thread should be showing at the top adjuster, so more towards the middle of the cable and more should be showing towards the middle of the cable at the lower end.

Photo's would help.

If this is a genuine club with hydraulic ramps etc, there must be someone there who knows what they're doing and can give it a quick one over surely?

Hi,
Apologies if this has already been said or I've not read this properly but doesn't your bike have a rotax 122 engine, same as the rs?
If so then clutch adjustment is also done at the engine end.
Remove plastic cover & use the "special tool" supplied by aprilia to loosen adjuster.
It's actually just a cheap alloy box spanner & can be substituted for a 1/4" socket (10 or 12mm irrc), & mole grips.
It all becomes obvious when you.pop off the plastic cover

cheers,
GAZ
