Technical Rotax Clutch drum

[Sam Jilbert]

Hi there,
Just bought a new clutch drum assy for my rotax 125 and noticed it is different to the old part. The new one is 1-2mm shallower and has a rib around the outside. Is one the so called ‘old style’, and if so are the clutch drums interchangeable??

Most places I find the 'new style' clutch drum for sale, state that it's compatible with Evo or Pre Evo. So you should be good! How does it fit on the I assume, 'old style' clutch shoes?

The ribbed part is to stop the drum cracking apparently, new design.

@LMR might be able to advise?
