Forgot I had this too My 749r I just sold had an STM 48t slipper You need a special stm tool to take it in and out This is it £50 plus postage (cost £160 I think)
Don't worry, the STM tool is made for holding the STM pressure plate only - it won't work with other clutches and I highly doubt your Oberon one is for STM clutches.
I have both mate. And the Oberon does both the 12 and 48T clutches but as you say, only around the basket.
But didn't STM / EVR make a fancy holder for the basket? The one I have looks to be for the pressure plate jobby on the newer type slipper plates
Cheers mate. Thanks for the photos. That is similar to the one I have at work. Cheers, Ian Sent from my iPhone using Tapatalk
