899 To Slipper Or Not To Slipper

Yes fast road miles. Why wouldn't you have a slipper, it's one of the best mods you can make imo.

 

I have a Sigma, but there's probably no difference between the two. The slipper was standard in the little KTM

 

Get a slipper. Track essential

 

Don’t forget EVR. Andy

 

I had a sigma slipper in my gsxr if not used within 2 weeks it would jam up and you'd have to get the bike hot and try and unstick the plates, the archie bike has a stm slipper and never had a problem with it.
