I have a Sigma slipper clutch for 899 for sale. Supplied to Sam Middlemass in the trioptions direct from Neil Spalding at Sigma with his "Anti wear" modification. (Note Copper rivets around circumference of back plate) 100% carried out by Spalders for Sam. I believe it to have very low use as its in excellent condition in original packaging. I never got round to fitting and has been sat in my garage since. £350 delivered, final bump before it goes on eBay. Must be the cheapest 899 slipper to ever have been up for sale. Some one must be building a 899 track bike.
