I have a Maxton Race shock from a 1098 . It comes with a 500b/87.5NMmm spring ( this equates to ~90KG or -29 in Ohlins speak!) It has a few cosmetic marks from where it rubbed on the subframe but otherwise in VGC and 100% functional and amazing bit of kit £495 I also have a much heavier spring 11.0 (for use with a track link or 100KG+kit rider) in black for an extra £30 PM me if you want more info
