Couch is still waiting on me to send my 800ss racebike rearsets...but I've been tardy due to some personal problems occupying my attention of late. This weekend Tony! Honest!
Ducati Performance one for 916/996 family fit - if you use the top and bottom mounting holes - but they give quite a high foot position. i raced with these but reverted to standard pegs towards the end of this season.
I also have a set of Fast by Ferachi rearsets specifically for the 620SS - these give a slightly higher foot position than standard. However one of the knurled foot pegs is missing (busted in a get-off last year).
Otherwise I found rearsets for the injected SS family to be a bit thin on the ground!
