I take that back,they were 40mm Keien flat slides that were for sale,I should see if he still has them. They were on a gsxr1100,a guy I know from the YMCA. He sold it to buy a new Rlast yr. But a set of Keien flatslides are up around a grand
! I ended up putting $500.in a back shock instead after already having a gsxr shock. I found that HP is great,but may not actully get me around the track any faster. (if I ever get back on the track,now shooting for 6/25) If I were running on the drag strip,the flatslides would be the ticket. But for my riding,its hard to justify spending the grand. Dan Lander
