    916 or VFR 400 wheel, 900ss shock?

    Has anyone tried fitting either a Ducati 916 or VFR 400 rear wheel to a Hawk?

    Both of these use a centre nut as opposed to the VFR750's 4 stud, so would seem like an easier swap, although I don't know much about either.

    Also thinking of a Ducati 900ss rear shock, as the ss has no linkage might not neet to change the spring. Seems to be slightly longer but am more concerned about the rigidly fixed resevoir clearing the Hawk frame. Has anyone else tried this swap?

    Finally, saw this pic and thought that it looked like a good idea. Instead of moving the whole footrest, this guy has left the top mounting bolt in place and rotated around that, so giving some backward and upward movement. Would still need some sort of bracket for the lower mounting bolt, but probably less work and more of a stock look.

    As to the pegs, I haven't ran that kinda setup, but Two Brothers Racing used to sell a kit that did just that. It was a triangular 3 bolt rearset adapter. I tried to buy a pair last year, but they were no longer being made.

      Well you mentioned the VFR750 wheel so here is one that was prepared earlier


      If you go this route you can fit a 170 tyre, but not if you choose the VFR400

          Thanks for the info guys. Really useful. Like the look of the first Ducati wheel pic best, but guess then I should fit a front end that matches.

          Only just got the bike, so repairs to do first then on to the project this winter.

              Hey Dirk, do you know where the tail section on the blue hawk came from?

                  I have a 900ss I will take a look and see if that shock would fit.

                    900ss shock

                    make sure spring and dampining rate are at least close to a hawk shock

                      could a VFR shock be used? The lower mount should be same due to the swing arm bing the same cast part.

                        I do not think that the VFR shock would work. The single-sided swingarm from the 1990-1997 VFR750 & the 1998-2007 VFR800 is not the same as the one used on the Hawk.

                        The VFR swingarm has a hole up front, and the VFR shock passes through the hole & mounts via a rising-rate linkage.

                          Doesn't look like the 900ss shock will work.
