    F3 rear shock bolts up on the Hawk???

    So this guy on ebay says that the stock hawk shock bolts right up to the F2 and F3... so that also means then that the F3 and F2 shocks bolt right up to the Hawk! Right??? All the articles I have read say that there really is no stock shock that is a straight bolt on w/o modifications (i.e. 900rr shock)... anyone care to confirm?
    If the F3 shock bolts up, that would be great as that is adjustable and super cheap on ebay....

    in my mind the big Q would be does the F2/F3 have a direct bolt or linkage-type setup for the rear shock.

    if linkage the shock's spring, dampening and compression rates will be completely wrong for a hawk.

      your right about the linkage....at least for the F3, it has linkage

        The Hawk is one of the few Honda bikes with a mono shock with no linkage. The CBR600 family of bikes all have linkage design rear suspensions.

        The Hawk shock might bolt up to a CBR600 with no problems but as stated above "dampening and compression rates will be completely wrong".

        So just becasue it fits does not mean that it will also work.

        If you install a CBR600F2/F3 shock in a Hawk and you sit on the seat the back end of the Hawk might compress enough to hit the tire.

        Now come the big issue with the CBR900 rear shock in that it can be made to fit the Hawk by changing the spring and making some adapters and maybe a little grinding but unless you end up opening up the CBR900 rear shock and revalving it and putting in the correct weight oil all that you have done to your Hawk is installed a shock that looks cool since it has adjustment.

        Changing shocks out includes:
        1> proper fit in the frame and swingarm
        2> proper length of the shock to give the correct ride heigth
        3> Proper spring rate so that the bike will function as designed
        4> correct stroke to work with suspension design
        5> correct valving to work with all of the above

            haha... don't tempt me. I think I will get in big trouble if I do though, because I won't be able to buy Christmas presents then
            That was great info guys about the linkage. I never knew that... chalk one up for the board and info for others!
            So I'm guessing the 900RR doesn't have a linkage then??? Since a lot of people make that mod.

              The CBR900 has linkage!
              People have been using it becasue it is easy to fit to the Hawk with some simple machine work and a spacer or two but as I stated above just becasue it fits does not mean that it works properly. Yes, it might feel better to start and it lifts the rear of the bike which tend to look good but it is not valved properly for the Hawk.

              It tends to feel better becaue after installing it the bike handles differntly due to the increase in the rear ride height the bike tends to turns in quicker which makes the rider think the bike is handling better.

              I feel due to the incorrect valving of the CBR shock for the Hawk that at the limits of use such as high speed corning on a not perfect surface the CBR900 shock will not respond to the surface as it should which could not be fun when the rear wheel decides to upset the party.

              Now does the CBR900 rear shock work better on the Hawk than the stock Hawk rear shock??? Around town it might feel better but at the limit I do not feel that the valving would be correct for the Hawk non-linkage suspension design.

              The aftermarket shock from Ohlins
              The Hawk shock has 47mm of travel
              CBR900RR
              92-95 has 54mm of travel
              96-97 has 60mm of travel
              98-99 has 57mm of travel

              So what does all of this mean as far as travel or stroke of the shock? The Hawk was designed to do the same amount of dampering due to its non-linakge design suspension in a max of 47mm of shock travel where the CBR900RR suspension with linkage is allowed from 54mm to 60mm of shock travel to do the same work becasue of its linkage design.

              So yes the CBR900rr Shock can be made to fit the Hawk frame but in my view and many others it is not properly valved to do the work of the Hawk. Yes, it can be made to fit.

              Below is an image of a CBR900 rear shock and its related linkage from the Ron Ayres web site.
