So, messing about with the Bucket and trying to get the GSXR 600 K1-K3 rear end to fit threw up some interesting findings.
It turns out that the rear sub frame on the Gixxer is the same width as the mounting bolts on the SV (curvy) frame where as the Sv rear sub frame fits aound them. (the Gixxer sub frame is exactly the width of the mounts wider)A small plate on either side of the GSXR sub frame would see them line up perfectly. The only issue that we had was the seat was then slightly too far back.
So a quick cut of the Gixxer sub frame and a spot of ally welding would see them line up just as the SV ones do. Probably a £30 job for someone with a ally welder. This could either be to make it narrower which would cause problems with the panels fitting or just cut the ends and reweld them with a stiffener. Then the whole rear end would just slot on.
The angle and seating position were spot on and a curvy would look really good with the Gixxer tail on. If you use the Gixxer original tail you'd get the whole pillion stuff too. The exhaust also lines up.
If you fancy adding a GSXR race seat unit this is a piece of cake and fits on the standard Curvy frame. You need to cut off about 1cm of the front points of the GSXR unit and the mounting holes line up with the Sv seat mounts.
A small plate underneat the seat unit sees it fit perfectly with one screw on the vertical face behind the seat.
I've cut this original sub frame to save weight but you don't need to cut the standard one.
Sort out a Bracket for the lights or cut the seat unit to fit the standard one and bobs your uncle.
