Rear SubFrame

Ok so the rear of the ol' girl is well out of shape, she needs to hit the gym and tighten up that fat arse! the fairing is ok but a little large for me, i would like to change this for something narrower/thinner. The rear light unit is massive and fair play its great for visability purposes but not the most sporty looking unit, plus there must be a fair amount of weight to be saved from changing this. The undertray is huge and heavy. Also a big dislike with how the bike is currently is the combined seat unit. It was great for touring with as it was really comfy for long periods and great comfort for the pillion too but..... It looks dated, its massive, really heavy, and just doesnt look the part for a sports bike, two separate seats is the way forward.

So stripped to its bones, first things first the subframe needs to be changed. Initially i wanted to fabricate my own custom subframe but im going to save that for a future project as i dont currently have the time.
Original subframe weighing in at 3.3kg


After doing some measurements, and looking at different subframes out there, i found that a CBR600rr 03+ model subframe would fit straight to the vfr frame on the bottom mounts, and i really like the style of it too especially if i was to go with a cbr600rr rear fairing this would be perfect. All i would have to do is make up some brackets to mount it at the top fixing points.


One CBR600rr subframe purchased from ebay, weighing in at 2.7kg - a nice little weight saving (every little counts right?)




Painted Black




Machined some brackets out of high tensile aluminium, measured length to give desired subframe angle.
Brackets on and match the frame to the subframe perfectly
Subframe... salt and peppered! :)
