    Did you use the F2 cush drive instead of the VFR one? That's what I did.

    VFR Cush drive

    I used the F2 cush drive. Which one matches up better, VFR?

    well ive already got the F2 wheels and a new hub and cush drive set....along with the F2 520 sprocket that I'll need since i've already had a 520 conversion done on my bike long ago. I havent started with the mods yet, as i'm still in the massive/ridiculously huge parts collection phase of the project. I will say though that I've been in constant contact with Jamie Dougherty throughout this whole deal, and he has been able to provide an enormous amount of information on this.

    Thats whats up. Okay well i gotta question for u. with the 520 chain conversion did u change out the front sprocket or just keep it stock...or do i have to change the front sprocket with mines.i have the F2 520 rear sprocket already i was just trying to figure if i needed the change the front....i couldnt get a definitive answer.

    I'm pretty sure that the front sprocket has to swap out as well, since the 520 chain is a thicker, heavier chain. both the front and rear sprockets need to be 520 sprockets to accommodate the 520 chain.

    Hello everyone and thanks for the great posts about wheel and fork upgrades. I would like to know if anyone has tried this yet. I have a good 97 GSXR600 that I have decided to part out. Before I get rid of the wheels and forks, has anyone tried adapting those parts to an 86 VFR? I see the beginning of this thread has a VFR with 94 GSXR1100 USD forks (my 600s are conventional) and what looks like the same wheels I have. How much difficulty is involved in swapping a 97 GSXR600 front end onto an 86 VFR700? Thanks for all of your insights.....

    Will,

    In theory, this sounds like a worthy project to try and do, but (a) I really couldn't tell ya if anybody from this forum has tried that particular swap, and (b) since this thread is originally about wheel swaps, to keep things on track with this thread, you might wanna start a new thread on the GXSR front end swap in the Mechanics Garage section and see if anybody who rolls through that section of the forum might have some useful insight.

    That being said, new, one-off, unique projects like that tend to draw a LOT of attention on this board, and you'll surely have a lot of followers if you start that thread and use it to document that kinda swap project (hell, I'd strongly encourage it!!). Good luck!!!

    '88-'89 wheels would be quite rare here in the states as those bikes weren't sold here those two years. I think you'd have to get them from a European wrecker. I've had good luck sourcing stuff from E-Bay UK.

    Considering the premium you would pay for such a rare set of wheels (plus shipping) I'm not sure it would be a cheaper option. Once the busy season settles down a bit I hope to get final tweaks made to the caliper bracket design, then I will be able to offer a bolt-on kit. The price will be in the $275-300 range, FWIW.

    One other thing, a 180 rear tire won't work. The problem is not the swingarm but rather the chain location. Sorry!

    The other problem you may run into, is the UK seller may not. Be willing to ship parts to the US.
    I have found this to be a problem with automotive parts. So contact the seller to make sure he is willing to.

    No, the rear is not an easy fit. I would suggest you not consider the Hurricane front either as it is too narrow to fit a decent tire - that puts you right back in the same position as stock. F2 or F3 parts are the way to go for sure.

    I have a couple of questions about this conversion
    - If you use the CBR forks as this looks the better option, do you have to use the handle bars from a VTR ?
    - Also what is the difference in overall length that you need on the rear shock to gain the ride height to compensate for the 17'' rear wheel.
    My build is about to start and this is on my list.

    This will tell you everything you need to know -> CBR F2 Conversion - Front End


    When I build shocks for this application I include 10mm extra length to compensate for F2 rear wheel.

    I still need more info about the fit up of the front wheel.
    Surely some one has some pics of their modified front wheel to use the stock forks, machining where the discs mount is the easy part but what mods have been done to the hub area and where the speedo drive runs. measurements and pics please!

    I don't think you will find much as this hasn't been a very popular mod. I think mostly because of the machining to the wheel. I've been planning a kit for this swap for some time now but just haven't had the time to focus on it.

    You should double check me on this but I believe you would need to machine 6mm off each side of the rotor mounting bosses. The net result will be that the rotors are the same distance apart as your stock wheel. You will also need to use the VFR700 rotors on the F2 wheel. A new right side spacer and machining to the speedometer drive gear are almost certainly required. I suspect these are very similar (if not identical to) the similar kit we make for the VF500F. The front end of the VFR700 matches more closely to the VF500F, not the bigger models as you might think.

    Thanks Jamie
    Looks like I may have to do some trial and error myself. Not going to machine the disc faces until I can get the spacing worked out. I'll post my results as I go.
