Machine shops should be able to make up whatever size you need. since you're going to need the hub carrier machined anyway, get them to build the spacers - just needs to be some decent cold-rolled steel.

what he said... ... the place you take the hub to get lathed down will use the same machine to make the spacers so you should be able to do it all in one shot.

when you get the guy to do it... post up the specs so I can get mine done as well and for others looking to do the swap.

There are 3 drawings in KokoTL100r's thread. Two are spacers. Here they are. Measurements are metric. He also has a picture of the hub from behind and above that shows the finished hub. Actually the link that has the drawings is this: http://racebiketuning.com/cbr600f2-e...ort-race-bike/

FNQuickF2,

You do not have a 5.5 rear rim, you're measuring it wrong. Measure your front that way and you'll see it's bigger than 3.5.

To measure the rim you need the tyre off and measure on the inside between the sidewalls where the tyre bead sits.

BTW, the guy who fitted the fireblade rim must have also modified the brake caliper mount. I've decided not to bother on mine and fit an AP style mini caliper with a custom floating bracket. A mate of mine fitted honda RS125 rims to his MZ and the floating rear caliper made a huge difference to the brake drag compared to his old setup.

I fitted a F4i rear rim to my 93 f2 and all i had to do was machine the original spacer down so it fit the F4i rim. I've got about 10-15mm clearance either side and retained everything from the original setup.

...and your chain lines up perfectly? I'd be surprised if it does.

Hy, Im having a slight problem here with bearings!
So, there are this dust seal. If you machine down the F2 sprocket holder, then theres no more place for it!!! So, what to do? Leave the bearing without it?
So, any of you have done the rim swap yet? can someone please provide me with more info, than just Kokos? There are some issues with the spacers too, cause, I cant understand those drawings. they just dont make any sense!!!!! The right side spacer is same as the original, bet left side....... is just not understandable..
I really need help!

no dust seals, there isnt room. My is a race bike so i'd run without dust seals even if they did fit.

This is what it looks like when done:

CBR 600 F2 Thunderbike: Sprocket carrier spacer finished

Though I measured it all up from scratch, some of those measurements from koko weren't quite right for my bike. To be fair his drawings are quite clear. I made the sprocket carrier spacer from one of the old bearings then machined down the sprocket carrier on the lathe. There was no way the old brake mount was going to fit so I made up a new bracket and spacers for the brake side. Look through the blog, (almost) all the measurements are there.
