Hi all, Just trying to sort out which bike I would like to get and so far Im looking to choose the Honda CBR 600, a 1990 model due to cost to buy them plus I can get it on classic insurance which is pennies for an 18 year old!
I intend to fit
- F4i Front Fairing
- 600rr Rear seat
- F4i Digital Dash
- Braided hoses
- Race pads ( just to say I have them really lol)
- Leovince exhaust or copy of it as I have the Decal for them
What I am looking at is replacing the rear wheel/ subframe with a more lower profile wheel, and perhaps a little wider, more like modern superbikes??
Can anyone tell me whether I can fit, even a F4i or a 600RR rear wheel and subframe??
What about the front wheel, can I fit the more modern front wheel too??

You'e going to have a lot of trouble putting those parts on a F1/Hurricane frame. Lots of custom work required. I don't think much wider a tire than a 150/160 section will fit in the stock swingarm. You're talking about a 180 or wider, and for that you'll need custom, or custom modified swingarm. 180 won't fit the stcok F1 wheels so you'll have a mismatched wheelset.
For the bodywork mods you mention, you're probably doing yourself a favor by looking at at least an F2 as a starting point - the F4 fairings swaps are pretty well documented around here, a 180 tire will fit in the stock swingarm, although it doesn't fit the stock rear wheel very well. a 900RR rear wheel solves that problem, and still matches the front wheel.

Cheers for that mate, Just looked on Ebay and I can pick a rear and even a front wheel for not alot of money! So Thats another problem I have sorted out, the 91 600 CBR is looking more and more likely rather than a 400 import
Right onto to finding a decent 600 that has scruffy fairing but otherwise good
The F3 95-98 has a 5" rear rim which will take up to about 170 width, some have put 180's on but tyre manufacturer's don't recommend it. The front wheel will take a modern 120 tyre anyway. If I was you I'd obtain a used tyre of the size you want to use and see how it fits - does it clear ok?
Things to consider: A 180 width tyre is best fitted to a 5.5" rim and a 190 on a 6". If you fit a wide tyre to a small rim you change the profile from what it was designed to be and the bike may behave funny. You will also be jacking the back up which is probably ok on the 600F if the geometry hasn't already been changed. The bike does not require more than a 160 and it will not corner any faster due to a wider tyre, but ... being able to run a 180 will allow you to use the latest, grippier, sports tyres. However you may find some sports tyres available in a 160. Running full on sports tyres on the road doesn't really give you much benefit, in fact when the weather is cold or wet they are often poorer performing than some of the top touring tyres such as Dunlop Roadsmart. I'd go as far as to say I found a Pirelli Diablo Rosso Corso just plain scary on a 1000 bike at 5 deg C and damp roads! The same tyre was fine above this temp damp or dry. The reason is that modern, grippy, sports tyres need to heat up to work correctly - that is also harder to achieve the bigger the tyre. It can be difficult on a 1 litre sports bike in anything other than warm and dry let alone a lower powered 600.
If you just want it for looks then go for it but beware. If you are hoping to improve cornering & grip I wouldn't bother, it may get worse. Just get a modern, quality touring tyre like Dunlop Roadsmart, Michelin Pilot Road 3, Bridgestone BT023
