RE: Bigger Rear Tire?
Only problem with running a fatter tyre on the stock rim is......
The extra flex needed to seat the tyre gives a slightly smaller contact patch on the road. On a car this wouldnt pose much of a problem, but as bikes have a tiny contact patch anyway, it is much more noticable. I really dont see the reason for a fatter back tyre, except looks. I have never ran a larger back tyre so I dont know how much different the bike handles, but in theory, you lose grip.

Ghost1Rider, gmejr has an 88 which comes stock with a 3.5" rear rim (same size asyour front) so adding a 90 or newer lets us run a 180 section tire which gives us way more grip. if you want more info look in my profile and read my past posts, all the info you need to do the upgrade is in them... good luck.

Unless you want to spend alittle money and turn some wrenches on your own. I would stay with what stock size is for the bike. Now if you're like me and can't leave anything alone. You can swap out your rims for a '90 and newer model cbr1000f so you can fit more common size tires (120/70front and 180/55rear) The costs depends on how much you get your parts for. But unless you're like me it'll costs you an estimated minumum of $500 to do the swaps. It'd be alot cheaper to get the best tires you can buy for the stock size. If you're wanting the looks of a wider tire... I'm still waiting to see a hurricane with a widened swingarm and a 240series tire on it, all stretched out and chromed. Ayyyy...yyyeeessss... Oh! Sorry dreaming again! Even if you did that it would handle like crap. Now... I'm not trying to tell anyone not to do the swap. Just putting the thought in their heads.. "Is it feasible in the real world aspects?? Ah, screw real world. I just want it to be kick ****!"
Oh. in case any one wants a pick of the wider rim on the older bike.I'll post one of mine. (Yes I know it's been posted before. I just like posting pics!

RE: Bigger Rear Tire?
Hey guys,
Last time I saw this post it was way longer and seemed to have a lot of debate as to how to fit a later rim to an 87 or 88 CBR1000F. For everyones information I just fitted an 89 rim to my 87 last weekend. Twas an absolute breeze!
Did it tight *** style.Mail ordereda bare rim from from a bike wrecker cost me AU $190. Got a new 190/50/17 Maxxis tyre fitted for AU $217. Used the 87 cush drive and shortened the spacer between the bearings from 26mm to 19mm (properely in a lathe). Added something like 6mm spacer between wheel and brake mount to get brake mount in right spot for original 87 disc. Used the 87 brake caliper. Put a smooth raduis bend in the stock brake locator rod using two bricks and a piece of 6x4. I cut the inner guard off the chain guard and refitted the chain guard.
Looks fat!
Yes I know the 190 is supposed to have a 6" rim and that the tyre companies recommend 180 for 5.5"........perfect handling.....blah blah blah.
Refer to above statement for my response.
