Will a larger rear rim, say 5.5 inch, with a 180 section tyre on it fit in the standard swing arm, or will it rub?

It will clear.....Just!!
Ps i have an r1 wheel in mine, had the spacers made up....
I have got a YZF swing arm on the way, which means potentially new spacers
, so there may be some going if you know what i mean...

Philk,
OK, spacers could be useful..

Plenty of room for the 5.50 180. The YZF750 wheel bolts on with bearings sized to the hub / TRX axle shaft and proper spacers (you can use the TRX cush drive hub). You will also need to either stack your countershaft sprocket (I used a thinner, aftermarket job), flip the rear sprocket around or have some milled off the hub for a 3 mm offset change in chain line.

Does the original TRX brake disc fit on the YZF wheel? And how bout the caliper, does it line up properly?

Yes, same disk. I can't remember offhand how I modded my spacers but I use the stock carrier and rear caliper (to be changed in the future for something that doesn't weigh 10kg...).

Funny you should talk about 180 rears.When I brought mine second hand it had a 180 fitted to the standard rim . It was only when I was doing a day at P Island and met anotherTRX rider that I found out 160 was standard . I use 160 to 170 and it is easier to turn. I know 180 has more tyre options but for basic standard bike I wouldn't go past present tyres . 180's look fat thats why some go for them , those that do track days may get better value with 180's but on the road maybe not . I see most tyres are replaced with the centre bald and the sides like new WHAT A WASTE

Bob,
One of the TRX's I bought for parts had a 170/55 or maybe 170/60 rear on a standard rim, which seem to fit fine.
Trouble with a 180 on the standard 5" rim is the tyre must have to deform from it's intended shape to fit the narrower rim?

You won't get any use out of a 180 on a 5" rim, at least not it's potential advantages. And yes, a standard size is fine for the street. But if you spend much time on the track, you will find a better selection of tires and traction like you've never experienced. Not only that, but it gives you a few extra millimeters of ground clearance when banked over.
