Tyre size -- How does it affect ride?

i understand everything your saying as the wifes uncle is also very well none being Clif holland from wylie and holland race team so am lucky to be able to call or get advise from alot of top racing and development teams and they have all said the same thing ( BAD IDEA )... also having tryed this on the track now it really dos not make sence to put an over size boots on a rim.

be it or not the sv650 was/is built to a low budget so it will never be a really grate bike, but then all things can be improved. and maybe comes down to your own riding style. nothing is set in stone also i didnt see much diff running the 180 on stock rims i did still enjoy the day. having tryed both 120/160 & 120/180 on the same day on the same bike. in 2 diff types of tyre i would say just stick to the 120/160 unless you REALLY and i mean REALLY! want that 180 on the back then just change the rear rim to take a 180 boot..

Yes. I know I'm being very bad,and to be fair I do have a 5.5 inch rim that I'm looking at mounting .but as the tread had gone on my old hoop I thought I'd give it a go
I'll sit in the naughty corner for the rest of the morning .
Oh and it does decrease its mpg range is now 140,was 150.but might be down to the fact I'm gasing harder through the twisties?

In practice, all it will do is allow the rear to tansmit traction that bit better getting on the gas in a straight line. But you're not talking 180 brake which needs smearing into the tarmac, and you will sacrifice ease of turn in.

Not a massive difference, conjecture like this help much.

TWF racing sell kit to fit 06> GSXR rim to either curvy or pointy. This lets you try tyre without a large weight penalty. Then you have correct 5.5 for 180 tyre.

Getting hold of the right wheel at sensible price and then getting it machined is harder than youd think

Nothing to do with conjecture.

Generally speaking, mismatching section and rim size will have an adverse effect on handling, because profile will become distorted. This is not just my view btw, as previously stated.

On a more personal level, years ago I picked up a bike with an oversize rear on it, and surprise surprise, once this was remedied the bike felt twice as agile. anyone can fit what they like, but if you want to know what the manufacturers stance is, I think its been fairly described above.

You could fit a 160/70/17 on the rear which would give more rubber on the ground without the pinch problems on a narrow wheel with 170/180 tyre widths.

Fair enough if you're talking specifically about wrong rim size. Sounded like you were on about fitting any 180, regardless of matching wheel.
