Fitting wider tyres.

[AllanB]

Just go to a 170 - there should be clearance with this - its an available size - the GS1200ss model came out with a 170 rear. No idea why as the rim is the same as Bandit that runs a 180, and lots of 1200ss end up with 180's. The 170 is possibly to quicken the turn a bit.
They are a bit dearer ($10 or so) than the popular and pretty much standard 180.

Nothing wrong with a bit of a chicken strip, but not as much fun as riding a landing strip

I wouldn't do it. You'd turn a sweet handling bike into a pig, but most people say I don't know shit and you should do it anyway.

Jim2 doesn't know shit and you should try it anyway

Nobody on KB or a bike shop knows better than them. Not even me.

Neither does Grub, he can't even wave White flags on the right lap

Just to throw a cat amongst the pigeons, but I seem to remember a young chap by the name of Karl Morgan or something with a 180 or 190 rear tyre fitted to the rear of his SV650 pro twins bike.

Has anyone actually beat Karl in that class this year.............?

Here's a man who's thinking.
Glen Williams is running a 180 I believe, and I know that Karl Morgan is running a 190.
Guess which SV's are leading in their classes. If you can get them cheap, why wouldn't you throw it on and try it?

[johnsv650]

in f3 you can change wheel/rim sizes and then get your 180-190 tyre on the correct tyre rim fitment.
But in pro twins you must use the homologated rim and therefor the correct tyre for that rim as homologated is a 160 tyre even have correct part number 65110-17g00 for those who are building protwins up........
if someone is using a 190 tyre on a 4.5 rim they should have read rule book and dunlpos tyre fitment guide as per sticker on every tyre sold .....
did someone say a protwin rider had a 190 rear and all the others had 160's, isn't there a protest in that class regarding two items..........

Yes but Glens running his on the right sized rim. And I haven't asked him if he's convinced with it.

Never met Karl but he sounds like he's a lateral thinker or has some good people helping him out.

[FROSTY:Me]

I rode Glens bike and was really impressed by how well it handled.
But a factory SVrim wont take a 180 so it must have a cibber rim

[HornetBoy]

Im pretty sure sv's run the same size width rear rim as late model katana 600 and 750's. (4.5")

if this is the case then you can get a 180 on their but the bigger you go the less tread is in contact with the road and this means more chance of hydroplaning in the wet or loose gravel.

also bad wear angles as the middle is pinched to fit on a smaller rim width than oem, so i could only assume this would hinder turn in stability.

but what do i know

[n0regret5]

wide tyres add street cred..you'd be partway to a mean streetfighter! as for the handling issue..with something putting out less than 100bhp at the wheel, its more likely to fuck your handling in and out of corners, due to the effects it'd have on your steering geometry (bikes gonna be on an odd angle when you put your knee down)..

but i say if you can find a way to do it, and affordably, go for it. just make sure you get REAL used to it before taking the old girl back onto a track!!

[RidingHard]

IMHO as "phat" as big dog tyres look on the rear (and they look pritty damn cool), and although it may fit, stick with manufacturers guidelines or you may be pissing away your money. I want to fit a bigger rear to my ZX6R so I'm looking into this at the mo too.....

So do it and tell us what happens!

If there is a protest in this calss, based on a rider using a non reccomended! Size tyre- I would personelly call the person who laid the protest a real WANKER

What a pathetic thing to protest about

[White trash]

Same could be said about whoever protested Bruce Ansteys use of a carbon front mudguard two seasons ago.

Or a rider riding without a front guard fitted.

Where did that happen man?

Shaun --I think whats being "hinted" at is that the factory SV650 rim barely fits a 160 -therefor how could a 180 possibly fit.
Or on plain english-pro twins rules say you must run FACTORY rims
If someone has a 180 tyre the rim cannot be factory

On the subject of fitting the Supersport tyres to SV rims I believe this to be a good thing if its not going to be turned into an issue and it actually works well.

Its good for Supersport riders as they have a market to onsell their slightly worn tyres to. And its great for racers on lower budgets as they can have good rubber without paying high prices.

My experience when buying new tyres has been that the 180s are cheaper than the 160s probably becuase they are produced in much larger numbers.

As for the rider that started doing it. possibly cost and availability may have been the initial reason. Maybe a bike will be better with a 160 but riders should be free to make up their own minds as to what they wish to run.
Unless of course theres a safety issue here.

One flag, one lap, two bikes, 6 months ago - get over it. Apart from that, it was the lap couter person that called the flag, I just wave the thing.
