110 70 17 front tyre

All right. Lets stop it.  I think my English is not good enough yet...

but it's been fun. Yours is better than most, believe me.

Fair enough but still your using a 3.5" tyre on a 3" rim so at best its not got the profile that Bridgestone Michelin etc intended.

10mm different, 5mm per side. 4,33" as opposed to 4,72" nominally. Fits quite happily on there and means that you still have tread when the rear runs out, I ride on the front so it's good for me. I expect fitting the occasional 190 on the rear of my other bike instead of the 180 is dodgy too    The profile is slightly pulled but so what, not excessive, not dangerous, helps handling, more rubber on road too. Get a grip for pitys sake. I suppose my Renthalls, bar end mirrors, fazer 1000 rear caliper, disc of a thundercat, screen bolts, perch bolts and so on aren't good as Yamaha didn't fit them, goodness knows about the blue flame and stainless downpipes, and oh god the main stand isn't fitted and the rear is jacked up too. It's a hanging for sure 

Hang on i'm  not  saying if you modify your bike you'll be killed to death horribly or anything just saying the profiles not whats intended. I used a 140 instead of 130 rear on my cb500 because it's all sticky and cheap used Bt090's come in. Oh and my Nitron shock, zx6rm/c, K tech fork springs, goldspots aren't what Yamaha put on, neither are the clip on's or Jap rearsets that are on the way....

Oh I know that but the implication is you can pick and choose which parts you feel are for the better and which parts for the worse and while in the best of intentions, poor advice is worse than no advice at the end of the day.

[thom_1991]

It's not poor advice it's a statement of fact. 120 tyre on a 110 rim changes it's profile.

yes it does a little, so what? It's not dangerous. Any different size tyre that standard will pull or push the profile a little depending on the make of tyre too. The implication from some is that it's dangerous to fit the 120 on the standard rim and it just is not.

Lumpy i think your thinking is way out riders do not hang off their bikes to save tyres never never ever....

[topgun44]

wow this is getting deep so some say you can and some say not

I think that just lumpy says you can...

An experienced guy I trust encouraged me to fit 120 tyre up front. They are a lot easier to find in Serbia. I didn't listen to him. Couldn't forgive myself if anything happened in a corner with such a tyre. That thundercat 400 fron whole wheel exchange looks tempting though!

[Lumpy]

Lumpy i think your thinking is way out riders do not hang off their bikes to save tyres never never ever....

and nor did I say or infer that. Not a politician are you? Racers hang off so more of the tyre is on the road / track and keeping the bike more upright due to the slip angles and lateral forces involved etc. , they don't ride to the edges if they can help it. One of the replies earlier stated that having 10mm of rubber left is pointless, hence the analogy. Hope this clears thing up on that one.

120/70 front & 180/55 back for 2,5 years with no problems.
VERY steady in highway with 160-180 km but a little slow for turning (i dont push it to the edge).
I dont know the difference with 110 front - 160 back because i bought the bike with these tyres.
Sorry for my bad english

nothing wrong with your English and much more intelligent than most of the replies.

2.5 years with the same tyres he got the bike?! He must be riding to the edge, really feeling it!

I thought he meant the same configuaration not the same tyres, there again, my tyres on the Bird seem to last rather a long time under that bike cover

The correct move is to put a wheel from FZR400RR which is identical to the FZS600 and behind a wheel of YZF1000TUNDERACE and so you can enjoy a much better grip.

That way they can find and widest range of tires 120 and 180.

FAF. If it's identical what is the point    although it's not identical is it 
 
Why much better grip though, if the compound is the same the grip will be the same.

[petani]

The dimensions of these wheels is 3.50CH17 and 5.5CH17 while the fzs600 is 3.00CH17 5.00CH17 and thus not sit well the 120 and 180 joints.
I had for 5 years and led them in the street and truck days ......  really can believe me that the difference was great.

So you have tried it? Great!

Does the speedo fit spot on?

Bearings, axle? Can I use them from FZS, or I have to get FZR400 axle and bearings?

160 rear is common, but 110 is a bit harder to find, so I'd look for front wheel swap.

[Lumpy]

I expect it may have been but as mine is a commuter with occasional big bike chasing, I'm content with what I have. Not keen on the 023s though still prefer the Dunplops Roadsmarts wet and dry.

Yes all the same for the front wheel. Only difference is in rear wheel  and you have to made  two adapters to use the axis of the FZS.

The problem existed in Greece, where I can not  find 110 front rubber and so began to Looking How can I correct a 120.

Can you describe the adapters and what model the Thunderace's rim is?
I put recently a 3.5 rim from a TRX850, same model as the FZR (F-52).

Thanks

[petani]

Excuse me my fried but  I've sold the rims. But remember that the bearings of the YZF is 28 mm thickness and FZS 20mm. So I made adapters with external diameter 28 and 20 hole like that of the photo.
The model is 2000 YZF 1000 THUNDERACE

[Motorbreath]

Thanks!
