As the title asks I need to know if this will work on the track ,what are the positives and what are the negatives
So anyone who has tried this ,tell me about it please

Cheers Pete

Depending on manufacturer you may have problems with the wheel hitting the mudguard, especially under high fork compression

I used one once and it hit the radaitor guard under heavy braking.

You might get away with it, you might not.

Cheers would I notice any difference to standard 120/60/17 on the track

i would leave wel alone,as stickshift and neo say's it will foul parts under heavy braking.

it will be a tight fit clearing the mudguard,if it does.

It all depends on the tyre and how you ride.

The only reason i'd personally use a 120/70/17 is if there was a specific tyre I wanted to use that I couldn't get in standard profile, is this the case?

If so then it might be feasible to move / adjust whatever catches. If not i'd stick to standard and spend the money on improving other part(s) of the bike.

i have heard of plenty of racers using this tyre without any problems. now if you have standard fork springs you are gonna have a problem, but if you are taking it to track, front and rear suspension should be your first mods anyhows. and for track, suspension is usually set stiffer.

mudguard from what i have been told is a problem, but all you have to do there is some longer bolts and stick plenty of washer (to act as spacers). not yet tried this, but makes sense.

i will be using this tyre size for track days this year, as i can get cheap ex racers that size.

if you have the likes of a fork uprate kit from rick oliver on the site like myself, in addition he also does a anti-bottoming out kit for the forks which may be useful for you even for extra piece of mind.

I had one for a bit, didn't get on with it and it fouled my mudguard.. Got some scrapes on the top of the v piece..so got scared..

120/60 for me..

Thanks guys ,I do have some track tyres in that size hence my query
Im gonna run with 090 front and back standard sizes and see how I get on with the bike before any more mods
Thanks again
