I've got a zxr 750 H1 haven't had it long. I'm noticing that the while I'm wearing the back tyre right to the edges the front still has good sized chicken strips (10mm). Is this normal? - I've checked that the tyres are the right size 120/70/17 front 170/60/17 rear.

Both are due for replacement too so if anyones got a half worn set they want to sell me I'd be keen.

Thanks

Yes,most road tyres seem to be made so you run off the rear before the front :niceone:

Like Death says, it's by design.

Whether it be for safety, or to allow the bike to drop in to the corner faster, the shape of the front tyre is way different to the rear. The front tyre is made much steeper, and if you took them both off of the bike and rolled them to the edge of the tread, it would be obvious that the front tyre is at a much flatter angle (to the horizontal) than the rear tyre is...

hence, when you're riding the rear will reach its limit, and the front, at the same lean angle, will have rubber left to lean farther (given the chance).

Some tossers would say that you're just not leaning far enough.... They are the ones with a long list of crashed bikes blaming road conditions etc. So long as you are getting thru the corners efficiently and quickly enough for you then don't worry about the unused portions of tyre you have left. Only a few here really judge others by the size of the chicken strips and they usually have the biggest ones but have a "mate" on a GSZXRCBRCBRRRSP who can get all the way to the edge but he's in hospital right now because a tractor pulled out on him when he was going a round a corner at warp speed and he couldn't avoid it! But it was the tractors fault of course!. Whoppee for them.

yep its all good, the 120/70 front you'll never scuff to the edge of the tread, especially on the road. you can scrub up the rear to zero C/S and the front will still be batting for tegal.

I'd say dont listen to a word TWR sez, his tyres are square and bald in the middle.

Actually it is caused by a combination of incorrect suspension settings, wrong tyre pressures (for the current riding style) and standard fear for life. :yes:
What is probibly happening is you are going into the corners much slower than you are comming out of them :yes: . This is natural and safe :2thumbsup . AS you get on the gas the rear suspension compresses and the tyre deforms slightly giving the appearance of you leaning to the edge of the tread. On the front most people do not want to go in that hot (who can blaim them) therefor do not compress the suspension and deform the tyre that much.
If you are worried about them you can piss around with your suspension settings and ride heights to get a more even distribution but if your bike appears to be handling fine why bother. Just enjoy. :rockon:
The only people i know that can safely run both tyres to the edge are racers, ex racers and the soon to be departed............
