Front tyre chicken strips

[Tim..]

After riding a massive tourer for well over a year I sold it and bought a naked sportsbike (BMW F800S).

Went out for a ride to my old favourite knee down roundabout to see how rusty i was (and i was rather bad, felt a bloody mile away ).

When i got home after a good run round some twisties I was glad to see the strips gone from the back, but the front tyre still had massive strips, whats this due to? Bad corner entry speed?

Might get some pics up later.

Not necessarily. Just the profile. Different makes/models, etc


I didn't have any chicken strips on front or rear on the NC30, even to the point that I was really ragging it round corners and you could see it on the tyres!


On the Hornet however I could never get the front strips off, yet the rear was truely ragged.


I'm pretty sure Big_Ham when he had a trackday Hornet he couldn't get the front strips away either, and he was going slow. I think the case is by the time you get to the edge of the front tyre on the Hornets, you will have run out of tyre on the rear, though I may be wrong...



I've heard most people will have trouble getting rid of the front strips of supercorsa tyres because that profile is just that steep!

Found it differs from bike to bike and tyre profile to profile.

Normally, I tend to get rid of the back's strips easier than the front. My NC30 wears evenly, but my ER6 had none on the front but a couple of mm on the back...

Not that it should matter anyway, it's not always a sole reflection on how quickly a bike's been cornering.

I didn't think it was possible to get rid of chicken strips on the front, due to the profile of the tyre.

Think it depends how hard your counter steering too. The rake angle of the fork means that the more you turn the bars, the more the houlder of the tyre will be in contact with the road, rather than the centre of the tyre. Would have expected this to be even more so when the bike is leant right over.

Aha.

I think it's good to have atleast a little bit of unused rubber. Means you've got something in reserve if things go tits up.

No bike i've ever owned has had front tire chicken strips even if i've had them on the back. As others have said it is probably just due to the profile of the tire along with the steering head angle when cornering. Faster corners will need less steering lock and probably use more of the front tires surface.

On the Hornet I've had no rear strips and a good 10mm on the front, the the RSV I've none on either tyre, and on the steely CBR 600 I've got none on the front but 15mm or so on the rear (160 profile)

[Frost]

Check that the tire pressure isn't too high or that the suspension isn't too soft. Either of these would cause the tire to deform less due to load at turn in.

[Acemastr]

[Alex A]

Pretty much always end up with 10mm or so strips on the front tyre even with the rear tyre torn up right to the edge. Tend to run Racetecs these days and it's pretty much the same story with other riders I've seen on the same tyres.

Really it should depend on the profile of the tyres and the geometry of the bike as to how much of the front profile you will use in relation to the back for a certain angle of lean.

When you lean a bike over, the back wheel is still in line wit the bike, the front is twisted at whatever angle th ebars are pointing, right?
If you are leaned right over in fast bends, then the steering angle is minimal, so the fornt and rear tyres will show similar amounts of lean angle.
If you are cranked over NOT so far then you get chicken strips.
BUT if you twiost the bars, so the front is angled in more, the front will rub more than the rear.
SO, if you are leaving wider strips on the front, means that YOUR cornering is wider faster bends not dumping it low in the slow-speed sruff.
Would alsoi expect that the the rubber would show 'feathering' the sort of curved wear marks from the inside radisu being that much smaller than the outer, and the 'scrub' on the tyre from being forced to eform that much at high load, rather than just worn to that angle.
Its ALL brevado and Bull-Shit for the mot part, when it comes to talking wear patterns.
feathering says more thnan chicken strips though.
High speeds cause feathers, chicken strips just say how far over you tilt.
People get obsessed with thit though, like getting your knee down.
Just enjoy the bludy ride!
Who cares how brave you are!
End of the day, what counts is getting to the end of the course!

Cheers Teflon-Mike, all of that makes sense, and you were right about my tyre wear (feathering etc).

I'm trying to be a rossi or even fixate on trying to get my knee down. Just wanted to understand more about how the bike/me is behaving to try and generally improve my riding style/skill.

Oh and the Spell Check button is your friend .

On my f650 its the complete opposite to my old S4.
I've got about 2mm on the front and about 10mm on the back, i guess thats funny sized semi-knobbly tyres for you.

[Teflon-Mike]

[SamJL]

I don't have any strips on my front tyre, but I tend to push the front quite hard, which is probably going to bite me one day!

I ride with a friend, were about as quick as each other, same tyres and he has some strips on the front, but not the back, I think Im just a bit harder on the front!
