chicken strip difference front and rear

Forum Sponsor

I just spent a week at the Deals Gap riding all the crazy twisty roads, and my front tire has almost no chicken strips, but my back still has 1cm. It's confusing the hell out of me

Killerkeith had the same problem, and the guys said it's likely a result of him not hanging off the bike enough, and thus, asking for more traction out of the front tire as it was leaned over more. Their concern was that he was close to overloading it, and that he would lose it if he pushed harder. The solution was to hang off more.

This is just what I overheard. I defer to those with more experience.

I was pretty hanged off, didn't seem to make a difference. Twostroke said I was actually backing it into a few corners, maybe I'm just too awesome for my tires

Bahahahaha! That's probably a bit true, considering you're on bias-ply pieces of crap. I'm telling you girl, bigger/better bike! At least ones with tires you can trust!

Both statements are wrong

I hope those tires didn't come with the bike, lol

Fair enough, but care to correct us then? We're eager-to-learn noobs.

In regards to the original question, bigger chicken strips in the front is because the load of the engine on the rear tire deflects it more, actually allowing the tire to fold over onto the portion. The front is dependent on one thing - how hard you crank through the corners.

In regards to Amason's comment, More aggressive riders tend to push harder into turns, or brake deeper, which also deflects the front. Tire profile also has to do with the size of the front chicken strips. It could also be that you are braking very aggressively into the turns and not accelerating through the exit, it can be many things but not the amount of hanging from the bike - however, I have been known to be wrong a few times.

Here calculate your lean angle

two stroke doesn't know what backing it in looks like..

+1.

It can also depend on tire profiles. I personally dont like the "flat" profile of Bridgestone Battlax tires because you get on the rear edge real quick! My guess there is that they also overhand the tire wall a little and allow for deformation when you go "beyond the limit".

With Pirellis Diablos 3s however I find once I was juuuust nicking the edge of the rear (no chicken stripes) I had about 5mm left on the front. Both have a pretty steep profile which I like. By the time I got good balling up on my front tire and got rid of the front stripes, my rear was good and well being used up, balling up and pealing about 2cm from the edges.

In that case I noticed by my wear pattern that when the front chicken stripes were gone, I was not getting on the power right at the edge of the rear. I probably could have gotten on the power a little sooner out of the turn to be honest.

What I am saying is, even though I had balling on the rear tire edge, there was another pattern 2.5cm away from the edge (different than balling), which is pealing from getting on the power while leaned over, and as I said I felt I could get a little more out of the tire.

So to recap....rear and front don't always wear exactly the same. Rear has a greater contact patch and can lean further than you think! Balling pattern is different than acceleration pattern and there is more to it than straight forward leaning. Also trail breaking the front tire into turns will produce more balling on the front tire. If you baby it into a turn but lean a lot, you will get some scuffing on the front edges but there is plenty more capacity in the tire to brake hard into the turn, gradually applying less brake with greater lean, etc. This will heat the rubber, make it extra grippy and push that pealing rubber out the the sides (edges) while you proceed into the turn.

But for now, rest assured you are doing fine.

Just remember, don't concern yourself with chicken stripes on the street!!!!! Max tire pressure + tires which are not heated to proper operating temps + not even maximum lean = possible slip!!!! On the track, dropped pressure and heated tires feel like rails at max lean!!!!

Here's a crappy vid i did at tmp a while back.Recip does a bit of backing it in on his Honda Motard.[video=youtube;WzSBVpIsCYs]http://www.youtube.com/watch?v=WzSBVpIsCYs[/video]

I go too hard into corners and not hard enough on the gas on the way out...it's still my biggest problem.

Body positioning, not just hanging off, but where you weight the bike (front vs. rear), and tire pressure variances can also play a role in how your chicken strips appear. Remember, that when the bik eis moving, and you turn into a corner, the tire's contact patch profile will no longer look like it does when sitting on your stands. The tire will deforem and the carcass will stretch and twist, dependant on the forces acting upon it when turning, accelerating, and braking.

Deals Gap and other roads going into the hills tend to have additional camber engineered into them. This will keep the tire up more onto its centre & mid-portion and away from the edge. This provides a higher safety margin to road users as opposed to a similar level-grade constructed road. That may explain part of OP's situation.

Also, going downhill on steep grades with turns in them will put additional load on the front, allowing you to get closer to the edge. Going uphill, you would get less close to edge with the front & more with the rear.
