    Front tyre chicken strips depend on the front geometry which is your current setup with you onboard are at the maximum lean angle. To put it simply If you increase forks angle comparing to what you have now (measured from vertical line) lets say you go from 23.5 to 24.5 degrees you will get much smaller chicken strips in the front (and probably oversteer as unwanted bonus depending on the trail), if you decrease forks angle, for example 25.5 to 24 degrees (and maybe understeer as unwanted bonus depending on the trail), then you will get much bigger chicken strips in the front. The reason for that is when you in the corner, front tyre is always leaning more than the rear into the direction of the turn and the reason to that - forks angle. You may keep your motorcycle vertical and turn the steering to the side and then look at what you got - rear tire vertical, front tyre leaned to the direction of the turn. Imagine impossible condition - 90 degree forks angle (forks parallel to the ground) then turning the steering will cause zero wheel turning around vertical axis, wheel will just lean to the left and to the right. On the other hand every manufacturer design their tire profiles with this effect in mind, but it is unknown what geometry they had in mind while designing the tire exactly, however for safety reasons and taking in account that some bikes (zx-10r from 2011, RSV4, etc..) have very lean forks angle, - front tyre will be made with safety margin so even on these bikes you would not run off the edge of the front tire. Example - same rider taking same turns at the same speed on RSV4 will have smaller front chicken strips comparing to him doing it on stock S1000RR). Now it is obvious that you can choose tires with right profile for your bike, those which were designed to fit your front geometry closer - this will give you more grip and confidence both front and rear. Sure all above is only valid if you have adequate spring rate, forks oil level, correct swingarm angle, correct shock linkage rate and progression, sag is set right and damping is adequate, wheelbase is correct for rider and bike weight distribution, over vise you may end up with all sorts of anomalies for example you going straight as on sportbike which, geometry wise, suddenly becomes a chopper at the apex. Every setup consists of repetitive iterations, and if you do it right then you reaching towards better setup, however at the same time you will be riding faster with each correct iteration which adds another factor to the "next step right setup" definition.

    Great advice, sir!
    Your comment at 00:45 is especially encouraging because there seems to be a lot of pressure from my riding community to abide on the rear tire's bleeding edge while turning. I am comfortable leaning my bike, but have yet to determine why that much lean is necessary off-track. Regarding the matter of front tire chicken strips, I appreciate your suggestion to not worry about it and focus on skill-building.

    I made a big mistake when racing in raising the forks 8mm through the yokes/trees...damn near fold in half at a slow 2nd gear corner! Put it back to stock then increased it 2mm at a time eventually ending up with 4mm and a turn or two of preload to support the changed weight bias.

    If you're counter leaning at all on the streets you're not gonna get rid of your chicken strips on a bike with good tire pressure and proper suspension set up. If you are some how you're on your way to a coffin.

    Should I be concerned about the setup on my bike, since I have no chicken strips front or rear? I have an RC51 using Pirelli Superbike Pros on the track, and just finished a set of PP2CT's on the street. Same deal with both types of tire.

      Due to the pressures you used, the profile gave you more contact patch, hence lower pressures at the track.

    • @catalystreactionsbw
      @catalystreactionsbw  8 лет назад +6

      Not necessarily based on steering head, rake and trail and fork length. There are several models that needs the forks slightly higher than stock for stability, and if you work in small increments of 2mm or so at a time, you will find the fork placement location that gives you the steering you need.

    Hi Dave, I have an Aprilia rsv mele factory 05, I put a 200 tyre in the rear which pushed up rear little bit, it turns in really quickly and I like it. I have 4 rings showing out of the top yolk on the forks, should I compensate it by dropping it down to three because the 200 tyre lifted the rear, or should I try it and if the tyre wear and the handling is good leave it as it is?
    Sorry if I posted thus in wrong place. All advice would be greatly appreciated.
    Many thanks, Richard.

    • @catalystreactionsbw
      @catalystreactionsbw  6 лет назад +3

      Run it as is for a while to get used to it. Then as a test, add several turns of preload to simulate changing to 3 rings to see how turn in (no brakes!) changes and if you like it.

    I experience the opposite. I have a 06 SV650S with Dunlop Q3+, 160/60 in the back and a 120/60 in the front. I run 31/33 for pressures(cold). I have re-sprung the front for my weight and have installed a rear shock. Everything suspension setup correctly. I have about 3/4 of an inch of strips in the rear but almost to the edge on the front. The Last thing I want is the front end to wash out, Should I just not worry about it or do I have something wrong?

    • @catalystreactionsbw
      @catalystreactionsbw  4 года назад +1

      I would change to a 120/70 to give yourself more lean and safety. Measure the difference in circumference and simply change geometry via fork position.

    Dave, I'm running Bridgestone s21's on a 750 k7 and I'm rolling of the edge on the rear tyre, yet have 5-6mm of tyre left to use on the front. Should I put a 190/55 on the rear or look at chassis/suspension/tyre pressures first? Pressures are 32 front 34 rear

    • @catalystreactionsbw
      @catalystreactionsbw  4 года назад

      That is profile first and foremost front to to rear and very common. Second would be adding 2-3psi cold to the rear and seeing if that helped. If not, then a 180/60 would make sense or a 190/55.

    Hi sir, I'm experiencing the opposite on my CBR500R. I was checking my tires yesterday and I have about 1/4" of chicken strip on the rear, but the front is almost to the very edge of the tire. I felt like this should be the opposite and after checking around that seems to be the case. Do you have any idea what would be causing this? I definitely don't want the front end slipping out from under me.

    • @catalystreactionsbw
      @catalystreactionsbw  4 года назад +1

      Is you front tire pressure lower than the rear by 3-5psi? If so you will be flexing the front tire and reaching the edge because of the low pressure. Match the front pressure to the rear and see if there's a new area of wear that is less than before.

    I ride with an old fella who has several motorcycles and ALL of em he uses almost the entire front tire from his old brit twin to his boxer to his Sportster powered Buell. No knee dragging no hanging off the guy just rides fast in his mid 70s Now Im no sloutch but I cant pace with him and always have quite the wide chicken strip on my front tire even if I use most all of the rear. I was hoping there was some simple answer lol btw Damn you looked so much younger 12 years ago these latter years are just so unfairly unkind lol

    What is a chicken strip?
    Just picked up a new bike couple weeks ago, not familiar with the lingo.

    • @catalystreactionsbw
      @catalystreactionsbw  3 месяца назад

      It is the area of tyre that is not in contact with the ground. This directly relates to the lean angle used. The less you lean, the bigger the area of unused tire, therefore you are a 'chicken" as you will not lean the bike over. As a frame of reference, I always have chicken strips on my bikes, even my race bikes as I do not need all of the tire.

      @VLK-73 3 месяца назад

      @@catalystreactionsbw lol thank you for the explanation.
      If that is the case, my chicken strips are pretty much taking up the whole tire, as I'm not too keen of leaning the bike very much for the fear of the bike sliding from underneeth me and ending up either in a ditch or the oncoming traffic, depending on which way the road curves.
      Do you have any good tips for finding out the limits of the lean angle traction, without actually dropping the bike first?
      I spent all my $ on this bike and don't want to find out the hard way...:)

    I don't care about chicken strips, because I'm not trying to risk leaning my bike to that much of angle on public roads; which usually have sand or dirt on the roads and could cause me to slide my bike. Besides, chicken strips are delicious.
