    This Kenda mounted up tight and popped loudly twice when I aired it up, it's on there as good as any other tire I've had, plus, it absolutley does not leak any air over the many months that it's been on.

    The Kenda worked fine off road, I wasn't trying to go very fast off-road with that bike, it did OK. And if you call a TKC a dual sport tire, yeah, this is a rear tire as well, a 130, I had to grind the edge knobs down to fit inside the fender. It didn't like anything over 80mph either.

    I run shinkos all the time on 4 different tigers and have yet to have one come apart whether bias ply or radial ..............lasts a long time on the tigers , not uncommon for a front 705 to go 10 k easily.

    I was mistaken though on the size ...in the photo I posted thats a 130/17 mounted reversed on the front .on the rear is a dunlop 616 because shinko doesn't make a 180/17

    I ran a 120/90 Shinko 705 and also an Anakee II in the same size on the front of a Versys. Worked fine. But the best I found for gravel road riding was a 4.60 Shinko 244 up front aired down to about 22 lbs. Ran them all tubeless. :eek2

    I run Avon Distanzia's on my TDM. The front is a rear tyre run backwards. Ive done this for over 90,000 ks and on all manner of roads and trails loaded or light without any trouble and in all manner of weather conditions from hot sand to iced up roads.
    Hills flats straights bendy bits the lot.

    Iv had more than enough opportunity to come unstuck and that's just not happened.

    It wont turn your bike into the devil or throw you into every oncoming car nor will it try to bite every passer buy.

    And I get huge mileage out of the fronts. 35 to 38,000 Ks. That shit over any road tyre.

    Don't do that because the treads will not work when wet.

    Sure it will. The traction for the front is for braking, for the rear is accellerating. They are opposite functions.
    A tire will throw water either way as long as there are sipes.

    Still, a lot of people doing this like to run in the direction indicated. I think it has something to do with their comfort zone. They're already breaking the laws of nature just by running a rear in front, then god help them if they ran it backwards. :lol3

    So 90% of the time I buy my tires from Motorcycle Superstore but last night I decided to look at Dennis Kirk.They list a 120/90-17 Kenda K761 FRONT or REAR tire !!.It has a different part # then the rear tire !!.Interesting me thinks !!!.

    Don't you hate it when you have been doing something for along time and someone tells you it won't work and the next day it doesn't!!!.Kinda like the CT on the back of my Vstrom !!.

    So why most tires have almost the same treads design for the front and the rear?

    By far the main function of the tire tread is to evacuate water.

    Front what I undetstand the front and rear tires are bilt different under the the tread,they may look alike ( tread wise ) but are built to handle 2 different functions...

    Except for tread design, I don't think a tire cares which way it runs. Bias tires are reinforced by 45 degree cords rim to rim that overlap one another. That is what plies are all about. Radial cords cross at a 90 degree angle. It may have been pertinent at one time, but modern tires have steel cords now and most have a belt that overlap the cords and runs around the circumference.

    I understand the weight transfer issue, but rear tires seem to be able to be used for braking as well as acceleration. If you have a directional tire, it should run in the direction of the arrow, as that is what provides the best grip, based on the tread design.

    less weave and wobble with it reversed vs mounted the rotation direction arrow......I tried both ways , reversed was best . YMMV :D
    on the 705 on a tiger anyway :evil

    I routinely flip my front TKC when they start cupping and have never noticed any difference.:evil TKC's are directional, but I can't see any difference in the tread.

    The advice to run the tires in the direction of the arrow, is the tire manufacturers, not mine. If you do some searching of tire threads, that appears to be the only objection

    Basically there are two types of motorcycle tires treads. Treads perpendicular to the direction of travel and the treads in diagonal direction.
    If the tread is perpendicular to the direction of travel in that direction are installed will have no effect on the behavior of the wheel. The designs are made diagonal to remove water from the contact area towards the edges as the wheel rotates, so these treads make an arrowhead in the direction of rotation, both the front and rear wheel. If installed inverted the arrowhead tread could accumulate water towards the contact area, facilitating the aquaplaning.

    The discussion was about dualsport tires for running gravel on the Alcan. If you're gonna eavesdrop, pay attention. :rofl

    Seriously, the rear treadblocks are designed for propelling the bike forward on dirt surfaces. Braking is secondary. Since the front wheel can't propel the bike it's sole grip function is for braking and cornering. The tire manufacturer will put a direction arrow on the tire to best take advantage of their tread design. A rear on a front should run in reverse so the best grip is for braking. As far as road tires having the same tread desing, true, but not true on adventure and dualsport tires. Similar, but not the same. Even knob height gets considered - too much makes the tire unstable on the road.

    But everyone is confused by this tread direction thing because the manufactueres flip flop on us too. Compare the front tread on a Pirelli Scorpion Trail and a Karoo 2. One has the knobs running in a vee facing forward to cup on braking, the other facing backward like a rear knob pattern. Which is right? Both are directional.

    More important is tire shape if you're gonna lean the bike. Many rear tires have a less rounded profile on a designated rear design and you can over ride them on the front. Just keep an eye on your chicken strips when you start bending the bike over in turns.

    On road tire design is a whole 'nother animal. You get into profile shapes, compounds, heights and shoulder designs, lots'a road racing stuff there. Lots of sipes, no sipes, and on and on. And that's where you got your opinion that 'tread is for shedding water' but that's just a small part of the equation.
