    My highest speed crash ever was from hitting wet grass at about 70 mph running trials tires. Just the slightest touch of the front brake to set up for a turn and I was instantly on my face sliding. I may as well have been riding on ice.

    I am almost convinced to try a rear again on my 200. But I don't think I will ever have the guts to run a trials tire on the front again. Just the idea of going down a steep hill or hitting slick mud on a front trials tire makes me cringe.

    Front trials is not for carving on a motocross track for certain. Actually anyplace where huge carving demands are put on the front tire side knobs. But for my more laid back riding, they are superior in some places and I make adjustments in other places. And they last for a long long time.

    Common practice in my neck of the woods is to run a knobbly front with an MT43 rear. I have ridden the length of France on motorways with an MT43 without issues. Lowest I have run one was 2psi - I had a slow puncture. A bit squirmy when I opened the throttle but no pinch flats and incredible grip.

    I have a partial worn Pirelli XCMH on the front and will switch it to a Golden Tyre 213 or 216 later in the year. I am pretty certain I will stick with the knobby on the front.

    Just mounted this a couple of days ago and found a paint pen;) It will wear off shortly...

    One more comment for the person wondering about trials on the front.

    I failed to mention what is probably the main reason I run trials on the front. My perception is the front deflects off rocks less with the trials tire. Everything on a M/C is a compromise, gain here, loose there, but for my type (trail) riding that often consist of narrow shelf type single track on the side of a mountain, I trade the advantages of a knobby for what I perceive as the advantages of the trials tire.

    I have not read where anyone else mentions this advantage of a trials on the front but it is my perception.

    I did some more riding this Friday at Johnson Valley & Cougar Buttes. This time I didnt just ride solid rock we rode sand & DG. We did alot of loose climbs and the tire works better, when it spinning it dosent hope around like a knobby. This was 2nd ride day with thie trials tires and I still think there the best tire to have.

    I run front and rear and can say if you're MX'ing your bike the front might not be the best for you, BUT having said that I ran the PB300 last fall and had 0 issues with them. Both worked really well in all conditions we experienced but I can believe that the rear might not be the best choice if you ride in sticky/heavy mud. YMMV

    I didn't get into any real mud on my one try with the MT43 but on the radial trials that I run on the rear my experience is they seem to clean as well or better than a knob. The explanation I've heard is that because of the flex, the knobs on the trials tires are constantly opening and closing which tends to help release the mud.

    But on the higher pressure front trials tire which are all bias and don't flex much, yeah, cleaning in mud can be a problem.

    On pavement, how much pressure do you run in the rear?

    I'm too lazy to change pressure so I just keep it where it is 8-10lb and they wear forever no problems but hey I'm not knee dragging either .:lol3

    Really nasty stuff I will gather my forces and drop to 6lb and for connecting pavement I have no problems leaving it at that.

    MT21 front, hating pavement?
    It's about the most pavement friendly of the knobbly fronts.

    I've got an MT43 front on the way. I'll either hate it or it'll match my riding style well.
    Can't wait to find out.

    What do you think of the MT43 front? I just installed MT43's on the front and rear but won't be able to ride for a few days (Colorado Rockies). This will be my first time riding on trials tires.

    I like it on the front. Did 3hrs today and the rear let me down more :D
    Very good under brakes on anything non-muddy.

    I don't go fast so there's no leaning it over and nailing it through corners.

    I Was on the fence for some time about the MT43 on the rear. However I have now mounted the MT21 on both ends. Seem to be working well if you keep the pressure 15lbs of so.
    I will someday get a MT43 for the rear to see what all the HooRah'n about !

    I'm trying to follow this discussion and one like it on another thread. Please check my distinctions here, because this is the only way it makes sense to me:
    The MT-43 is a HYBRID tire: very stiff sidewall with a trials tread. Hence it works well on the road, and on rock, and on sticky soils, but less well on sand (?) and in deep mud. Low pressure off-road for traction; higher pressure on-road to mitigate heat build-up and provide excellent longevity. So, you need a pump.

    The MT-43 is more likely to be loved by trials riders and (usually) hated by moto-cross and competition enduro riders, especially on the front. The racers put too much stress on the front and it washes out. Trials riders are going at a much slower pace and this allows the front to exert its grip rather than be pushed laterally.

    Hence, dual sport riders are expected to like the MT-43 front if they are on single track and are riding at a moderate pace. On a WRR or DR, for example, they will shine at lower speeds. And almost anything will work on two-track and dirt / gravel roads.

    At the same time, current and former race riders who are riding the new race-based "dual sports" (e.g. KTM 350/500's, Bergs, Huskies) are less likely to be fond of the MT-43 front as they are used to riding faster and want to take advantage of their cutting-edge hardware. They tend to ride past the front tire's limits.

    And there are some surfaces that are just not MT-43 friendly, but the MT-43 is a lot more friendly to the trails than a knobbie.
    So, it is not really all about terrain, but about riding style, too.

    Does this sound right?

    I ride a WR250R. I have the 43 on the back. Riding yesterday in muddy hilly terrain. Putting a 43 on the front in those conditions would have been a truly religious experience...front brake is better than no brake. I would never go with both where I ride.

    Yep. if you're going to lean the bike over and give it a handful then trials tyres aren't for you.

    Met a guy on a KTM300 on Sunday. MT43 rear and knobblie front. The MT43 had been on since December and was half worn. He runs 4psi and doesn't race, but loves the trials rears as they get him to where he wants to go with less fuss than with knobblies and they last a lot longer.

    Trials fronts are only really an advantage going slowly down non-slippery stuff under brakes. It's more sure footed than a full knob.

    I go slowly down stuff so it suits me :evil

    bumping old thread. sorry.

    I am interested in trying this mt43 on front and rear for my te630, especially since I probably fit the 'riding style' here in described (I am slow and still pretty green so I do not rip around corners and still go down hills dog slow) Anyone have experience with these on midweight bikes like a te630/te610? Wondering if this may be just what the doctor ordered
