Trials Tire on the YZ report+video

15 posts in this topic

Finally was able to get out for my first ride on the IRC tubeless trials tire that I mounted up on my 426 using an 18" WR wheel that I got from Moto2000 and it was incredible. :lol::confused:

In short...this tire rips. It is incredible, it's like having an extra inch of suspension and it absorbs and grabs onto everything it rolls over. Tight single track with mud, rocks, and tree roots was a breeze. This thing did not slip unless I wanted it to. Wet tree roots while cornering? No problem. Riding up a dry streambed of softball-sized rocks with a 1/2 inch of snow on top? No problem. :crazy:

Here's a quick video of us going up a powerline road that was loose gravel covered with loose semi-compact snow and ice on it. The two bikes with knobbies had to be manhandled up the hill and pushed the last 50 yards. With the trials tire I motored right up...the videographer did not appreciate the fact that I didn't have to get off and push like he did as you can tell by his comment :confused:http://video.google.com/videoplay?docid=7848196241357492629 By the way, both my YZ426 and my buddies YZ450 run Rekluse clutches.

That is so cool..

But there must have been some ice on that trail.

I think riding the sand like I do has got to be a lot easier than that.. :lol:

***Update***

I just ran my first offroad race with the trials tire. It was mostly tight single track through the woods with lots of tree roots, rocks, and mud and lots of steep twisty ascents and descents. The tire hooked up awesomely and allowed me to pass several people on rocky and tree-rooted hillclimbs without much more thought than twisting the throttle. Had no problems at all with mud. I took first in my class and will run this tire at any series race that is in the woods!

Do you think the trials tire would perform well on hardpack/shale/rocks in Coal regions??

I would recommend it for anything except gumbo-mud, sand dunes, MX racing, and high speed desert type riding. But for hardpack, shale, and rocks as you mention I think you would be hard pressed to find a better tire. There was a section of our course yesterday that ran right up an intermittent streambed that was all broken shale type rocks similar to 4" riprap and I was able to pass three guys that were running knobbies because they were skipping and kicking all over...every direction but straight. I just kept the power on and the front end light and the tire simply absorbed everything and tracked straight as an arrow.

I just spent a weekend riding on one for the first time. It was ice covered rocky terrain with an inch of snow on top. This tire worked exactly as you have described, I was truly amazed! I had my other wheel all studded up and never used it. The other 6 guys I was riding with lost all thier studs and were having all kinds of problems.

Sounds like a winner for what I'll be using it for...but, I do hit the track occasionally. What is the problem with using it on a MX track??, does it just not grab? or some other problem?

There isn't much in the way of cornering knobs for extreme lean angle...even though you are in a rut or berm anyways it still kind of freaks me out. In full-on horsepower situations like starts or blasting out of a corner it won't work as well as a knobby...and you will feel the sidewall flexing and mushing around...the trials sidewall is designed to flex and absorb...exactly the opposite of a motocross tire.

Now if you are talking about going out to the track for practice days...that's a different story and it could be very serviceable. I wouldn't try launching any triples though!

I keep a knobby mounted up on my 19" wheel for the times that I'm going to the track or out to the 4th & 5th gear wide open stuff.
