Dualsport tire comparison for WR250R - Part 4

The last rear tire I tested was the Kenda K760 Trakmaster II in a 100/100-18. Although it seems a lot of WRR riders choose this size, I found it too small, too squirrelly, and too much of a sacrifice of top-end speed. So off it goes to Kijiji.

The next size up is the 110/100-18. It's on the left, the Pirelli MT43 I've been running lately is in the middle, and the 100/100-18 K760 is on the right. As you can see, for just one size up, the new K760 is quite a bit larger than the other one, and almost the same diameter as the MT43.


Here's the K760 compared to a Heidenau K60 Scout (4.00-18). Again, almost the same diameter which means I'm not losing too much top end for those inevitable paved highway sections. 


I'v only had the MT43 on my bike for about 1000 km of 50/50 riding. It's performed really well although I find the wear on the centre knobs somewhat alarming. Getting 2000km out of it will be lucky!


The K760 mounted up really easily once it sat in the sun and I gave it a squirt of Armorall. Love that new tire smell. That's an Ironman 47T sprocket. Still looks like new after 1000km of 50/50 riding.


Aaaand ready to ride.

The 110/100-18 fits the bike really well. Lots of clearance around the swingarm, no problems sliding it in. Weight is 11.9 lbs, compared to 13.7 lbs for the MT43 (4.00-18) it replaces.

It also handles great. Spent a few hours test riding at the local sand pit/MX playground, on various gravel and bush roads, in some big clay mud-holes, and on some stretches of paved highway. I didn't notice any power loss from the heavier rear tire compared to the smaller 100/100-18, as some WRR riders report. In fact, being slightly smaller in diameter than the MT43, and lighter by almost 2 lbs, my throttle felt a little more responsive although top-end was noticeably lower. Traction is excellent and together with the Pirelli Scorpion Pro in front, cornering and braking were positive and predictable. Other than tread howl at highway speed, my initial impressions is this is an excellent DOT tire combo for more aggressive offroad DS riding.

  1. I have a mt43 on the back and find i doesn't stop very quickly on pavement. I am running a Tubliss system with low pressure, maybe that's why? what has your experience been with the MT43 on pavement?

  2. It's actually been pretty sticky for me on pavement, although it wears fast! I run around 22psi as a compromise between pavement and dirt. Didn't try it with the Tubliss (too hard to balance for higher speeds). Cornering is good too. It's a nice comfy ride compared with a K760 full knobby, great over roots and rocky hard pack, and decent on gravel roads. Crappy in the mud though--packs up fast.

  3. I'm wondering if the 110/100 trakmaster is the same diameter as the stock tw302? Since the 100/100 looked so small. Can you confirm?

    1. It seems pretty close, but I don't have a TW to compare with. Plus the knobs are so high compared with the TW. There's no doubt the 100/100 is too small: just not enough air volume to run low pressure and provide any kind of protection for the rim. The 110/100 works great though. Will be ordering another one soon.

    2. Perfect! Thanks for the info, I'm just about to order a set to try. Riding in the mud a couple of weeks on with the stock TW was interesting to say the least. I'll go with the 110/100.

    3. I've heard the TrakMaster II front tire is not good. I'm running a Scorpion Pro FIM and really like it. If you can't find one of those, an MT21 is pretty good too. Both are DOT and give reasonable on-road life as well.

  4. Oh I see, thanks for the heads up about the front. I'll see about those tires you mentioned to see if I could order them from the same place!

  5. Looks like a slightly cheaper alternative to the Dunlop 606.
