I can't remember how long they lasted, but I don't recall any memories of thinking they wore out too fast.
I did buy them for street-biased use, and they were excellent for that.

I do remember the GP1s having thin construction compared to an off-road knobby or even the stock Bridgestone tires from a WR-250R, so they're probably not the best to prevent pinch flats in rocky terrain.

For dual-purpose off-road use, I typically compromise at 18 psi.

I have used 270's on a KLR and a KTM 640 with good results and life. My husky ate rear tires and an MT21 would last 1500 miles. so I never tried a 270 on that bike.

On a light bike like the WR I see no reason not to run a 270 if you do street and mild dirt. They are soft and were squirmy on my heavy KLR but somehow wore really well. I think low HP helps a lot, and on a significantly lighter WR I think they would wear very well.

Yeah.. those WR250Rs can't be any kinda real adventure bike right!... haha!! WRONG! BigDog and Dingweeds continue riding our WR250Rs on more epic adventures.. they head to Baja today. They've ridden from the Artic Ocean to Baja on WR250Rs, that pretty much says it all to the 250 nah-sayers

ANYWHERE!

Like our disclaimer says......

Has anyone installed this kit without removing the engine? Not sure if it's possible.

Nice.

>"ps. Isn't a IRC GP1 a copy of the Kenda 270?"

Yes... just suggesting different tires rather than pulling your bike apart or adjusting suspension.

If you've mounted a 606 on the back of your bike, check it also. I mounted one on my DR350... it created an intermittent vibration like you're feeling. I pulled the back end off the ground, put the bike in gear... the tire wasn't round, even though it was mounted properly on the rim.

I hope Mark is documenting it
Is he for sure on his WRR or his new Terra 650??

The 606 was mounted a month ago before the Kenda. The problem only started after mounting just the Kenda a couple weeks ago. I'm pretty sure it is just a defective tire and I'm going out in a few minutes to check for it being out of round. It may settle down after some more break'in.

ps. I just got finished checking it and it appears to run between 1/16th and 3/32nds out of round. As I posed before not enough to get rid of the tire. just break it in more, and use it for light trail/offroad.

UtahFox,

Thanks heaps for the link to HighFive's project. I hadn't seen it before and it's excellent~! Just what I was looking for.

I got about 5000 miles from a 270 on the rear of my WR250R. Traction always seem fine in dry dirt and rocks of southern California. Still had at least 3 mm of tread in center when i swapped it out for an MT 43. The trials tire is wearing faster but gives me much more confidence with traction on the streets and freeways of LA and amazing reaction off road with exception of deep sand. K270 just didn't inspire confidence on freeway interchanges at speed for this noob. Felt squirmy and I always felt like I had to slow down to hold the lane.

NP J dub dub. Are you planning on doing it, or just kinda seeing how hard it'll be? If you do it, please let us know here how it goes for you :)

Just trying combos to see if I can find an inexpensive substitute for the OEM trailwings. I am running the 270 on the front and a 606 rear. Had it out today and it felt a little loose on pea gravel but otherwise ok on hard pack dirt, even wet surface considering it is a defective tire. Not a supermoto tire but it is fresh so it is holding on tarmac OK>

ps. Next up are Shinko 700 series, then following that a Duro 903/4 combo on Markk53's recommendation

My WR came to me with Kenda 270. I haven't had it on the trails yet, but it sucks in snow That's all I tell you until the snow melts. Anyway, as soon as it is worn out, I'll be putting Trakmasters on it. I had them on my KLR250 and loved them in mud, sand, gravel, and okay on the street till about 70mph.
