    Not looking for brace or guard, the plastic shroud itself got damaged and I need to replace it.

    TNX for the recommendation on tires guys. I have one more check to do tomorrow to see if it is "out of round", if it is I will probably leave it on for now and just do some winter trail riding. I have a fairly new 606 on the rear. Possibly the high spot will get worn in a little while I do load testing in anticipation of my summer trip. I only payed $46.00 for the Kenda 270 so it isn't worth taking it off and returning it to Rocky Mountain MC. I already have a TKC 80 or Shinko 700 to replace it with in the spring before I leave for my trip to AK./Yukon and I have a set of Warp 9 wheels I'll use for that trip.
    ps. Isn't a IRC GP1 a copy of the Kenda 270?

    i would say its sold as one Part two sides with rivets.

    I put a Flatlands racing guard on mine,it touches the big IMS tank lightly so i had to put some rubber between the two

    I recently had Pirelli Scorpion Pro Enduro f/r on my new WRR. The Pirelli's are pretty much as aggressive as you can get and still be DOT approved. Instead of traditional balancing, I had approx 3 oz of beads installed along with "Lite-lock" rimlocks. I've only had her up to 70 MPH, but the new tires at 15 PSI feel pretty much as smooth as the OEM Trailwings.

    If anything, the Kenda K270 is a copy of the IRC GP1.
    A cheap copy.

    I was using IRC GP1s on my 1990 Yamaha DT-200R back in the day, and they were/are awesome tires for smooth running on the street with casual off-road use, and that's the reason I mounded the IRCs for a trip up to Mt. Washington from CT. back then.
    The wheels were balanced after the tires were mounted (with an old-fashioned static balancer), and the bike was as smooth as glass for the trip up and back.

    Myself, I'd recheck the balancing job with another wheel balancer.
    You may be surprised.

    Actually the Kenda is a "copy" of the old Yokohama, which was run as OEM on a bunch of 70s Honda dual sports. I was running the Yokohamas on my trials bike around 1983. I'm thinking Kenda may have bought the Yokohama tooling when they quit doing bike tires. Shinko got some of the tooling too.

    Personally I've had great success with the Duro HF903/904, but I don't know if they're available in the correct rear size.

    I have always wondered about the GP110 myself. But the Duros have done so well both on and off road, that with the price they are, I just won't change. Oh, I run them on a 650, was just nosing around in this thread.

    Yes,YZEtc you may be correct about the order. The Kenda 270's seem to run $5-7 cheaper than the IRC GP1's and I was just looking for an inexpensive trail and hard surface general tire. What type of mileage did you get out of your GP1s, and what pressure did you run it at off- Hard surface?

    Hello Mark,

    Thanks for the clarification, I believe I have seen your avatar on some RR's and 650 forums :lol3
    ps the Motorcycle-superstore still sells them: http://www.motorcycle-superstore.co...Duro-HF-903-Median-Dual-Sport-Front-Tire.aspx

    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. :puke1 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 :evil

    ANYWHERE! :thumb

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

    >"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.

    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.
