    What size 244 are you running on the rear? 4.60 or 5.10?

    Since I'm out of town, I don't have the ability to get both wheels off the ground. Should I find a Yamaha dealer around here and get their help before I head off home?

    In the picture, that was an older XT600, but I have a set of 244's waiting to go on my WRR. I went with the 4.60 x 18 rear for my WRR. I saw no reason to go with the 5.10 rear on a 250. I'm actually running the 4.10 x 18 rear on my wife's XT225. We'll see how the 4.60 does on the WRR.

    I wouldn't. Just gas it up and go. Do the basic stuff first--there should be enough tools in the oem tool kit to check the air filter, check the oil level, pull the front sprocket cover and check that the chain slider is still protecting the swingarm, check the chain slack. Check the tire pressures. Make sure all the lights are working. Once you're satisfied, hit the road. Assume they're out to get you, and ride smart!

    Mess with it when you get home. Doing all pavement your Seat Concepts seat should give you enough comfort for the ride:wink:

    Thank you.

    I am running a 4.60 on the rear, also. I was wondering if going to a 5.10 would gain me any traction with the larger footprint or if I would just gain the weight.

    Huh, I guess math really can be interesting. Makes me wish I had stayed awake more in class...

    I could see the 5.10 on the 17" wheel because I think its actually a wider rim than the 18" rim? On the 18" rim, I think it will just be pinched not sure it will really gain you anything except extra weight and a higher cost.

    Got my new Seat Concept seat, and have installed some USB power too. The tank bag is new, the duffel is packed and mounted with one and a half gallons of gas, as I plan on trying to get home with no slab. Not sure why I'm leaving though, was 82 here today and 35 where I'm going. :cry

    Does anyone know if a Pirelli XCMH 140/80M-18 will fit the WRR?

    Thanks

    that sounds really big. it may fit, but the little WR is way happier with a smaller tire.

    In my last move, my OEM seat seems to have vanished. This is not good since I want Seat Concepts to send me their foam/cover and need something to put it on. Have one to sell? One to get rid of? Thanks!

    The WR-R is spec'd for a 120/80-18, which is about 4.7" in width. The 140/80-18 is about 5.5" wide and will be taller as well. The extra circumference would have the effect of making whatever gearing you're running taller (more top end, less grunt). Also, with a tire that large you might have clearance issues with the swing arm or need to get a longer chain to allow the wheel to be pushed farther back. I'd stick with a 120 size or there about.

    The Pirelli XCMH only comes in the sizes below. I guess that most are running 120/100 - 18. By my calculations this tire is about an inch taller than stock (4.8" vs 3.8").

    I'll just use a brand with the stock size.

    Thanks
