125-200cc supermoto tyre question for wr125

hello all
right i managed to get some supermoto wheels for my wr125 but am wanting to know what the widest tyre for the rear i can get for it is?
i dont want any rubbing so am presuming a 140 would be the widest or does anyone know if i can get a 150 on there without rubbing please

anyone???

Hey av it
Cant help you with the 125 cause I don’t know anything about it but another source for answers might be supermotojunkie ?

thanks for the supermoto junkie link up but i am a member on there allready
i fitted the wheels and a 150 wide just clears my o ring chain so thanks again

i have a SM125, comes stock with a 150 rear tire, looks like this:




theres not much clearance to speak of, i dont think i wouldbe gone any wider than that..

edit: sorry didnt see that you already put on the tire

You guys need to put some pics of that sm bike
I bet that thing is a riot !

i will get some sorted this weekend cheers

Does the 125 engine last long being at constant rev all day?

What wheels did you get that fit it?

hey,

just noticed this thread. i own a SM125. It shares the same specs as WRE125 2008 model. I dont know if this model is available there. im running on 110 front tyre and rear 150. Currently on Bridgestone Battlax BT90. The stock Dunlop A10 wear off and overheat too fast. These are some specs bout my bike cheers.

Mr X, do you ride your bike on the street or track only? How is it on the street? Do you feel like it has enough power? I am looking to tag/supermoto my cr125 for my 5 mile commute through the twisties every day and want to know if it would be worth it or if I should sell for something bigger? Can it cruise at a decent clip without being completely wrung out?

I have a WR 300, but i don´t know if the width of the swingarm is the same, but i use 165/55x17 rearwheel. Cut slick. (Early spring so raintyre at front)

I dont how much difference is sm125 from cr125 but for sure the sm125 is built for road and track use.the fuel consumption is good; between 20-23km/litre.i have 42000km mileage since 17 jan 2009. Problems so far; c.d.i crashed once, valve motor spoilt once and some wiring issues. Other than that, following the servicibg schedule, the bike is fine. I hit 157km/hr before with 28mm carb, 47t rear sprocket and arrow full system exhaust.
