I have a MOT coming up in 2 weeks and i know i need a front tyre. The front tyre fitted is a 80/90/21 but i seem to be getting better results looking for a 90/90/21. Will the 90/90/21 fit? Does anybody know of a cheap supplier,i dont do alot of milage so a budget one will be ok,i want to stay with the knobbly look but not the motocross type,if you know what i mean. ,ay be even someone on here has one??
