Hi guys,

I want to change the rear tyre of my YBR 125, it's way too thin and I want to get a wider one.

I will change the rear tyre and put in in the front, buying a new tyre for the back.

What is the maximum size you think I can get? I tried a 100/90 and it fits, do you think a 110/90 will fit or it's too large for the rim?

What do you hope to achieve by changing the tyres? Perhaps you could get away with an extra 10mm but I doubt much more would be advisable without changing the wheel.

I have seen Andrewelvisfan grinding the undercarriage on his SR with stock average rubber so why bother.

I have a YBR custom, as far as I know the frame and swing arm are the same. I have a 3.50 - 16 58p on the back of my bike, (Thats a 100/90 tyre in metric terms). You'd probably be able to get away with a slightly wider tyre, like the none I have, but you'd have to look at the spacing on either side of the tyre and just guess. 

DON'T put a used rear tyre on the front of your bike !!!   It's lethal mate .  I did so in an emergency once and it was terrifying .  Think handling like a Lego motorbike and you'll get the idea .  Best to stick with the recommended .

For handling best stick to the standard size when you go wider it might look better but will handle worse as the wall of the tyre will have more movement
