First of all what miles has your bike got?

How many miles has your front wheel been on for?


First off when your front tyre wears it doesnt wear evenly so will wobble a bit but normally you will not notice this untill its quiet big like yours is now. If a wheel weight comes off it will give you the same feeling but very instant change. Or if your head race bearings are worn so much this will also give the same effect but this takes a good lot of miles or failed wheelie attempts to wear them out.
