New front tyre fitted and now a singing bearing noise present

[Bad bad boy]

Have you checked the tyre pressure is correct.

  Thanks Bandit and everyone else for your thoughts, ive had a totally strip down this afternoon as I suspected error when the wheel was fitted, bearings out and new ones on order, the bearing next too the outer spacer feels very rough, therefore I think the fitter has over tightened the axle spindle at some point causing the defect, it could well be the case that this bearing was on it's way out, and the over tightening has finished it off, you can only really hear it when it's under load, the tightness of the axle bolt was defo well over 67NM, I will let you know if the new bearings have done the trick, they are in the post now, if it is, beware of tyre fitting firms who are not just 100% motorcycle, live and learn I suppose.
