Unnerving Wobble

Well I'm having the head bearings looked at on Tuesday but I'm hoping it's the tires as that's my next purchase. My front tire right now is from 2006 and my rear from 2004.

You are running tyres that are at least 11 years old? Jeez to me that is dangerous and will severely affect the handling of the bike,  rubber perishes, goes hard and deteriorates over time so for me rather than mess with head bearings I'd change both tyres immediately to something like Michelin PR4's and then see if you have an issue still or not.

At a guess if your tyres are from 2004/6 then you may still have the original Bridgestone 020's fitted which were a shite tyre at best.

My mate ran "old" tyres like you - had a blow out on the motorway ay 70mph due to the rubber having deteriorated to the point there was no give in the tyre. I seriously suggest you change those as your first priority as that is most likely where your issue is

Well, turns out that after all my faffing, the problem was an ever so slightly misaligned front end. All sorted (got some Battleax T30 Evo's too) and she's handling like a dream.

Thanks for the help guys
