Handlebar wobble

[Bretty]

My bike has always had a wobble if you take your hands off the bars between 30 and 60mph. On 3 different front tyres. I seem to remember reading (on here?) that it was common on the fazer.

With my hands on the bars there is never any wobble at all.

Have you got weights on the ends of your bars? My bike came with them on.

I would always check the tyre and wheel are balance before id consider changing a tyre. Balancing is pretty important on a bike.
