Hi all,
Have recently taken delivery of an old (but seemingly healthy) 1100. Amongst a few easily sorted issues, there was a definite steering wobble / bar oscillation between 30-55 mph, despite re-balancing of front. Tyres WERE Storm Ultra STs, and reading this (superb) site has shown that many people think there is an issue with these tyres.
It seems that 021/23 Battlaxes are a good choice for the Pan, so I decided to experiment using a pair of second hand wheels, complete with Bridgestones. The rear went straight on (with new cush rubbers to get rid of the drive-off 'clunk') and the wobble reduced in intensity a bit.
Changing the front was a complete revelation! Literally no wobble of any sort, even hands off. Banging the bar hard would induce an oscillation that sorted itself out almost straight away.
I cannot believe the improvement and the same issue was the main reason I am selling my previous bike, an excellent CBF1000. Same tyres!
I am annoyed with Avon, because there is clearly an issue here. I have spent money on balancing, more balancing and even head bearings on my CBF.
The rear on my ST had squared off, effectively, into 3 flats (despite having lots of tread left) and I presumed this was the problem. The front looked fine, with a perfect radius.
Lesson learned!
