Keith, I can't see any damage anywhere else on the bike; it's actually in very good condition with few scratches. Forks look straight enough though I guess you'd need to remove them to be sure. I came across an interesting video on You Tube that dealt with misaligned forks. In many cases it's the result of a bump - perhaps hitting a pothole - that causes the forks to twist in the yoke. Apparently it can be rectified by loosening all the bolts on the front forks bar the ones in the top yoke. Then it's a case of pumping the bars and twisting the forks until you get it all straightened up again, at which point you tighten the bolts up again. That's the theory, anyway. If anyone's interested, here's the link.
Either way, it's out of my hands for the time being. The bike went back to the shop on Saturday and I don't expect to see it again until the new year.
For now, it's Christmas Eve, and time for a mince pie.
Merry Christmas, one and all
