In May, when returning from the Dragon, I hit a really savage pothole on a Georgia backroad, when shaping to pass a car. The impact was so bad, I'm sure my shoulder blades met in the middle of my back and it was pretty bloody painful, quite apart from being knocked breathless.
At first the bike seemed to be OK but subsequently, there was a high-speed vibration at 80+ and sure enough, when I looked at the wheel when spinning, it was very slightly out of true but not discernably out of round. Closer inspection also revealed a loose/broken spoke - the little adjuster at the rim end must have sheared as it was spinning freely.
Nevertheless, the bike ran well enough for another 1000 miles to home where my dealer RPM sent it off to Buchanans. They replaced the broken spoke, trued and relaced the wheel and sent it back. The price was a very reasonable $145 including the shipping and also it included RPM removing/remounting/rebalancing the tyre. I was very glad to get my wheel back as mine is a 95 and so it has Akront alloy rims. It would appear that Triumph are only carrying the chrome items from later models, plus they're an arm and a leg.
In fact, that damage may have been cumulative as I had hit another bad pothole just north of DFW on 635 about two months before (really, Texas highways are appallingly maintained). So, I think the TB wheels must be a good deal stouter then the Bonnie items.
