The spoke pinging session was triggered by two recent reports of big BMWs' rear wheels collapsing at motorway speeds, and a report of a Guzzi V85TT meeting a similar fate out in the wilds of northern Canada, miles from anywhere - happily the guy limped away.
None of which form part of the two wheel experience any of us want.
About 20 years ago, I remember several people I knew who had early Hinckley Bonnevilles having the odd spoke on the rear wheel break; fortunately without catastrophic consequences, but still not great. IIRC, Triumph issued instructions to dealers to check that the (stainless steel) spokes were tightened to the correct torque as part of routine servicing.Must admit to never in my biking experience ever heard of spoked wheels failing, you would assume that this would be down to human error ( not built properly ?, loose spokes etc. ) or would it be down to the forces being put through the wheels with todays higher torque/horse power ?..dunno
70's super bikes were knocking out 79-80 bhp on spoked wheels and factory GP bikes even more. The Thruxton Triumph 1200 knocks out over 100bhp.
I might save the calculation of how many 18V Li batteries would be needed to replace a typial EV car battery for when I really don't want to do the task in front of me!Yes, I have a collection and just the two batteries......
I must admit the Comstar wheels on my Honda 750 F2 did make me wonder about the alloy riveted design at the time but never had any problems then. But if I was buying one of these classics now you might think about corrosion after 40 odd years.About 20 years ago, I remember several people I knew who had early Hinckley Bonnevilles having the odd spoke on the rear wheel break; fortunately without catastrophic consequences, but still not great.

On the other hand, in my brief period as a courier riding BMW R850Rs, we were told to be careful going on and off kerbs as the cast wheels were prone to cracking if abused. Also, a few years ago, a friend had the cast rear wheel of his Suzuki 1200 Bandit fail at speed for no apparent reason. Both his legs were very badly injured, though he has pretty much recovered now.
I do worry sometimes about the cast wheels on my '97 CB500, especially given the parlous state of the roads now.
I seem to recall (but don't know if true) that the Comstar wheels were glued together and the 'rivets' were only cosmetic because riders of the day would not trust only adhesives to keep everything together.I must admit the Comstar wheels on my Honda 750 F2 did make me wonder about the alloy riveted design at the time but never had any problems then.
In the late 1990s/early 00s, the reconstituted MZ (MuZ) made some bikes with British designed, glued frames. Never heard any reports of problems with them, but on the other hand, you rarely, if ever see one on the road nowadays...wikipedia suggests rivets, and I always assumed that to be the case.

these boys don't mention adhesive Home
I imagine one of our pilots will be along soon with tales of glued together aircraft (thinking full size, Heather )
POSTSCRIPT
I hate it when I write a post and forget to hit “send”. My excuse was that it was breakfast time..,
My broker says that it's the dealer's responsibility. It's going to be a large claim. I am guessing that there must be in excess of 100 cars affected, including new and unregistered Range Rovers, Land Rovers and Jaguars. So probably £5-10M for the vehicles plus the damage to the buildings and contents. I am expecting to be told on Thursday when I can expect to be told what's happened to mine.I’d guess that’s a write-off, but I wonder whose insurance pays out?
Bottom line, we all do…
