  • Have to disagree with you there sideup. The introduction by FIM of the dead-man engine stop switch, is in my opinion the most important inclusion for WTC riders and should be applauded. No matter ho

  • How does a dead man operate the switch in the first place in fact why would the FIM even let a dead man start the event.

  • My dad would do Parades on his TLR200 Reflex. (Nose wheelies or Endos, a teeter totter. wheelies, ride over a car etc....) and he fashioned a kill switch with a set of points and non-conductive some

Guess we will all be riding belt driven or battery bikes next

Bloody elf "n" safety :)

Fair point Glen. I hadn't thought about that way. I'd assumed the sprocket guard was there to protect the sprocket from rocks not fingers from sprockets. :dunce:

I'd say it was designed to protect the sprocket from rocks.

it may also provide some limited protection to the sprocket but if that was its main purpose it wouldnt be made from tupperware. It does stop fingers going in if its correctly fitted and not damaged.

Dabster: what about the teeth on the sprocket? They can sever digits just as well as the holes but nobody has attempted a work-around for them.

They can but when minders grab bikes its the guillotine effect they are trying to stop I think

I think "dead mans switches" are a good idea although I don't have one on my bike (yet)

Regarding rear sprocket guards, my 76 OSSA MAR did not have one and I still have the scars to prove it on the fleshy part under my forearm from when I dropped the bike, slipped and fell on it. It was extremely painful and kept me off the bike for 2 weeks.
