You've 'gotta be lucky.

[Mike63]

.....I recently had a terrible accident that put me in hospital for 3 weeks and has kept me off my bike for 3 months.
One of the bar ends had come off and I couldn't make it stay on, as a result when I came off my bike the bare metal of my handlebar stabbed me in the groin.

....the only lucky thing was it didn't get me 2" lower.

...or at least I thought that was the only lucky thing till I saw this add.

I think a police officer could take a bike off the road if fitted with those, obviously a danger to everyone and not just the rider!

I have seen lots of motorbikes in Denmark and Germany with nonesense like that on them. The police over here are now cracking down hard on them.
