Cos when you lob the bike off road the indicators get bust, when you get on with MX boots guess what, yep the indicators get bust. When your on the trail and the mud and stones are flying, yep the bloody things get bust.
Add to that they rust out and the indicators sieze into them too, so they get cut off.
Addmitedly my brackets got the cruelest cut thanks to a smarmy MOT man long after the indicators were consigned to the bin, "if the provision is there they should be fitted and work, thats failed".
Hour later i was back minus the provision He didn't like it but he had to pass it.
