PB1 Posted April 22, 2012 Share Posted April 22, 2012 On my RS200, and I assume most front drum-braked '70s/'80s bikes that used the same front brake lever, the righhand mirror has a lefthand thread and the lefthand mirror has a conventional righthand thread. What's going on here then? Anyone know the reason for this? It can't be so that wind pressure at speed does not unscrew them, as they both have the wrong handed thread for that, so what can be the design reason for this? It buggers me up a bit as I have a very nice pair of chromed mirrors to put on the bike, but both have righthand threads. I think it's going to be a case of drilling, sleeving and recutting a righthand thread in the righthand brake lever. Link to comment Share on other sites More sharing options...
nayruf Posted April 22, 2012 Share Posted April 22, 2012 Hi PB1 Before I drilled and tapped a new thread in the original mount, Try a bicycle shop and buy a handle bar mirror clamp it probably won't cost much, My DT mirror is mounted using one of these i had lying around and it don't look too bad.

Moderator Airhead Posted April 22, 2012 Moderator Share Posted April 22, 2012 it helps them to not shear off in a fall Link to comment Share on other sites More sharing options...
Moderator drewpy Posted April 22, 2012 Moderator Share Posted April 22, 2012 you can get adapters to fit them. M&P (Busters) do them I think. Link to comment Share on other sites More sharing options...
YPVS TONE Posted April 22, 2012 Share Posted April 22, 2012 As Airhead has said if the mirror hits something when you're moving forward they are supposed to unscrew rather then shear off and ruin the mounting. Link to comment Share on other sites More sharing options...
