watch out on the one for Royal Enfield, the arm that actuates the switch may be the mirror image of the one you need. I have the original one for my 1960 A10. The switch still works, the lever is a mess, it needs a new rubber boot, and while I can get it to work on the bike I have no faith that it would do so reliably. I bought one of those "universal" ones on Ebay for around 7 dollars and although right now it's still in the wrapper, next spring it may not be! Don't know about any brake pedal changes.
