I am amazed at all these posts above, as no-one mentions switching-temperature?
Goodluck mounting one with a higher temp!
Also, any automotive parts shop will have a catalogue of these things, and there's a few cars (some Suzuki) which have the exact-fit switch.
Better still, this catalogue also lists the switching temperature, pick & choose.
Best, they're very cheap, contrary to bike part prices or the daylight=robbery price of Rally Raid!
It seems I have to do this, as quite frankly the info on this thread is useless.
