My bike has 91,563 km on it now. The old safety switch is a totally different design and not easily switchable with the new unit. The new Clutch master has a tiny box- type micro switch, rather than the small plunger-cylinder on the stock unit. I'll try to get some comparison pictures for you. Clipping the wires and a little solder and shrink tube takes only as long as the soldering iron does too heat. It is very easy, so I wouldn't bother trying to swap the switches. The new unit has a super easy and smooth feel compared to my old stock unit. I like using my clutch again.
