These switches take a beating from weather and years of thumb use, so if the one on your bike is cracked, sticky, or the contacts inside are worn out, it's a straightforward swap rather than a repair job. Check your own switch housing and wiring runs before ordering to make sure this matches what's on the bars now.
We've seen this part turn up new-old-stock, still in the original box from the factory, so condition can vary if you're sourcing one secondhand. Give us a call if you want to talk through fitment before you buy.
