Don’t buy this compass for the Can-Am Spyder ST!!! I mounted one on the dash just above the instrument panel and it was a disaster. The dial actually spun like a top as I drove down the road, first in one direction and then the other, spinning so fast that I could hardly see the numbers. Even when the dial stopped for awhile, it moved back and forth a few degrees, never pointing in the real direction of my travel.
I’ve purchased a replacement at the local Walmart* store that actually was less expensive and points in the correct direction, plus it has a led light for night time trips!
