I looked into the wireless ones. But on a motorcycle, the sender needs to be farther from the guage than on a bicycle. I had to add a section into my sender wire so it would reach from sender to guage. It's probably 36 inches long now. On a bicycle the sender can mount high on the front forks near the handlebars, but on a motorcycle it needs to be mounted down low near the hub.I think a backlit one would only be feasible if it used your bikes electricity for the lighting. If you were to rely on the guages battery for the lighting I think you would be changing batteries a lot. Of course ... I could be wrong, it's happenned before.
