Well, after the roadbook holder wouldn't quite fit right on my 97' Adventure, I scrapped up some metal from a road sign (orange of course) and some thicker stuff from ones of those Razor scooter things.
No welding involved, just lots of drilling, screwing, grinding. It's not pretty. Just a nice minimalist setup. Hasn't vibrated apart so far. One problem is that the antenna is tucked under the dash a little so reception is harder to receive. Anybody know where those remote antennas can be found?
