The Montana is a great choice and any of them 6xx will work but will be more of a long term investment.
A used garmin Zumo 660 or 660LM would be a good choice.
Finally, a new Garmin Oregon 550 can be used on a motorcycle. Oregon 450 as well (without the camera). A new in box unit is $350 and with a CNNT map and some mounting hardware, it will work both on the street, trail and hiking. It was the best in class unit for this prior to the arrival of the Montana 6xx series.
I recommend not buying any gps which uses the mini USB connector for power. That includes the Oregon/Dakota/Nuvi 500/550. Mini USB as a power source is far too fragile for long term motorcycle use.
