Hi there,

The reason only the Drivesmart Pro is used for motorcycles is because it is not required to be outward facing (as it uses a GPS database rather than any live detection).
The Evo and Alpha will need to have a view of the road to pick up radar / laser signals via the front sensor.  So if you can find some way of mounting it on your motorcycle, and waterproofing / powering it, then it may be an option - but not something we offer unfortunately.
