Motorcycle mechanics specifics

[Elver]

How do motorcycles mechanically perform in roles aside from movement? Movement, they're definitely Wheeled. I assume for terrain +attack/defense/entrenchment they're Infantry. I'd further assume they benefit from Infantry Tactics and Mobile Tactics OHQ skills. But what about postures? It feels like what would make the most sense would be if they took on Mechanized offensive & AP modifiers and Infantry defensive modifiers, but I suspect they're instead just all one or the other. Does anyone know for sure how motorcycles get treated?

They are infantry for all purposes, just have a Wheeled move type.
