Pusher

Puster was supposed to be electric, but he didn't. However, when looking for a better frame, the Pusher is available as such with a 20 hp internal combustion engine.
So the pusher is the Buster XSr of the 2014 model year, except it isn't, because that's when Buster was making the same boat as well as drive-branded.

You can book a Puster through Skipper.
