The BR was made for work purposes only (or what it was designed for) so trail riding wasn't a strong point of it. The Pioneer is more of a sport/utility with a little narrower wheel base, more suspension travel, different shift maps for the transmission. Besides looks they changed other things like mounting the engine on it's own sub frame (less vibration and quieter cab, exhaust is extended back farther so again, less noise. Once you start picking them apart there is a lot different even though they are based off of the same driveline/powerplant.
