Yesterday's video shows the motorcycle taking off and accelerating to 140 kilometres per hour in less than 20 seconds on Highway 7 near Hope, British Columbia.
A young black bear that appears to have been spooked by a train running parallel to the road suddenly darts into view and collides with the bike.
Police said in a statement that the driver was focused on his speedometer as part of a stunt and failed to see the bear until the last minute.
