"The motorcycle track at the Motorplex is the inner track seen in the photo's. Its approximately 460m in length (the outer car track is 520m), keeping in tradition with tracks in Western Australia generally being larger than other Aussie tracks (the old Claremont Speedway was 550m in length)."

"Just to add, the Perth Motorplex at Kwinana was opened in 2000 and incorporates the Perth Motorplex Speedway and the Perth Motorplex Drag Strip. Motorcycle speedway rarely takes place at the Motorplex, with most major events for solo's and sidecars run at the 142 metres (155 yards) Pinjar Park, north of the city near the Wanneroo Park motor racing circuit."
