• The Bridgestone BT39 is a bias ply tyre for sporty riding. Suited primarily to motorcycles in the 125cc to 400cc range, the H-rated BT-39 gives excellent dry grip and handling.
• The aggressive, race patterns ensure a large contact area at all lean angles for excellent dry grip. The open pattern design of the tread edges reduces shimmy whilst the center grooves give stability.
• The rear tyre uses a single crown radius for linear cornering performance.
