Prime 9™ Technology is a counter-intuitive philosophy based on the less is more theory. It embraces range without adding complexity. The outcome is fewer parts, reduced weight, and increased durability.

Oversized™ Technology is a philosophy of design and engineering. Its goal is to reduce energy loss to deformation or flex. The results are enhanced control, better acceleration, and increased speed.

Stealth™ Technology is a philosophy of eliminating power loss by providing instant torque to the wheels. The result is Infinite Points of Engagement, Instant Power Delivery, and Silent - Low Drag Coasting.
