MOTORCYCLE SPECIFIC FEATURES :

The following features in GPR Motorcycle have been specifically designed to work with motorcycles:

• Onboard real time lean angle calculation from commonly available 3-axis IMUs (Bosch MM5.10, Yamaha R1, E Lean all currently supported).
• Ability to correct wheel speeds for variation in rolling tyre circumference due to lean angle.
• Wheelie detection by means of suspension position conditioning.
• Rider trim channels for traction control and engine braking.
• Engine braking strategy with open loop (throttle minimum position by gear and calculated engine speed) and closed loop (wheel speed differential with P controller) components. Utilises track sectors for enhanced performance.
• PID traction control by means of wheel speed differential and percentage slip. Multiple aim compensation and gain compensations available, including lean angle, longitudinal G, wheelie state and rider trim.
• Multiple throttle grip translation tables (engine speed v throttle grip position) selectable by gear position, rider switch and track sector.

• Gearbox shift request via up shift switch/down shift switch or gear lever force sensor.
• Gearbox shift control with ignition cut, fuel cut, ignition timing and throttle blipping.
• Launch control managing throttle limit and engine speed limit. Rider based entry with automatic exit based on gear position.
• Suspension Position Front and Rear.
• Rain light control strategy.
• Variable inlet length support (Yamaha R1, BMW S1000RR).
