New Technologies

• Electronic Braking System (EBS)

• Air Dryer

• LED Headlights/Taillights

• Steerable Rear Axles

• Exhaust Vibration Balancer

EBS

• Uses electronics to control braking system

• Reduces number of components

• Detects brake wear

• Shortens stopping

distance

Air Dryer

• Protects braking system from moisture and contamination

• Weighs 11 pounds

• Water absorption

• High reliability

LED

• Low heat, High efficiency

• Vibration sensitivity

• Multi-Color capability

• Covert communication

• Used on ST II

All Steer

• Improves maneuverability

• Automated, user operated

• Improves turning

radius by 30%

Exhaust Vibration Balancer

• Balances vibration, torque and road shock

• Reduces fuel consumption

• Reduces failure

• Increases durability
