The rake angle is set at 26 degrees, and the trail measures 3.8 inches. These geometry values contribute to stable steering and predictable handling. The total running weight is 1,184 pounds, and the gross vehicle weight rating is 1,700 pounds. The front axle rating is 511 pounds, and the rear axle rating is 1,189 pounds, reflecting the load distribution across the trike platform.
Suspension System and Ride Control
The front suspension uses a 49 millimeter dual bending valve fork with 4.6 inches of travel. This fork design improves damping control by separating compression and rebound forces, resulting in more consistent front-end behavior. The rear suspension consists of hand-adjustable emulsion shocks with 3.5 inches of travel. These shocks allow preload adjustment based on rider weight and cargo load.
Suspension tuning is configured to balance ride comfort and handling stability. The front and rear travel measurements support absorption of road irregularities while maintaining consistent tire contact.
