There are two major schools of thought about motorcycle suspension, solid axle versus independent suspension
Traditionally, the solid axles trikes have offered good handling but a harsh ride.  Independent suspension trikes have offered a plush ride but poor handling.

The fully independent Hannigan Trike utilizes several unique approaches  to maximize both handling and ride: wide-track suspension, IAS shocks , and a stabilizer bar.

Some independent suspension systems use A arms which only allow the wheel to move in a vertical
direction. The Hannigan twin trailing arms allow the wheels to back and away from the bump resulting in a cushier ride. 

Sooner or later air shocks and other suspension components utilizing air pressure will begin to leak or fail altogether, resulting in  poor handling. Also air shocks require regular monitoring and are not user-friendly. Instead, Hannigan Trikes utilize dual Progressive Suspension IAS Shocks ( Inertially Activated System) with dual spring loaded pistons. That can sense when the seat  compresses down and when the swing-arms compress up.  The shocks automatically change valving to reduce impact to the seat. In a Trike application they contribute to a more stable ride by minimizing negative lean in hard cornering.

Our 60-inch wide track and sports car-style stabilizer bar have resulted in one of the safest  and most stable trikes available.  In head to head comparison tests the Hannigan trike out-handles the best of the solid axle trikes while offering a ride that is judged superior by the vast majority of riders.
