The Lainer IMPACT16 is a complete rear shock absorber assembly designed and manufactured by Lainer Suspension Racing for the Beta X Trainer 250 and 300. It is supplied as a shock body (spring not included), allowing you to select the correct spring separately. This shock is intended for riders wanting a purpose-built replacement with adjustable damping controls.

Built For Real-World Suspension

A rear shock should be replaced when the existing unit is leaking, has inconsistent damping, or no longer responds correctly to adjustment. If your current shock is performing correctly and can be serviced, a rebuild may be the appropriate option rather than replacement. The IMPACT16 is a complete shock option where a full assembly is required.

Inside the System

• 50 mm ergal piston with FRK band
• 16 mm stem

Adjustment & Setup
