The Ohlins KT1593 TTX 44 is a rear mono shock absorber developed for KTM off-road models where consistent damping control and clear chassis feedback matter. Built around the TTX twin-tube architecture, it separates working circuits to keep performance stable through long motos and rough conditions. Spring supply is separate, allowing the shock to be matched to rider weight and use.

Ohlins | Made to race, perfected to ride

Ohlins TTX technology is designed to deliver predictable damping behaviour and traction across changing track surfaces. The KT1593 is part of the TTX 44 family, aimed at motocross and enduro riders who want a more controlled rear end under braking, acceleration and square-edge impacts.

Who this shock is for

• Riders chasing improved rear-wheel connection and drive on corner exit.
• Motocross and enduro riders wanting a more tunable rear suspension package.
• Owners prepared to select a suitable spring separately to suit their setup.

Shock design & features

This shock uses a twin-tube (TTX) layout with oil and gas separated to help maintain damping consistency during hard use. The design supports stable pressure control and repeatable behaviour as temperatures and pace change.

Tuning controls

The KT1593 provides external adjustment for compression and rebound damping. These independent circuits let you fine-tune balance between support, comfort and traction without needing internal modifications for typical setup changes.

Before you install

• No spring is supplied; it is sold separately. Check the notes for the compatible spring series before ordering.
• Confirm fitment for your exact model and year within the KTM 125/150/250 SX, 250/300 XC (USA/CAN/AUS/NZ/MEX), 250/350 SX-F and 450 SX-F range.
• Plan your baseline setup after installation, then adjust compression and rebound methodically to suit terrain and pace.

Serviceability/lifecycle

Like all performance shocks, routine servicing helps maintain oil condition, seal integrity and damping accuracy over time. Use the recommended Ohlins shock oil listed for this unit during rebuilds.
