The Ohlins KT931 TTX RT rear shock is a dedicated rear mono shock for KTM RC8 and RC8R fitments, built around Ohlins’ track-focused damping architecture. It is designed to deliver controlled chassis behaviour under braking, turn-in and drive, with consistent damping feel as conditions change. This unit is supplied with an Ohlins spring already fitted.

Ohlins | Made to race, perfected to ride

TTX RT shocks are developed from Ohlins racing experience, with a focus on predictable response and repeatable adjustment. The KT931 is intended for riders chasing clearer feedback and more tunable rear-end control than a standard road setup.

Who this shock is for

• Track-day and race riders using KTM RC8/RC8R who want wider tuning range for grip and stability
• Riders looking to dial in rear support for braking and corner exit without harshness
• Owners who want a serviceable performance shock with a known setup baseline

Shock design & features

This is a gas-pressurised shock with oil and gas separated for consistent damping characteristics. It uses Ohlins’ TTX RT platform to improve damping control and stability when loads build quickly on track.

• Rear mono shock format for RC8/RC8R chassis
• Ohlins TTX RT internal architecture aimed at stable, predictable damping response
• Supplied with fitted spring (Ohlins 21040-24)

Tuning controls

The KT931 provides external damping adjustment for both compression and rebound, allowing you to tune support and grip to tyre choice, track surface and riding style. It is designed for independent control of these damping circuits so changes are easier to feel and validate.

Before you install

• Confirm the unit is matched to your exact KTM RC8/RC8R model and year, and check clearance around exhaust and linkage
• Set sag and basic geometry before making damping changes
• Record any changes you make so you can return to a known baseline if needed

Serviceability/lifecycle

As with all performance shocks, periodic servicing keeps damping consistent and protects internal components. Regular inspection and scheduled oil/seal service is recommended, especially for frequent track use.
