The Ohlins STX 36 Blackline rear shock is designed as a suspension upgrade for the Vespa Sprint 150 ABS, focusing on controlled damping and consistent support. It combines a classic external finish with modern internal valving to improve stability and ride comfort. This unit is built to be tunable, so you can match the feel to your load, roads and riding style.

Ohlins | Made to race, perfected to ride

Ohlins shocks are developed with a clear engineering focus: predictable damping behaviour, repeatable adjustment, and serviceable construction. The STX 36 platform is widely used across street applications where comfort and control both matter. The Blackline finish suits builds where appearance is part of the brief, without compromising function.

Shock design & features

• STX 36 rear shock architecture.
• Oil and gas are separated to help maintain damping consistency during use.
• Blackline styling intended to complement classic and custom scooter builds.

Tuning controls

• Spring preload adjustment to set ride height and support for rider/passenger/load.
• Rebound damping adjustment to control how quickly the shock extends after a bump.
• Compression damping adjustment to tune firmness and bump absorption on impacts.

Base setup (factory preset)

This shock is supplied with an Ohlins baseline setting intended as a starting point. From there, adjust preload first for correct support, then refine rebound and compression to suit your roads and preference. Small changes with test rides between adjustments will help you find a balanced setting.

Before you install

• Confirm fitment for Vespa Sprint 150 ABS and check that the mounting hardware and clearances match your scooter.
• Inspect bearings/bushings and mounting points before installation, as worn mounts can mask suspension improvements.
• After installation, re-check fasteners and verify that the shock moves freely through its travel without interference.

Serviceability/lifecycle

This Ohlins unit is built to be maintained rather than treated as disposable. Periodic servicing helps keep damping performance consistent and extends component life, especially if the scooter is used in wet or dusty conditions or carries extra load frequently.
