The Ohlins STX 36 rear shock for the Honda MSX 125 (Grom) and MSX 125 (USA-Grom OG) is built to improve rear-end control and consistency in everyday riding and spirited use. It is a gas-charged, oil/gas separated design intended to keep damping stable as conditions change. This unit replaces the standard rear mono shock and is designed to be tuned to suit rider preference.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping quality, control and repeatability. On small-capacity bikes like the Grom, the rear shock plays a big role in traction, balance and confidence, particularly when road surfaces are uneven or grip is variable.

Shock design & features

  • STX 36 scooter shock architecture for rear mono applications
  • Gas-charged damping with separated oil and gas to help maintain consistent performance
  • Designed as a direct-fit replacement for the listed Honda MSX 125 models

Tuning controls

This shock includes external adjustments for rebound damping and compression damping, allowing you to refine how the rear responds to acceleration, braking and bumps. These controls are intended to help match the bike to your riding style and typical road conditions.

Base setup (factory preset)

The shock is supplied with an Ohlins baseline setting as a starting point. From there, rebound and compression can be adjusted to suit rider weight, tyre choice and the feel you are chasing, while keeping the bike balanced front to rear.

Before you install

Confirm fitment to Honda MSX 125 (Grom) and MSX 125 (USA-Grom OG) and check clearance around the shock body and adjusters. Installation should be carried out by a competent technician, with fasteners torqued correctly and the bike checked after initial rides.

Serviceability/lifecycle

Like all performance shocks, regular inspection and periodic servicing will help keep damping consistent. Keeping the shaft clean and addressing leaks or changes in feel early will support long-term reliability.
