The Ohlins MG333 STX 46 Street is a rear mono shock developed for road riding where consistency and control matter. It uses a pressurised, oil/gas separated damping layout to help maintain stable damping behaviour as conditions change. Built around Ohlins’ proven STX architecture, it’s intended for riders who want a more tunable rear end without compromising day-to-day usability.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are engineered with the same damping principles used across their competition programmes, adapted for real-world roads. The focus is predictable grip, clear feedback and adjustability that actually translates to better balance. This unit is designed as a direct-fit replacement for the original rear shock position.

Who this shock is for

Suited to Moto-Guzzi MGS owners chasing improved stability and a more controlled feel through corners and over imperfect surfaces. It’s a strong match for riders who want to fine-tune rear ride quality and chassis balance for their weight, tyres and typical roads.

Shock design & features

This is an STX 46 Street rear shock with a pressurised, oil/gas separated design (not an emulsion shock). The separation of oil and gas supports more consistent damping response during extended riding and under repeated suspension movement. The layout is intended to deliver good sensitivity while maintaining support as loads build.

Tuning controls

Adjustment is provided for rebound damping and compression damping, allowing you to tune how quickly the shock extends after a bump and how it controls movement under impacts and load changes. Spring preload adjustment is also included to set sag and ride height balance.

Before you install

• Set rider sag with preload before fine-tuning damping; this establishes the baseline chassis balance.
• Make one change at a time and keep notes so you can track what improved (or worsened) the feel.
• If your use case or load varies (solo vs luggage), plan for a quick check of sag and damping to suit.

Serviceability/lifecycle

Like all performance shocks, periodic servicing helps keep damping consistent and protects internal components. A refresh typically involves oil replacement and inspection of wear items, which is especially worthwhile if the bike is ridden regularly or in harsher conditions.
