The Ohlins YA761 STX 46 Street is a rear shock absorber built to improve control, stability and tyre contact on the Yamaha Spark / RX 135i. It uses race-derived damping architecture refined for street riding, with a focus on clear feedback and predictable support. This unit is designed to be tuned around your load, riding style and road conditions.

Ohlins | Made to race, perfected to ride

Ohlins STX technology is developed from competition suspension principles and adapted for everyday use. The aim is consistent damping behaviour and better chassis composure through typical street inputs like braking, acceleration and mid-corner bumps. This rear unit is intended as a complete replacement shock for the OEM mono setup.

Who this shock is for

• Riders who want more stable rear ride behaviour under braking and acceleration
• Owners setting the bike up for mixed street use where grip and feedback matter
• Anyone looking for a tunable rear shock rather than a fixed, non-adjustable replacement

Shock design & features

This is an STX 46 rear shock with a gas-pressurised, oil/gas separated damping system to help maintain consistent damping during longer or harder rides. The internal layout is designed to deliver controlled movement with good sensitivity to road texture, helping the rear tyre stay planted.

Tuning controls

This shock provides rebound damping adjustment and compression damping adjustment, allowing you to tune how quickly the shock extends after a bump and how it resists compression under load. It also includes spring preload adjustment to set ride height and sag for rider weight and typical carrying load.

Before you install

• Confirm fitment for Yamaha Spark / RX 135i and rear mono mounting before booking installation
• Set preload first to establish correct sag, then fine-tune rebound and compression to suit grip and comfort
• Check linkage and mounting hardware condition during installation, as worn pivots can mask shock performance

Serviceability/lifecycle

As an Ohlins unit, the YA761 is designed to be serviced and reconditioned, with wear parts and oil replaced as required to keep damping consistent over time. Regular servicing based on use conditions helps maintain performance and reduces component wear.
