The Ohlins YA359 is a rear mono shock for the Yamaha YZF R1, built around Ohlins TTX architecture for consistent damping behaviour and clear chassis feedback. This unit uses a gas-charged, oil/gas separated design to help maintain damping control as temperatures and pace change. Designed for riders who want a proper tuning range for track work and fast road use without sacrificing predictability.

Ohlins | Made to race, perfected to ride

TTX is Ohlins’ twin-tube damping concept, developed from racing and refined for real-world ride quality. The layout is intended to keep damping response stable and give you repeatable changes when you adjust the settings.
