The Ohlins KA503 TTX RT is a rear mono shock developed for the Kawasaki ZX-6RR, built around Ohlins’ TTX architecture for consistent damping behaviour under repeated hard use. It’s designed as a complete replacement unit, supplied with a fitted spring. This is a race-focused suspension component intended for riders who want predictable rear grip and support from a dedicated track shock.
