Öhlins FGRT 225 Upside Down Fork Road & Track – Kawasaki ZX-10R / ZX-10RR (2016–2020)

The Öhlins FGRT 225 is a full upside-down fork assembly engineered for riders who demand all-day confidence whether threading a technical road section or chasing lap times on circuit. Carrying the proven Öhlins 30 mm cartridge kit already race-validated in national Superbike championships, it delivers a composed, communicative ride that stays compliant over long stints without sacrificing the precision you need at the limit.

Key Features

• Öhlins 30 mm cartridge kit — the same internals trusted in national Superbike championships — delivers deep, consistent damping whether you are on a weekend road ride or a track day.
• Independent compression and rebound adjustment lets you dial the fork to your weight, tyre choice and circuit conditions without compromise.
• 120 mm of travel with a 10.5 N/mm spring rate strikes a balance between plush compliance on long rides and taut responsiveness under hard braking.
• Upside-down architecture reduces unsprung mass for sharper turn-in response and improved braking stability under heavy deceleration.
• Road & Track type code confirms the fork is designed to perform on both public roads and the circuit, not a pure-race fitment that sacrifices everyday usability.
• Race-grade build quality housed in an Öhlins finish — a direct aesthetic and functional upgrade over the OEM Kawasaki fork assembly.

Performance & Build Quality

At the heart of the FGRT 225 is the Öhlins 30 mm cartridge system, a platform refined through seasons of top-level Superbike competition. The cartridge controls oil flow independently on compression and rebound, so you can soften the fork for a smooth A-road session in the morning and firm it up for the afternoon track session without reaching for a wrench — just the external adjusters. The 08790-series spring (part number 04744-05) is matched to the fork's 10.5 N/mm rate, providing a progressive feel that loads progressively through a corner rather than diving sharply under braking.

The inverted architecture keeps the heavier, larger-diameter lower leg fixed to the frame while the lighter upper tube moves with the wheel. The result is a measurable reduction in unsprung weight compared to a conventional right-side-up fork, translating into faster wheel tracking over surface irregularities and a more planted front end when you push hard into a late-braking zone.

Road & Track Versatility

Unlike dedicated race forks that sacrifice compliance for outright stiffness, the FGRT 225's Road & Track designation means the spring and valving are calibrated to cope with real-world surface variation. Over a full day in the saddle the damping stays consistent as oil temperature rises, so the fork behaves the same on lap twenty as it did on lap one — a quality that pays dividends in rider fatigue as much as in lap time.

Fitment & Compatibility

The FGRT 225 is a direct fitment for the following Kawasaki models. Note that ABE type approval is in preparation for Germany — please confirm the current homologation status before road registration.

• Kawasaki Ninja ZX-10R (2016–2020) — ABE in preparation (Germany)
• Kawasaki Ninja ZX-10RR (2018–2020) — ABE in preparation (Germany)

Important: this fork is not compatible with the 2018/2019 SE (semi-active suspension) variant of the ZX-10R or ZX-10RR.
