Febur Racing Water and Oil Cooler for Kawasaki ZX-10 R/RR (2021-2026) FE1594S

When tenths of a second and engine longevity are both on the line, the quality of your cooling system is non-negotiable. The Febur FE1594S racing water and oil cooler is engineered from premium materials with a precision-optimised surface structure that keeps the Kawasaki ZX-10 R and ZX-10 RR running at the ideal thermal window, whether you are chasing lap records or covering serious road miles.

Key Features

• Optimised surface geometry draws heat away from coolant and oil with maximum efficiency, eliminating the temperature spikes that sap power and accelerate wear.
• Premium-grade construction materials chosen for thermal conductivity, mechanical strength and long-term reliability under sustained racing loads.
• Stabilised coolant temperature keeps the engine in its optimal operating range, preserving peak power output even on hot track days or in heavy summer traffic.
• Combined water and oil cooling in a single race-developed unit reduces complexity and weight compared to running separate aftermarket coolers.
• Proven in top-tier competition — Febur cooling systems are trusted by Puccetti Racing, Barni Racing, Go Eleven, MV Agusta Reparto Corse and other leading WorldSBK teams.
• Direct-fit replacement designed specifically for the 2021-2026 ZX-10 R and ZX-10 RR chassis, ensuring a clean installation without fabrication or modification.

Build Quality and Materials

Febur's reputation in the WorldSBK paddock rests on an uncompromising approach to materials selection and manufacturing precision. The FE1594S uses high-grade alloys throughout its core and tank construction, delivering a thermal capacity and structural integrity that OEM coolers simply cannot match at race pace. The specially developed surface structure — a hallmark of Febur's race programme — increases the effective heat-transfer area without adding bulk, allowing the cooler to manage extreme heat loads that arise during sustained high-rpm running. Every unit leaves the factory to the same specification demanded by factory-supported race teams, so the cooler you bolt to your ZX-10 R is built to the same standard as those on the Superbike World Championship grid.

Performance and Thermal Control

Consistent engine temperature is one of the most overlooked factors in both outright performance and long-term reliability. Overheating, even momentarily, causes power delivery to drop, accelerates oil degradation and puts internal components under unnecessary stress. The FE1594S addresses this by providing a significantly enhanced cooling capacity over the standard item, keeping water and oil temperatures stable during back-to-back sessions on track or in demanding real-world riding conditions. The result is an engine that responds predictably, makes full use of its fuelling and ignition maps, and suffers less thermal wear over its service life.
