H2O Performance EVO Water + Oil Cooler Kit for Honda CBR 1000 RR-R SC82 (2020–2026)

The Honda CBR 1000 RR-R SC82 is one of the most potent production superbikes ever built — and that ferocity generates heat that the standard cooling system was never designed to handle at sustained race pace. H2O Performance's EVO Water + Oil Cooler Kit was engineered from the ground up to address exactly that: a matched pair of oversized, race-geometry coolers that work in concert to keep your Fireblade's temperatures firmly under control whether you're threading Alpine passes or pushing hard through a track day session.

Key Features

• EVO oversize water radiator with enlarged core surface area and race-optimised fin geometry for significantly greater heat dissipation
• EVO high-performance oil cooler with improved oil circulation and faster thermal transfer, protecting against oil film breakdown and oil dilution under sustained load
• Dual-circuit design — water and oil cooling circuits developed to complement one another, delivering measurably lower and more stable temperatures across both systems
• Premium aluminium construction: lightweight, rigid and built to withstand the thermal cycling of repeated track use
• Higher coolant flow rate compared to the OEM system, eliminating heat soak during slow sections, queues and summer traffic
• Direct OEM replacement fitment — replaces or extends the standard system without complex fabrication or modifications

Design, Finish and Heritage

H2O Performance has been developing purpose-built cooling solutions for competition and high-performance road use for years, and the EVO range represents the pinnacle of that work. The EVO designation signals a genuinely evolved product: the fin pitch, core depth and tank geometry have been refined over multiple development cycles to optimise airflow and coolant velocity simultaneously. The aluminium construction carries a clean, purposeful appearance that suits the SC82's aggressive aesthetic — this is hardware that looks as serious as it functions.

Where many aftermarket radiator kits address only the water circuit, the EVO package treats the cooling system as a whole. The oil cooler is not an optional add-on but an integral part of the system, sized and positioned to work with the water radiator rather than independently of it. The result is a thermally balanced powertrain that maintains consistent oil viscosity and water temperature even during the longest, hardest stints.

On-Road and Track Performance

Fit the EVO kit and the changes are tangible from the first ride. Water and oil temperatures drop and, crucially, they stay stable rather than climbing progressively through a session. There is no heat-related power loss on long straights, no ragged throttle response from an overheated engine, and the quickshifter behaviour becomes noticeably more consistent because the drivetrain is operating in its intended thermal window. Reduced thermal stress on seals, lubricants and internal components also translates directly into longer service intervals and extended engine life — a worthwhile return on a premium cooling investment.

What You Will Notice After Installation

• Significantly lower water and oil temperatures at all riding intensities
• Consistent power delivery lap after lap, with no heat-induced drop-off
• No heat soak during slow traffic or at the end of a straight
• Smoother, more even engine behaviour throughout the rev range
• Reduced thermal loading on seals and lubricants
• Greater confidence and composure during hard, sustained riding

Fitment and Compatibility

This kit is developed specifically for the Honda CBR 1000 RR-R and CBR 1000 RR-R SP (SC82 chassis), covering model years 2020 through to 2026. It is designed as a direct replacement for the OEM cooling components and requires no cutting, welding or custom fabrication. Suitable for road use, trackdays and professional racing.
