H2O Performance Water + Oil Radiator Kit – Honda CBR 1000 RR (2012–2019)

Engine temperatures you cannot control are a safety risk, not just a performance concern. The H2O Performance Water + Oil Radiator Kit for the Honda CBR 1000 RR (2012–2019) is engineered to keep both coolant and oil temperatures in a stable, safe operating range under every condition — from a spirited road ride to a full trackday assault. If you demand consistent, reliable protection from your CBR's cooling system, this combined kit is the definitive upgrade.

Key Features

• Combined water and oil radiator kit designed as a matched system — both coolers tuned to work in harmony for the CBR 1000 RR platform
• Optimised cooling surface area and efficient heat dissipation reduce the risk of thermal stress and heat soak under sustained hard use
• Stabilises oil temperature for consistent lubrication quality, protecting engine internals on long runs and back-to-back track sessions
• Eliminates thermally induced power loss — steady operating temperatures mean the CBR delivers its full performance across the rev range at all times
• Retains the existing cooling circuit architecture, making this a direct upgrade rather than a full system replacement
• Built from quality materials with robust construction suited to both road and circuit environments

Why Thermal Safety Matters on the CBR 1000 RR

The Honda CBR 1000 RR is a superbike that rewards hard riding — but the factory cooling system was designed with average use in mind. Trackdays, aggressive road passes in summer heat, or laden touring in traffic push coolant and oil temperatures into territory where the standard radiators begin to struggle. Elevated oil temperatures thin the lubricant film, increasing wear on bearings, piston rings and the valvetrain. Coolant temperatures that cycle too high trigger fuelling corrections that blunt throttle response and flatten peak power. The H2O Performance kit addresses both problems simultaneously, giving you a thermal safety margin that the OEM setup simply does not provide.

On Road, On Track

Once fitted, the difference in engine behaviour is immediately apparent. Operating temperatures remain steady even during queuing at pit lane, slow traffic in warm weather, or the final laps of an evening trackday when ambient temperatures are still high and the engine has been working hard for hours. The result is a CBR that feels calmer, pulls cleanly from lower in the rev range and — most importantly — one you can trust not to put you in a difficult situation because of thermal overload. Whether you are a track-focused rider chasing consistent lap times or a sporting tourer covering serious mileage, this kit raises the reliability ceiling of your machine.
