H2O Performance Additional Water Radiator Kit Kawasaki ZX-10 R / ZX-10 RR (2011–2020)

H2O Performance has built its reputation on precision-engineered cooling solutions that keep high-revving superbikes at their peak — and this additional water radiator kit for the Kawasaki ZX-10 R and ZX-10 RR (2011–2020) is a testament to that heritage. Crafted with an enlarged core surface and an optimised fin structure, it delivers the thermal headroom your inline-four deserves, whether you're carving summer mountain roads, grinding through city traffic, or pushing hard on a trackday.

Key Features

• Enlarged radiator core with optimised fin geometry for significantly improved heat dissipation and reduced temperature spikes
• Designed to handle sustained high thermal loads — from stop-and-go commuting to full-throttle track sessions
• Precise, model-specific fitment for the ZX-10 R and ZX-10 RR across all 2011–2020 variants — no modifications required
• Plug-and-play installation as a supplement to the standard radiator, expanding total coolant volume and capacity
• Robust, long-life construction engineered to withstand the rigours of road, touring and circuit use
• Keeps the engine within its optimal temperature window, protecting cylinders, seals and cooling system components from thermal stress

Engineered for Performance, Finished to Last

H2O Performance has designed this kit with the same attention to detail that defines their wider cooling range. The enlarged surface area and high-density fin arrangement draw heat away from the coolant more efficiently than the stock setup, which means your ZX-10 R runs cooler under exactly the conditions that challenge it most — sustained high speeds, heavy traffic in summer heat, or the relentless demands of repeated track laps. The construction is purposefully durable, resisting the vibration and thermal cycling that degrade lesser aftermarket radiators over time.

Road, Tour and Track

This kit was conceived for riders who genuinely push their ZX-10 R or ZX-10 RR. On long touring runs where heat soak is a constant companion, the additional coolant volume smooths out temperature fluctuations and keeps the engine response clean and consistent across the entire rev range. On track, where the stock cooling system can approach its limits during repeated hot laps, the H2O Performance kit provides a meaningful thermal buffer — reducing the risk of heat-induced power loss and protecting the engine during the sessions that matter most. After installation you can expect more stable coolant temperatures, a smoother and more consistent engine note, better throttle response free from thermal flat spots, and greater overall confidence in the bike's reliability.
