The H2O Performance additional water radiator kit for the R6 RJ15 (2008–2016) expands the factory cooling circuit directly, delivering dramatically improved heat dissipation and keeping coolant temperatures stable wherever the road or track takes you.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGreatly increased cooling capacity through an enlarged surface area and race-geometry fin structure\u003c\/li\u003e\n\u003cli\u003eSignificantly more stable coolant temperatures even under sustained hard riding\u003c\/li\u003e\n\u003cli\u003eExpanded thermal reserve for hot ambient conditions, high engine speeds and long track sessions\u003c\/li\u003e\n\u003cli\u003eProtection against overheating and heat soak — ideal for aggressive road use and trackday work\u003c\/li\u003e\n\u003cli\u003eConsistent power delivery maintained by keeping the engine away from thermal cut-back\u003c\/li\u003e\n\u003cli\u003eReduced thermal wear, extending engine service life over the long term\u003c\/li\u003e\n\u003cli\u003eWorks in parallel with the standard radiator — straightforward integration into the existing cooling circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAll-Day Confidence, Every Condition\u003c\/h2\u003e\u003cp\u003eRiders who spend long hours in the saddle — whether exploring demanding mountain routes, commuting hard in summer heat or completing back-to-back trackday sessions — know that temperature stability underpins every other aspect of the R6's performance. When coolant temperatures creep upward, throttle response softens, power delivery becomes inconsistent and the risk of heat-related damage rises. This H2O Performance kit addresses that vulnerability at the source, giving the R6 the thermal headroom it needs to perform at its best from the first corner to the last.\u003c\/p\u003e\u003cp\u003eThe enlarged fin geometry and increased core surface area work continuously alongside the original radiator, absorbing and dissipating heat more efficiently than the stock setup alone. The result is a calmer, more even engine note, crisper throttle pick-up and the confidence to push harder for longer without watching the temperature gauge creep toward the red.\u003c\/p\u003e\u003ch2\u003eBuilt for Sport, Engineered to Last\u003c\/h2\u003e\u003cp\u003eH2O Performance designs its radiator kits specifically for the demands of road sport and circuit use. The construction is robust enough to withstand the vibration and thermal cycling that come with aggressive riding, and the kit is precision-engineered to fit the R6 RJ15 airframe without modification. Installation works by expanding — not replacing — the factory system, so the original radiator remains in circuit at all times.\u003c\/p\u003e\u003ch2\u003eWho This Kit Is For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYamaha R6 RJ15 (2008–2016) owners who ride dynamically on road or track\u003c\/li\u003e\n\u003cli\u003eTrackday riders and club-level racers who need consistent cooling across multiple sessions\u003c\/li\u003e\n\u003cli\u003eSport touring riders covering long distances in warm conditions\u003c\/li\u003e\n\u003cli\u003eAny R6 owner who wants maximum reliability and sustained peak performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNoticeable Improvements After Fitting\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMuch more stable coolant temperatures under hard load\u003c\/li\u003e\n\u003cli\u003eSmoother, more consistent engine running\u003c\/li\u003e\n\u003cli\u003eImproved throttle response and more even power output\u003c\/li\u003e\n\u003cli\u003eReduced risk of temperature-related engine damage\u003c\/li\u003e\n\u003cli\u003eGreater overall riding confidence on road and track\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis H2O Performance additional water radiator kit is a direct-fit upgrade for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha R6 RJ15 — model years 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: H2O Performance\u003c\/li\u003e\n\u003cli\u003eType: Additional water radiator kit\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha R6 RJ15 (2008–2016)\u003c\/li\u003e\n\u003cli\u003eFunction: Supplementary radiator — expands factory cooling circuit\u003c\/li\u003e\n\u003cli\u003eFin design: Race-geometry, enlarged surface area for optimised heat dissipation\u003c\/li\u003e\n\u003cli\u003eConstruction: Heavy-duty, designed for sport and track use\u003c\/li\u003e\n\u003cli\u003eInstallation: Additive — works in parallel with the standard radiator\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"H2O","offers":[{"title":"Default Title","offer_id":53169031807242,"sku":"SY-ZUSATZLI-1E9394-01","price":30514.0,"currency_code":"THB","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/zusatzkuehlerr608-16.png?v=1780819720","url":"https:\/\/inter-pace.com\/en-th\/products\/h2o-performance-additional-water-radiator-kit-yamaha-r6-rj15","provider":"Inter-Pace","version":"1.0","type":"link"}
