Peak engine performance is achieved at optimal coolant temperatures.

Unfortunately, like most motocross motors, the new-generation, fuel-injected CRF450R engine struggles to maintain its cool in less-than-optimal moto conditions such as threading the needle through technical wooded trails or pinning it down desert sand washes. At various levels, this can lead to overheating, short-term power loss, premature oil breakdown or worse.

To ward off these worries, FLUIDYNE® Powersports’ CRF450R radiators were developed to enhance low-air-flow riding conditions and provide consistent cooling in high-speed situations. Wider, deeper and more voluminous than stock, they have 42 percent more fluid capacity (799cc vs. 562cc) to significantly lower coolant temperatures and come with a stainless-steel radiator cap.

FLUIDYNE’s® new CRF450R radiators are also stronger and more durable than their OEM counterparts. Constructed from aircraft-quality aluminum, their structural improvements include a CNC-machined billet filler neck and beaded hose connections for leak-proof sealing. These components are held together with beefy TIG welds to withstand extreme conditions and produce a crash survival rate far exceeding OEM parts.

Not only do FLUIDYNE® Powersports’ new CRF450R radiators out-cool and outlast the stock units, they come with a one-year warranty and install in minutes, utilizing the factory mounts, hardware and protective louvers.

Winners in the 2009 Baja 500 Open Pro Motorcycle and Utility ATV classes, FLUIDYNE® Powersports radiators have been proven around the world. Developed and manufactured in the United States, they are built upon 50 years of experience in vehicular fluid dynamics.

Available for Honda’s CRF450R and other late-model dirt bikes, ATVs and side-by-side vehicles, they are sold through dealers nationwide.

When the heat is on, FLUIDYNE® Powersports radiators keep things cool. For more information, log on to
