Fluidyne Powersports


SAN BERNARDINO, Calif. (August 13, 2009) - Race-bred for battle on rough-and-tumble motocross tracks, in wicked Eastern woods and wide-open Western terrain, the YFZ450R's motor generates major heat while powering toward the podium.

Excess heat is the enemy of consistent four-stroke engine performance and reliability. FLUIDYNE® Powersports' YFZ450R radiator keeps this fuel-injected Thumper properly cooled in less-than-optimal conditions that can lead to overheating, short-term power loss, premature oil breakdown or worse.

This beefy unit was developed to enhance low-air-flow riding conditions and provide consistent cooling in high-speed situations. Boasting taller fins and a deeper core, it has 40 percent more fluid capacity to significantly lower coolant temperatures.

FLUIDYNE's® new YFZ-R radiator is also stronger and more durable than its OEM counterpart. Constructed from aircraft-quality aluminum, structural improvements include thicker materials throughout, a CNC-machined billet filler neck, beaded hose connections for leak-proof sealing and a stainless-steel radiator cap rated at 16 lbs. These components are held together with beefy TIG welds to withstand extreme conditions and produce a crash survival rate far exceeding the OEM part.

Not only does FLUIDYNE® Powersports' YFZ450R radiator out-cool and outlast the stock unit, it comes with a one-year warranty and installs easily, utilizing the factory mounts, hardware and fan assembly.

Winners in the 2009 Baja 500 Utility ATV and Open Pro Motorcycle 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 the YFZ450R and other late-model ATVs, side-by-side vehicles and motorcycles, FLUIDYNE® Powersports radiators are sold through dealers nationwide.
