Whether dual-sporting, pavement pounding or roosting in the dirt, excess heat is the enemy of consistent four-stroke engine performance and reliability. That’s why FLUIDYNE Powersports builds radiators for Suzuki’s entire DR-Z400 lineup: the SM-designated Supermoto, S-model dual-sporter and the dirt-only DR-Z400.
These radiators keep Dr. Z’s do-it-all Thumper motor properly cooled in less-than-optimal conditions that can lead to overheating, short-term power loss, premature oil breakdown or worse.
These beefy units were developed to enhance low-air-flow riding conditions and provide consistent cooling in high-speed situations. Boasting 50 percent more cooling surface area than stock and an astounding 67 percent greater fluid capacity, the FLUIDYNE units significantly lower the DR-Z’s coolant temperatures.
FLUIDYNE’s DR-Z radiators are also stronger and more durable than their OEM counterparts. 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 parts.
Not only do FLUIDYNE® Powersports’ DR-Z radiators out-cool and outlast the stock units; at $249 per side, they cost less, too. All come with a one-year warranty and install easily (even with aftermarket fuel tanks), utilizing the factory mounts and hardware. The SM-specific application has cooling-fan mounts on the left-side radiator and a threaded fitting on right-side radiator for the motor’s fan switch.
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 the entire DR-Z400 lineup and other late-model motorcycles, ATVs and side-by-side vehicles, FLUIDYNE Powersports radiators are sold through dealers nationwide.
