KTM’s groundbreaking lineup of middleweight thumpers are serious, competition-ready machines, but their thin, perilously located radiators can suffer from boiling over and succumb to crash damage.
While racing or in trail-attack mode, this can lead to overheating, short-term power loss, premature oil breakdown or worse. That’s why Fluidyne Powersports developed stronger, more efficient radiators for KTM’s entire family of mid-sized, 350cc and 250cc four-strokes. This performance and durability upgrade keeps their motors at optimum temperatures in low-air-flow riding conditions and provides consistent cooling in high-speed situations. Compared to stock KTM radiators, the Fluidyne Powersports units boast 30 percent more fluid capacity due to their highly efficient, 38mm cores which significantly lower coolant temperatures, and are built tougher to fend off unfortunate meetings with Mother Earth.Fluidyne radiators are constructed from aircraft-quality aluminum. Structural improvements over the OEM units include thicker tanks and side plates, a CNC-machined billet filler neck, beaded hose connections for leak-proof sealing and a stainless-steel radiator cap rated at 21 lbs. These components are held together with beefy TIG welds to withstand extreme conditions and produce a crash survival rate far exceeding the stock parts.Not only do Fluidyne Powersports’ radiators out-cool and outlast the KTM units, all come with a one-year warranty and install easily (even with aftermarket fuel tanks), utilizing the factory mounts and hardware.Powering SCORE and Best in the Desert series champions, who have scored wins in the 2010 Baja 1000, multiple Baja 500 and the grueling, 1000-mile Vegas-to-Reno race, 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 KTM’s entire lineup of off-road bikes Fluidyne Powersports radiators are distributed by Parts Unlimited, Tucker-Rocky, WPS, KK Motorcycle Supply, MTA, Southern Motorcycle Supply, CV-4 and IMS Products-making them readily available through thousands of dealers nationwide.When the heat is on, Fluidyne Powersports radiators keep things cool.For more information, log on to FluidynePowersports.com.
