Trail Tech Digital Fan Kit - Product Of The Week


(360) 687-4530

This Product Of The Week is one of our favorite bike accessories and has been part of our Product Of The Year articles in the past. Here is a our first test of Trail Tech's Digital Fan Kit, which received a 93 – not an easy task! Since this test took place in 2014, the fan kit currently fits more models including the Yamaha YZ250FX. Check out for all applications.

Not all off-road bikes come with an electric cooling fans, but they probably should! There isn’t a bike that doesn’t boil over and blow steam when abused at slow speeds. Trail Tech makes a fan kit to fit the 2008-2014 KTM XC-F, XCF-W/EXC four-strokes and 250/300 XC/XC-W two-strokes. They also make a kit for the Honda CRF40X. We chose to test the kit on our 2014 KTM 350 EXC and installation took less than 30 minutes. A little tip is to drain enough coolant to loosen the top radiator hose and simply pull the radiator away from the frame, leaving the lower hoses attached. I was able to easily mount the fan bracket with the four provided bolts that go into existing holes in the stock radiator without completely removing the radiator from the bike. If your bike doesn’t have an empty electrical plug off the wiring harness (many KTMs have an extra plug open) to directly plug the Trail Tech fan into you can use the provided straight-from-the-battery wiring harness. I chose to try out the wiring harness and it was quick and easy to hook to the battery, and it has an inline fuse. A nice bonus to the Trail Tech fan is the temperature sensor simply pushes between cooling fins with the help of electrical grease, you don’t have to use the temp sensor plug provided on some radiators or tap into existing cooling lines.

Having spent many hours on the 350 EXC with and without a fan I can tell you a fan is mandatory equipment. Without one the 350 boils and spits quickly, especially in slow terrain. A feature of the Trail Tech fan is that you can choose the temperature at which the fan turns on, and we found 175 degrees to be a good number. Only once did I have the 350 boil over and steam after a grueling first gear, clutch-slipping climb. The fan helped get the temperature back down quickly without loosing much coolant. Keeping your engine from overheating and running hot is a great way to improve longevity. The Trail Tech digital fan kit weighs about 1.5 pounds and is worth every ounce.
