Got a 2 Husaberg 390, 450 or 570? Then you know that the only thing missing from this fantastic bike is some extra fuel to extend your day on the trail, or complete that long race loop with confidence!! Enter the 70 Degree Racing Sub Frame Fuel tank!! Made right here in the U.S.A., from the same tough XLPE plastic (Cross Linked Polyethylene) as your stock sub frame, our Sub Frame tank replaces your stock Husaberg subframe unit in about an hour, providing you with an extra 1 gallon of fuel in addition to the 2.2 gallons the stock tank holds. Since our Sub Frame tank is translucent, and works in tandem with your main tank, you will always be able to gauge how much fuel you have left in that stock black gas tank. Gone are the days of having to guess how much fuel you have left, and relying soley on the low fuel light to let you know when your getting low on fuel. All mounting hardware, and an easy to read instruction guide are included with our tank. Due to an extremely large order, we are now back ordered for the sub-frame tank for 4 to 6 weeks. Our 2012 Model will be available then. Improvements include stainless steel inserts and natural (white) in color.
