Dirt Bike Fuel Systems

If you're anything like us at MotoSport, you want as much power out of your dirt bike as you can get! So you change out the dirt bike exhaust, air filter, maybe you've even had some motor work done. Now it's time to put all of your dirt bike modifications to good use, which means taking a look at the fuel injection and ignition controlled by your ECU, which is basically your bike's computer. In our "Fuel Management" section, we have piggyback ECUs that plug in-line with your stock computer, the result being that you can now change your fuel map to coax that last horsepower out of your dirt bike, dial it in for race gas, optimize it for the current weather conditions, and much more. Some of them can be upgraded with a handlebar-mounted switch to change between fuel/ignition maps at the press of a button.
