The 2007 Sportsters join the rest of the line by incorporating Harley's ESPFI fuel injection as standard equipment, a move no doubt required by impeding emissions standards. However, fuel injection also brings more immediate benefits. The four Sportster XL 883 models have about 15 percent more torque at 2500 rpm as a result of the changes made with the new induction. To accommodate the new system, which will doubtless bring improved driveability as well as cleaner exhaust gases, Harley-Davidson redesigned the Sportsters' rear fenders, seats, fuel tanks, coils, stators, exhaust pipes, wiring and induction system, and revised the frame. Oxygen feedback acts independently on each cylinder, so the system "learns" and adjusts to changing conditions to deliver optimal performance. Also new this year are new gauges with a clock included in odometer LCD, a low-fuel warning light and two tripmeters. It also gets an eight percent reduction in clutch lever effort and an 11 to 14 percent reduction in front brake lever effort, depending on model. Two-inch lengthening of handlebar wiring make bar swaps easy.
