The 2018 Harley-Davidson Softail Fat Bob has a starting suggested retail price of $16,999 and is available in five colors, Vivid Black, Black Denim, Red Iron Denim, Bonneville Salt Denim or Industrial Gray Denim. Powering this American machine is an air-cooled, single cam driven, 107ci v-twin.
Our Fat Bob got some performance upgrades from Screamin’ Eagle. We installed their Satin Black Street Cannon Mufflers, paired with their Satin Black 4.5” end caps (sold separately) along with their High-Flow Air Cleaner Kit with Ratchet Round Cover (sold separately). To tie it all together we used their Pro Street Tuner to remap the ECU.
We ran the Fat Bob with the Stage I upgrades on our rear-wheel dyno in fourth gear to determine peak output from the hopped-up v-twin. We documented 83.59 hp at 5,200 rpm and 102.43 pound-feet of torque at 3,240 rpm.
Compared to the stock, the Stage I version produced 9.39 more hp and 2.04 additional pound-feet of torque.
