The Fat Bob arrived for 2008 as a new member of the rubber-mount Dyna family, built to look heavier and more aggressive than its siblings. It paired the fuel-injected Twin Cam 96 and six-speed Cruise Drive gearbox with fat tyres on 16-inch slotted cast wheels at both ends, twin headlamps, a drag-style bar and a Tommy Gun 2-1-2 exhaust. Braided stainless brake lines were new across the 2008 Dyna range.
