The popular Fat Boy gets new ergos, lowered
suspension, and the blacked-out treatment in this new version. It starts with
front and rear suspension that has been lowered by 1.15-inches. This dropped the
seat height to 24.25 inches, the lowest of any stock Harley. To match its new
low-riding seat height, the seat has a narrower cut as H-D looks to give the
2010 Fat Boy Lo more of an ‘in the bike’ feel.
Its dark side is represented by its gloss black finish on its triple clamp
covers and nacelle, headlight bucket, air cleaner cover trim ring, rear fender
supports, and floorboards. The frame, swingarm, front shock covers, oil tank,
and air cleaner cover all have a denim black finish. Its Twin Cam 96B engine has
black powdercoating, and the Bullet Hole Disc 17-inch cast aluminum wheels have
black centers and machined outer rims.
Though not officially one of Harley’s Dark Customs that targets younger riders,
the blacked-out treatment on the ’10 Fat Boy Lo follows in that vein. Its low
seat height and narrower handlebar could be a direct appeal to women riders as
well.

Key Features
Darker and lower, the Fat Boy® Lo retains the
bold presence of the Fat Boy® while offering a fresh interpretation of the
motorcycle that still defines the segment. A re-shaped seat and lowered
suspension combine to produce the lowest seat height of any Harley-Davidson®
model, just 24.25 inches.
The Softail® rear suspension mimics the clean lines of a vintage hardtail frame
but offers the comfort of a modern suspension that is hidden under the chassis.
The rigid powertrain allows tight packaging of the engine and frame and creates
a solid connection between the rider and the power that moves the motorcycle.
• Rigid-mounted, counter-balanced Twin Cam 96B™ V-Twin engine with Electronic
Sequential Port Fuel Injection (ESPFI)
• 6-Speed Cruise Drive® Transmission
• Horseshoe oil tank
• Five-gallon fuel tank
• Optional Harley-Davidson® Smart Security System with hands-free security fob
