Harley-Davidson Softail Night Train FXSTB (MY2008) vs Softail Fat Boy FLSTF (MY2008)

Roll out on the Harley-Davidson Softail Night Train FXSTB and it's all blacked-out paint, wrinkle-black covers and a bobbed fender. The Harley-Davidson Softail Fat Boy FLSTF rolls on fat tires and solid wheels, and it doesn't wander off a straight line. Its soft suspension soaks up the miles.

Slight edge: Softail Fat Boy FLSTF

What makes each one tick

Softail Night Train FXSTB

The Night Train's rigid-mounted Twin Cam 96B thumps out low-end grunt, and there's that unmistakable Harley bark in the pipes. Corner entry finds you stretched long between forward pegs and a narrow drag bar, out over a raked-out front end. That stretch doesn't stay kind over a long day. The six-speed hums at highway pace.

Softail Fat Boy FLSTF

The Fat Boy's Twin Cam 96B pulls deep and lazy from low revs, and it's happiest loafing down a boulevard. Every squeeze of the brake lever has 714 lb (324 kg) of low-slung cruiser to haul down. On Iron Mountain Road, the bar won't turn in without a deliberate push. Its chromed twin draws every look.

Comfortable long-distance riding

Not built for this

Hours in the saddle won't flatter either of these. They're happier on shorter runs.

Sporty riding on twisty roads

Not their thing

A string of bends won't flatter either of these. They're built around other priorities.

For running costs, you won't find daylight between them. Let the test ride settle it.
