2021 Harley Davidson Forty-Eight Features

1200 cc Air-Cooled Evolution® Engine

An iconic V-Twin engine that is renowned for its massive low-end torque and soul-satisfying sound. Lightweight aluminum heads and cylinders improve air-cooling efficiency.

Fat Front Wheel

Custom rubber reminiscent of the lead-sled culture. You get a beefy front end with a tall, fat MT90 tire that gives the bike a dominating presence up front and provides a smooth ride and solid handling.

49mm Fork with Cartridge Dampening

The brawny 49mm front fork is accentuated by massive triple clamps and fork brace. We’ve also added cartridge damping technology to keep the handling crisp and confident, no matter how rough or winding the road ahead.

Emulsion Rear Shock with Screw Adjuster

Features an Emulsion rear shock with a screw pre-load adjuster that soaks up every bump the street throws your way, and easily adjusts to fit your riding style.

Split 9-Spoke Cast Aluminum Wheels

A set of black hardcore rims with added machined highlights to set off the design. They’re built of lightweight cast aluminium, so even with the plentitude of fat black rubber rolling underneath the ride feels light and nimble.

Foundation Brake System

An innovative, high-performing system that gives riders more confidence on the road and more power and predictability when you squeeze the brakes.

Iconic 2.1 Gallon Fuel Tank

A classic peanut fuel tank design that adds to the machine’s low, powerful bulldog look, showing off the solid mass of the engine and the rawboned style of the lean Sportster® frame.
