2020 Forty-Eight® 

Heavy-hitting style with fat tires and iconic peanut tank. Designed with its signature bulldog stance and 1200cc of corner cranking torque.


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 dampening technology to keep the handling crisp and confident, no matter how rough or winding the road ahead.


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 aluminum, so even with the plentitude of fat black rubber rolling underneath the ride feels light and nimble.


Foundation Brake System

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.
