2021 Harley-Davidson Softail Slim Cruisers Review Price Specs

The new 2021 Harley-Davidson Softail Slim Cruisers is among those motorcycles known for the classic appearance of spoked wheels, floorboards, and chopped fenders on the Softail Slim. It is about 35 pounds lighter with a greater lean angle than Slim models from just a couple of years ago. The motorcycle comes with the power and soul-satisfying sound of the Milwaukee-Eight 107 V-Twin engine.

The new stripped-down and low-slung bobber brings old-school styling into the modern era; black steel lacked wheels, Hollywood handlebar, and tuck-and-roll seat cover and bobbed fenders come standard in it. An authentic heritage meets the latest technology for power, styling and unadulterated riding experience around town or along country roads. The essential stripped-down and low-slung bobber gives plenty of fun rides.
