The Slingshot is manufactured by Polaris Industries, which claims that “It’s a three-wheeled motorcycle!” It has a tilt-adjustable steering wheel, side-by-side bucket seats, and does not lean. It has no roof, doors, or side windows and the whole interior is waterproof so it can be hosed down and drained out using drain holes in the floor. The standard Slingshot has two 17″ front wheels and a singular 18″ wheel in the rear of the vehicle, while the Slingshot SL and SL LE Edition have two 18″ forged aluminum front wheels with a 20″ rear wheel. All models have a double-wishbone front suspension with an anti-roll bar. An optional five-speed automatic transmission is set to become available by April 2018. A small windshield is an optional extra on the base model, and fitted as standard on the SL model. There is also an optional fiberglass wind and sun cover which Polaris calls a “Slingshade” that features inset polycarbonate windows and snaps right to the Slingshot’s tube frame, acting somewhat like a hardtop roof. The steering wheel, gear stick, and brake, clutch, and throttle pedals have a conventional automobile layout.
