One owner, bought here new! The 2020 Harley-Davidson Street Glide is one of Harley’s most venerable touring motorcycles. The bike is highway-ready, but it’s also happy to cruise the boulevards and city streets. It’s a bit of a stripped-down hot rod bagger. The Street Glide has the Milwaukee-Eight 107 engine. It’s an air-cooled V-twin that has a displacement of 1,753cc. The 107 engine is mated to a six-speed manual transmission and it makes 111 lb-ft of torque. The Street Glide is the kind of bike you get if you love the Harley-Davidson brand. It’s a comfortable cruiser that fully embodies the HD brand ethos.
