The all-new Harley-Davidson Sportster S has been revealed overnight with the brand’s new Revolution Max V-twin engine at its heart.

The 1250cc Revolution Max V-twin initially found a home in the recently released H-D Pan America adventure bike. The engine features double-overhead cams, four-valves per cylinder and Variable Valve Timing (VVT), and in the Sportster S it makes a claimed 90kW at 7500rpm and 127Nm at 6000rpm.

The engine is a stressed member of the Sportster S’s chassis, which H-D says minimises overall weight. It tips the scales at 228kg wet.

Two huge exhaust pipes down the right-side off the Sportster S are said to be inspired by “the glory days of H-D flat-track racing”, but while these pay homage to Harley-Davidson’s rich history, this bike looks to the future, not the past.

Modern Sportster S features include rider-selectable Ride Modes including Sport, Road and Rain, or a custom mode that allows the rider to tune power delivery, engine braking, Cornering Enhanced Antilock Braking System (C-ABS) and Cornering Enhanced Traction Control System (C-TCS) settings.

A Bluetooth-equipped four-inch LCD screen displays digital gauges, indicators, ride modes, and turn-by-turn navigation with the Harley-Davidson app.

Up front the Sportster S runs a 43 mm USD fork with compression, rebound and spring preload adjustability, while there’s a mono shock rear-end with compression, rebound and hydraulic spring preload adjustability.

The braking package consists a radially mounted monoblock four-piston caliper at the front and a single piston stopper at the rear.

In Australia, the Sportster S will retail from $26,495 in Vivid Black, or $26,790 of you want it in Midnight Crimson or Stone Washed White Pearl.
