Harley-Davidson Sportster S: Revolution Max engine, power and what to check
Harley-Davidson Sportster S — the 2021 model introduced with a modern liquid-cooled Revolution Max engine. We look at what sets it apart from previous Sportsters, its tech and what to check when buying used.
Sportster S in brief
Sportster S — the new generation of Harley-Davidson motorcycle that has taken the Sportster name but features entirely new technology. It combines classic Sportster style with modern solutions: liquid cooling, electronic rider aids and a digital display.
Despite the familiar name, this model has little in common with the earlier air-cooled Sportster 883 and 1200 — it's a different beast with a different ride.
What sets it apart from older Sportsters
Older Sportsters had air-cooled Evolution engines and basic electronics. The Sportster S has the Revolution Max 1250T engine — a liquid-cooled V-twin with variable valve timing, making it more powerful and modern.
On the electronics front, there are riding modes, traction control, cornering ABS and a TFT display. This makes the ride safer and more adaptable to different conditions.
Engine and transmission
The engine is a 1.25-litre 60° V-twin with around 120 hp. It pulls strongly across the rev range, making the Sportster S one of the more dynamic Harley-Davidson models.
The transmission is a six-speed manual, with power delivered via a belt. The belt doesn't require oil but does need periodic checks.
What to check when buying a used Sportster S
As this is a fairly new model, most examples are still quite fresh, but it's essential to check the service history and whether manufacturer recalls have been carried out (if any). Ask the seller to show you the invoices.
Inspect the tyres, brakes, throttle, electronic modes, and screen operation, as well as any signs of crashes. Test that all modes work and there are no error messages.
