2021 Ducati Streetfighter V4 S Overview
For 2021, Ducati offers the Streetfighter V4 S as a naked bike motorcycle with 1103 cc on tap. The 2021 Ducati Streetfighter V4 S is built around a Four stroke, Desmosedici Stradale 90° V4, rearward-rotating crankshaft, 4 Desmodromically actuated valves per cylinder engine, a compression ratio of 14.0:1. Out on the road, the Streetfighter V4 S delivers 208 hp @ 12750 rpm of peak power and 123 Nm @ 11000 rpm of torque. In everyday use, the 2021 Streetfighter V4 S tips the scales at 199 kg, carries a 16-litre fuel tank, offers a seat height of 845 mm and spans a 1488 mm wheelbase. That's roughly 9.5 kg lighter than the average naked bike motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2021 Ducati Streetfighter V4 S spec sheet below.
2021 Streetfighter V4 S - Pros & Cons
Strengths
-
⚡
Strong power output: Peak output on the Streetfighter V4 S is 208 hp @ 12750 rpm and 123 Nm @ 11000 rpm of torque - strong numbers for what it is.
-
🔧
Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
Considerations
-
📏
Tall seat height: A 845 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
-
⚙️
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.
Wear Points & Servicing Notes
Cooling system servicing
With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.
Fuelling & injector care
Fuelling on the Streetfighter V4 S comes from fuel injectionsystem. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.
Brake disc and pad wear
2 x 330 mm semi-floating discs, radially mounted Brembo Monobloc StylemaØ (M4.30) 4-piston callipers with Bosch Cornering ABS EVO up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.
Suspension condition on used examples
Suspension duties are handled by Öhlins NIX30 43 mm fully adjustable fork with TiN treatment. Electronic compression and rebound damping adjustment with Öhlins Smart EC 2 event-based mode up front and Fully adjustable Ohlins TTX36 unit. Electronic compression and rebound damping adjustment with Öhlins Smart EC 2 event-based mode. Aluminium single-sided swingarm at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.
Final drive maintenance
Chain final drive on the Streetfighter V4 S means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.
Frame & chassis check
The Aluminum alloy "Front Frame" chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
Streetfighter V4 S - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2021 Ducati Streetfighter V4 S should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept Streetfighter V4 S settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for a Streetfighter V4 S's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.
Fuel system care
Injector systems like the Streetfighter V4 S's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
