2020–2024 · Hyper Naked · A variant of the Streetfighter V4
Differences between the standard Streetfighter V4 and the S
208 Horses, No Bodywork
Strip the fairing off a superbike and you get this. The 1103 cc V4 spins to a 208 hp peak, but the figure that defines its character is 91 lb-ft and how early it arrives. Power builds from just off idle with an industrial, relentless shove, then keeps pulling all the way to a 175 mph top end. Ducati wrapped it in a full electronics package: cornering ABS, traction and wheelie control, ride modes, launch control. In its class this sits at the sharp performance end, a road-legal track weapon that happens to wear handlebars instead of clip-ons.
On the road it is more civil than the spec sheet suggests. Street mode softens the throttle enough to make city miles bearable, and the chassis stays composed rather than nervous when you lean on it. This is a bike for experienced, sport-focused riders who want superbike pace without bodywork, and who will actually use it on canyons or track days. The honest caveat is everyday reach. A 33.3 in seat, 29 mpg, and a 4.2 gal tank mean short legs between fills and a tall step over. It rewards commitment, not errands.

The Streetfighter V4 S (MY2020-S) builds on the standard Streetfighter V4: the upgraded hardware, the key spec changes and where its character shifts. The full ride, specs, scoring and verdict are all right here on this page.
Equipment the S adds vs the standard Streetfighter V4
Over the years I have listened to a lot of Streetfighter V4 owners: in the paddock, at club nights, and in the messages riders send me directly. Put all of that together and a clear pattern forms. Owners rave about how this bike handles, stops and pulls, and they are remarkably content with it. The complaints gather around daily life with it: heat, running costs and a short list of missing conveniences.
The most consistent praise goes to the handling. Riders describe precise turn-in, a stable front end and a balance that stays settled as the pace climbs, and nobody reports it shaking its head or wallowing. What surprises many is how forgiving it feels for a bike with superbike power. The brakes earn nearly the same approval, with owners singling out both the outright stopping power and the fine modulation at the lever. The electronics come up often too. Riders talk about cornering ABS, traction, wheelie and slide control that feel sensitively calibrated rather than intrusive, and ride modes that let the same bike move from town duty to full attack.
Owners describe the power as brutal yet surprisingly linear, and many regard this V4 as the high point of the engine type. A recurring observation is that its character is at its best above 7,000 rpm, and riders who take it on track report pace at the front of its class. Comfort is the unexpected talking point. Compared with the Panigale V4, owners find the upright bars and extra legroom far easier to live with, and taller riders say they fit well. Owners also speak well of the premium materials and finish. Overall satisfaction runs high, with reliability and ride quality named specifically.
Heat is the single most discussed issue. Owners locate much of it at the slits beside the seat, where the rear cylinder bank radiates onto calves and inner thighs once the air passes about 77°F (25°C). The rear bank shutting down at a standstill helps at long red lights, riders say, but does little in crawling stop-and-go. Throttle response is the next gripe. In Sport and especially Race mode, owners report a lag and then a surge in the first inch of travel, more noticeable with this upright posture than on the Panigale. Several say Sport mode with the Low power setting tames it on the street. Wind protection is essentially nonexistent, and above roughly 80 mph (130 km/h) riders call it physically tiring. Running costs draw steady comment, above all the desmo valve service every 15,000 miles (24,000 km), which owners describe as labor-heavy because pipework has to come off even on a naked bike. Some also point out what the price leaves out: no cruise control, no keyless, no USB port, and tire pressure monitoring only as an option. Shorter riders add that the seat is tall, with no factory low seat for this generation.
Forged alternator flywheel can break
The alternator flywheel (supplier Mitsuba) may have cracks in the forged blank. Under high stress the rotor can break, damage the generator housing and cause oil loss. Affects exclusively units produced July 3-30, 2020.
Structural failure of the rear axle
The rear axle of the single-sided swingarm can lose its structural integrity and break. Cause: insufficient machining tolerance combined with stress. 11 reported cases worldwide (none in the USA at time of recall). Affects all Ducati V4 models with single-sided swingarm (Panigale + Streetfighter).
Ducati Quick Shift (DQS) malfunction and limp mode
The quickshifter fails to reliably execute upshifts under hard acceleration (engine cut without gear change). False neutrals between 4th/5th and 5th/6th gear. DQS error message can trigger limp mode (rev limit at approx. 4,000 rpm). Causes: defective DQS sensor, gear position sensor or throttle position error. ECU reset (ignition off/on) can help. Aftermarket gearing changes worsen the problem.
Elevated oil consumption and oil ingress into the airbox
Some V4 engines exhibit elevated oil consumption. Oil blow-by into the airbox has been reported at low mileages (from approx. 4,000 mi (6,500 km)). Oil consumption varies by individual engine and oil used: racing oils (e.g. Motul 300V) tend to cause higher consumption than street oils. Correct measurement requires 2 hours of standing time for oil return. In severe cases: engine replacement under warranty documented (on V4R).
Fuel boils in tank at high temperatures
Tank sits above the engine and is additionally heated by the exhaust headers. At high ambient temperatures (especially on track) fuel can form vapor bubbles, leading to engine stumbling or stalling. Ducati introduced a thermally reflective tank insulation as an official retrofit solution from MY2024.
Oil or coolant leak at the water pump seal
The water pump seal can fail. Oil or coolant leaks from the weep hole (inspection bore in the V of the engine). In severe cases leaking coolant can wash out the pump shaft bearing. Ducati has performed multiple seal revisions. Cross-platform issue (also Panigale V4).
Heavy clutch action and clutch fade under heat
The clutch action is perceived as heavy in stop-and-go traffic. Under high thermal stress (traffic jams, track) clutch fade occurs. Some owners report that the clutch needs to be bled regularly. Aftermarket slave cylinders are offered as an improvement.
Extreme heat radiation to rider at low speeds
The aluminum frame head acts as a heat sink. At low speeds, the engine radiates intense heat onto the rider's thighs and calves. Reports of noticeable burns after short rides in city traffic. Problem known since Panigale V4. Rear cylinder bank deactivates at standstill for heat reduction. At higher speeds, cooling from airflow becomes sufficient.
Battery drains during extended storage
The lithium battery (V4 S) drains during extended storage. Possible causes: ECU continuing to run when switched off, immobilizer, ABS module, aftermarket electronics (GPS tracker, alarm systems). DDA (Ducati Diagnostics Adapter) draws current when permanently connected. Recommendation: battery tender during storage (charging connector pre-wired from factory).
Difficult cold start / multiple cranking attempts required
Engine does not start on first attempt; 2-3 cranking attempts or waiting time required. Causes: lithium battery loses cranking power below 55°F (13°C); tight tolerances of the V4 engine require high cranking current; ECU cold start learning cycle can reset. Fuel pump needs priming time (wait for relay click before cranking). Dealer statement: V4 engine needs approx. 3,100 mi (5,000 km) to break in.
Quickshifter (DQS) missed upshifts and Gear Position Sensor failure
Two related symptoms reported across MY2020–2024 units. (a) The DQS misses upshifts intermittently — most often 3→4 and 4→5 — and occasionally finds neutral on a missed shift. (b) The Gear Position Sensor (GPS, mounted on the engine case) can fail under heat exposure, requiring replacement and a Ducati Diagnostic System (DDS) relearn procedure. Downshift function intermittently fails when the GPS is degraded. Quickshifter problems are among the predominant issues reported by owners of MY2023 units. Service-bulletin DDS updates reportedly improve part-throttle quickshifter feel.
Twitchy / abrupt initial throttle pickup in Sport and Race ride modes
Sport mode (medium power, progressive ride-by-wire) and especially Race mode (full power, direct ride-by-wire) produce an abrupt initial throttle pickup — owners describe a small dead-band followed by a surge in the first inch of throttle travel. More noticeable on the Streetfighter than on the Panigale V4 because of the upright posture (rider's mass over the bars amplifies any abruptness). Common owner mitigation: select Sport-with-Low power mode for street, custom ECU flash (Woolich), or aftermarket exhaust + remap. Not a defect — a calibration trait.
Rear-cylinder heat radiating into rider's thigh and seat area
Heat from the rear cylinder bank radiates through slits beside the seat. Owners report calf and inner-thigh discomfort, and in extreme cases burns, in stop-and-go traffic and ambient temperatures above 77°F (25 °C). Some owners report symptoms after a 20-minute ride. Cylinder deactivation at standstill helps at sustained idle (long red lights) but not in slow-rolling stop-and-go. Mitigations cited in the community: aftermarket frame heat covers (Lieb-Speed), heat-shield tape under exhaust covers, full Akrapovič exhaust (better airflow).
Battery drain when DDA stick or tracker module is left connected during parking
The Ducati Data Analyser USB stick, when left plugged in, draws current during parking and drains the battery within 1–2 weeks of inactivity. Aftermarket trackers / alarm modules add to drain. Ducati issued an internal dealer-bulletin email instructing owners to remove the DDA when not riding. A trickle charger or a battery tender is required for storage longer than approx. one week with DDA installed.

Forget spec-sheet bragging. Here's who the Streetfighter V4 is actually built for.
On Angeles Crest and the westside passes it comes alive: light steering, brutal drive out of corners, composed when you lean on it. Just respect the low-speed heat and heavy clutch when traffic stacks up.
Made for Angeles Crest Highway · Coronado Trail / US 191 · Highway 1 / Big Sur
If your weekends are spent lapping a closed circuit, this is squarely your bike. The adjustable suspension and deep electronics let you build confidence session by session, and the V4 has the top end to reward a clean apex.
Made for WeatherTech Raceway Laguna Seca · Barber Motorsports Park · Circuit of the Americas
On the Dragon and Blue Ridge it turns quick and drives hard out of tight corners. The full power is more than these 30 mph bends need, so it rewards smoothness and restraint over chasing every straight.
Made for Tail of the Dragon · Back of the Dragon · Blue Ridge Parkway
If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.
Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Ducati Streetfighter V4. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
