Brough Superior Dagger S: What the New Sport Variant Really Changes

• In-house 997 cc V-twin producing 102 HP (75 kW) and 87 Nm, unchanged from the standard Dagger
• Sportier ergonomics courtesy of a lower, further-forward handlebar and a narrower body profile
• No official price has been announced; it is said to match the regular Dagger

French boutique manufacturer Brough Superior continues to expand its modern model range. With the Dagger S, the Toulouse-based company introduces a second variant of its carbon-bodied roadster, a machine that already ranks among the most technically elaborate production motorcycles on the market in its standard form. The S variant targets riders seeking a more focused, sportier riding experience, though it stops short of major changes to the engine or chassis.

What Sets the Brough Superior Dagger S Apart from the Standard Dagger?

The Dagger S adopts a sportier riding position along with minor aerodynamic and visual tweaks, while the engine, frame, and suspension remain unchanged. The handlebar now sits lower and further forward, shifting more weight over the front wheel and placing the rider in a flatter, more active posture.

The compact front fairing has also been revised. According to Brough Superior, the cutouts and overall shape of the fairing are more aggressive than on the original Dagger. A concrete difference can be read from the spec sheet: at 752.8 millimeters, the Dagger S is narrower than the standard version, which measures 782.5 millimeters. Length (2,168 millimeters), seat height (810 millimeters), and wheelbase (1,491 millimeters) remain identical.

How to Spot the Dagger S at a Glance

Visually, the Dagger S stays close to the familiar Dagger. The most prominent distinguishing features are a honeycomb pattern in the carbon on the tank top, additional fairing elements flanking the radiator, and the badging with the added S for Sport designation. Beyond these details, the bodywork is largely identical to the base model.

Like the standard Dagger, the S version wears a full carbon-fiber body including a carbon tank. Within the modern Brough lineup, the Dagger series marks a deliberate break from the brand’s classic retro influences. Instead of chrome-laden styling and tapered exhausts, the Dagger relies on clean, modern surfaces, a satin finish, and a prominently placed radiator.

How Much Power Does the Brough Superior Dagger S Produce?

The in-house 997 cc V-twin delivers 102 HP (75 kW) at 9,600 rpm and 87 Nm (64 lb-ft) at 7,300 rpm according to the manufacturer. The Dagger S thus carries over the standard version’s powertrain without modification.

The engine is a water-cooled 88-degree V-twin with double overhead camshafts and four valves per cylinder. Bore measures 94 millimeters and stroke 71.8 millimeters, with a compression ratio of 11:1. Fueling is handled by electronic fuel injection with a Synerject ECU and two 50-millimeter throttle bodies. Power reaches the rear wheel through a six-speed cassette-type gearbox and a hydraulically actuated multi-plate wet clutch with an APTC slipper function. The drivetrain is Euro 5 compliant.

Chassis and Brakes: The Fior Fork as a Brand Signature

The technical centerpiece of the chassis is the Fior-type front suspension characteristic of Brough Superior, a billet-machined aluminum assembly with two articulated triangular titanium struts. The system separates steering and suspension functions and serves as a visually and technically distinctive hallmark of the brand. The design traces back to engineer Claude Fior, whose principle BMW later adopted for the Duolever fork on its K-series models.

Front and rear suspension are adjustable for preload and rebound and offer 120 and 130 millimeters of travel, respectively. The frame is machined from titanium, supplemented by a titanium subframe. The steering head angle is listed at 22.8 degrees with 85.8 millimeters of trail. Braking is handled at the front by two 320-millimeter stainless steel discs with radially mounted four-piston calipers, and at the rear by a 230-millimeter disc with a two-piston caliper. The billet aluminum wheels in 17-inch format carry a 120/70 tire up front and a 200/55 at the rear. The manufacturer states the weight at 200 kilograms (roughly 441 lb) with a 50/50 distribution.

How Much Does the Brough Superior Dagger S Cost?

Brough Superior does not quote an official retail price, stating that it matches the regular Dagger. The manufacturer’s website notes that the price remains the same regardless of the ordering channel chosen.

For context, the brand’s sibling models provide a reference. The Lawrence Original was priced at around 66,900 euros (approximately 76,300 US dollars) at its launch, while the Lawrence Nefud came in at about 68,800 euros (roughly 78,400 US dollars). A Brough Superior thus occupies a price bracket far above mainstream production motorcycles. The Dagger S can be ordered through online pre-sales, directly at the Toulouse showroom, or through the brand’s retail partners.

The Dagger S Within the Brough Superior Model Range

The Dagger S joins the brand’s modern lineup, which alongside the Dagger also includes the Lawrence and the Nefud, setting itself apart from the classic heritage line built around the SS100. Brough Superior was founded in England in 1919 and relaunched in France from 2013 onward. Today the motorcycles are built in a boutique workshop in Toulouse, with limited production numbers and a strongly artisanal manufacturing process.

A technical link to the Aston Martin collaboration is provided by the radiator, which was derived from the jointly developed AMB 001. Within the current model year, the Dagger S is less a clean-sheet design than a more purposeful alignment of an existing model toward sporting dynamics.
