Built for the track, it's faster than the V4 S expected.Ducati has expanded its Streetfighter V4 range with the addition of a Sport Production “SP” model ahead of the MY2022.Race livery and wind tunnel-tested bodywork complete the package.Under the skin, the Desmosedici Stradale acts like a beating heart, with over 200 ponies on standby.Top rack suspension and steering control electronics complete the package and overall it sits at the top of the Street Fighter lineup.It produces 208 horsepower and 90.7 pound-feet of torque.Yes, it got soaked on a bike that weighs 432 pounds, so you know right away that it's a fun ride.As the clever name suggests, the engine layout is a V4 configuration, but it works like a V-twin thanks to the dual-pulse firing sequence.Operating with an 81mm bore and short stroke of 53.5mm, the large super square mill has a total displacement of 1,103cc and a compression ratio of 14 to 1.Whether or not you're using it as race fuel on the track, you need to meet your engine's octane needs one way or another.The Ducati tradition of using the Desmodromic camshaft is still alive at this Desmosedici Stradale factory, so there are no valve springs.Instead, a pull cam provides positive trigger closure.This precaution eliminates the chance that valve harmonic fluctuations will become a factor because it is prevented from forming in the first place.Each combustion chamber has four triggers to allow this engine to breathe freely, and it should, as it will reach an impressive 12,750 rpm.The dry slip clutch is hydraulically actuated with an automatic bleeder for consistent performance, and the six-speed transmission features Ducati's Quick Shift.DQS allows you to enter and exit the track without touching the clutch.There's a six-axis inertial measurement unit that informs other systems, so anything that can be angle-sensitive is angle-sensitive.The engine electronics work in conjunction with the traction/skid/wheel/engine brake control systems, most of which are also “EVO 2” functions for a nearly unrivaled electronics package.A set of Riding Modes monitors everything and allows for quick real-time personality changes using the switch hub on the handlebar switch housing.A set of Riding Modes monitors everything and allows for quick real-time personality changes using the switch hub on the handlebar switch housing.A chain-type final drive sends power to the rear wheels, and the Streetfighter V4 SP's overall gear ratio reaches a top speed of 180 mph.On the surface, the Streetfighter V4 SP is technically a cosmetic package added to the base model Streetfighter V4, but the improvements are cut to the core.One way or another, these changes expand the performance envelope and reduce overall weight, improving the power-to-weight ratio.It starts with a strong and light carbon fiber front bumper, reduced to the limit of functionality.Less air contact means less drag, and of course the low unsprung weight also helps with suspension response.Dual LED headlights separate the night with DRL eyebrows (also LEDs), increasing your visibility to the rest of the world during the day.A digital instrument display handles all relevant metrics from a location on top of the headlight housing, as well as steering control and safety components.At the entrance of the bucket, the limited body has a strong leading edge that quickly dissipates to the rear.This not only works as a fairing for the cooler, but also supports the dual wing blades on both sides.Blades create extra downforce on the front wheel at high speeds to keep the nose down and the front rim secure.They feature downward-facing tips to prevent drag-inducing vortices from forming on the wingtips to protect overall gains made elsewhere.The 4.23 gallon tank has a wide flange before it drops hard to accommodate the tight seat and frame.This makes it easier to lower your feet, leaving room and knee traction for British body movements.Still, the seat sits 33.3 inches above the deck, so shorter riders will have the added benefit of a slimmer waist.A coccyx pad helps support the rider's rear end, while an aerodynamic spoiler covers the rest of the rear with stylized taillights.Dual LED light bars double as turn signals, and a swingarm-mounted clamp completes the gearing at the rear.Ducati has taken the thrust engine concept to the nth level in the Streetfighter V4 SP with a bolt-on aluminum front frame section.The 24.5-degree incline and 4-inch trail let you dive deep into agile territory.The Öhlins steering damper absorbs the effects of the rebound you get when you start to lift the front wheel a little.At the rear, a swingarm on one side pivots to the rear wheel and keeps the weight unsprung through its reduced construction.Öhlins supplied the suspension with a set of 43mm NIX30 forks and a TTX36 shock.Both ends are fully adjustable, but the real selling point here is the Öhlins Smart EC 2.0 system, which provides event-based active adjustments for a superior riding experience.The frenzy continues on the brakes, overseen by Bosch Cornering ABS.Dual four-piston calipers bite into the massive 330mm front discs, providing ample leverage, while at the rear, two-piston anchors and 245mm discs handle the problem.A set of lightweight, five-spoke carbon fiber rims complete the 17-inch-diameter rolling chassis, lined with Pirelli Diablo Rosso Corsa II rims, 120/70 taller than 200/60.Naturally, the rubber rolls at a “Z” speed rating and can actually handle higher speeds than the Streetfighter V4 SP can deliver, so even at top speed you're within the tire's performance envelope.The Ducati Streetfighter V4 SP 2022 costs US$ 35,500 (R$ 190,773.45 Brazilian Real).It comes in “Winter Test” paint, red finish and brushed aluminum finish.There's no doubt that Streetfighter V4 SP is a tough act to follow.KTM in Italy's northern neighbor Austria may have an answer with its Super Duke R EVO.As for looks, Ducati won the contest, especially considering KTM's perhaps too bold bodywork and extreme angular appearance.To that end, KTM's V-twin launches 180 ponies, just short of the Ducati's raw power.The higher torque output of 103 lb-ft makes up for some of that, so in the end there's a trade-off.Electronics often have the same minimal advantage as Duc's impressive kit.Electronically controlled suspension is another constant that makes the Duke truly a worthy opponent.Unfortunately for Ducati, things quickly went downhill to the cashier.Compared to the Super Duke's $19,599 sticker, the KTM is in an enviable position, unless you don't like orange.
