We’ve gathered data on power, torque, and top-speed specifications primarily from manufacturer-provided information wherever available. In cases where such data was not readily accessible, we’ve relied on a variety of hands-on reviews of the motorcycles as our information source.

It’s worth noting that many motorcycle manufacturers, like KTM, frequently employ the same engines across multiple models in their lineup.

For instance, the Super Duke R Evo shares a common powerplant with the Super Duke R, Super Duke GT, and the Super Duke Adventure R and S variants. These models exhibit quite similar performance figures due to their shared engine.

Similarly, KTM’s LC8c engine can be found under the hood (or rather, fuel tank) of the 890 Duke R, RC 8C, 890 Adventure, and Adventure R models. However, what makes this particularly intriguing is that the 889cc LC8c engine finds its way into these diverse models, but the power outputs vary significantly. This variation is primarily attributed to differing tuning configurations and the distinct chassis designs in which the engine is integrated.

Now, let’s delve deeper into the top five fastest KTM motorcycles.

1290 Super Duke R Evo

The pinnacle of the Super Duke lineup, the Super Duke R Evo, truly embodies the essence of a ferocious powerhouse.

Under its hood lies a 1301cc V-Twin engine, an untamed beast brimming with unbridled potency. In its latest iteration, this engine has undergone a transformation, shedding weight through slimmer casings and enhancing oil delivery via aluminum oil lines.

With an astonishing top speed of 186 mph, the Super Duke R Evo promises an exhilarating journey. Boasting 180 horsepower and a torque output of 140 Nm, it bestows an abundant reservoir of power, generously accessible all the way to the redline.

To harness this monumental power, KTM has engineered an exceptionally robust frame, boasting three times the stiffness of its predecessor in the latest model. This lightweight frame seamlessly integrates with a composite subframe and swingarm, further reducing weight.

The inclusion of WP semi-active technology (SAT) suspension offers an extensive array of adjustability options, catering to both track and street preferences. Up front, the electronically adjustable WP Apex forks provide precise feedback and a tactile connection, enhancing rider confidence and control.

The Super Duke R Evo offers versatility in its riding experience. Embrace its upright riding position and street-oriented ergonomics for a comfortable urban cruise, or tap into its true supersport spirit—minus the fairings.

Key Specifications:

• Engine: 1301cc, LC8, V-Twin;
• Seat Height: 32.8 inches;
• Curb Weight: 466 pounds;
• Current MSRP: $20,399.

RC 8C

The RC 8C emerges as a thrilling creation from KTM’s recent production, exemplifying the brand’s commitment to delivering excitement on the track. Remarkably, this track-focused marvel was strictly limited to a mere 200 units, all of which were swiftly claimed by eager enthusiasts even before they graced dealership floors.

Every facet of the RC 8C exudes excellence, featuring race-spec components that render it race-ready right off the factory line. KTM has thoughtfully ensured that virtually every aspect is adjustable, accommodating riders of diverse sizes and preferences without compromise.

Armed with 132 horsepower and an estimated top speed reaching 174 mph, the RC 8C stands poised to wage a formidable battle on the track, chasing down lap records with unrelenting determination.

The motorcycle comes equipped with a 5-inch TFT display, seamlessly integrated with the AIM Race Studio, offering comprehensive data-logging capabilities. It diligently records essential metrics such as track speed, lap times, and engine data, providing invaluable insights for post-ride analysis.

The RC 8C’s aerodynamics are unrivaled, featuring lightweight yet robust carbon Kevlar-clad fairings that effortlessly slice through the air, while strategically positioned winglets generate additional downforce and stability.

Beyond its premium components and cutting-edge technology, the RC 8C boasts a striking visual presence. Its aggressive, mean-spirited design underscores its identity as a serious, no-nonsense racing machine.

Key Specifications:

• Engine: 889cc, LC8c, parallel twin;
• Seat Height: 32.2 inches;
• Dry Weight: 308 pounds;
• Current MSRP: To Be Confirmed.

890 Duke R

KTM’s 890 Duke R takes the foundation laid by the 790 Duke and elevates it to the next level of performance.

In the realm of middleweight naked bikes, the 890 Duke R is a standout, boasting an abundance of power and torque that injects vigor whether you’re navigating winding back roads or unleashing its potential on the racetrack.

Its parallel-twin engine delivers a robust 115 horsepower and propels the bike to a top speed of approximately 150 mph, making it abundantly clear that this motorcycle is more than sufficient for any street riding experience. Riding the 890 Duke R may leave you questioning the need for anything larger.

In terms of aesthetics, the 890 Duke R shares some design cues with its larger sibling, the 1290 Super Duke, featuring aggressive angles, sharp lines, and eye-catching accents. However, the 890 exhibits a more compact, streamlined profile, shedding unnecessary bulk.

Seated in an upright posture with generously wide handlebars and neutral footpegs, riders enjoy maximum control over the bike’s maneuvers. The fully adjustable WP suspension, both front and rear, can be finely tuned to accommodate varying road conditions and rider preferences.

Thanks to its lightweight chassis, the 890 Duke R is exceptionally agile, delivering precise handling characteristics that shine whether navigating bustling city streets or embracing the freedom of open roads.

With features like cornering ABS and Supermoto mode, the 890 Duke R eagerly invites riders to push its limits, encouraging the inner hooligan in all of us.

Key Specifications:

• Engine: 889cc, LC8c, parallel twin;
• Seat Height: 32.8 inches;
• Curb Weight: 405 pounds;
• Current MSRP: $12,949.

790 Duke

Despite the arrival of the 890 Duke in the Duke lineup, the 790 Duke maintains its relevance and purpose. In fact, I firmly challenge the notion that the 790 Duke has become obsolete, as it continues to excel as an outstanding, nimble, lightweight, swift, and sporty naked bike with much to offer.

Within its class, the 790 Duke features the most compact engine, nestled within a remarkably lightweight frame. This combination results in one of the finest handling and most agile setups presently available in the market.

Every aspect of the 790 Duke exudes an aura of agility and speed. Its appearance suggests an eagerness to conquer the road, with a design that trims away any superfluous elements, leaving only the essential core on full display.

The electronics package is truly impressive, featuring a comprehensive array of features, including Track Mode, Traction Control, Anti-Wheelie Mode, Launch Control, and three distinct throttle modes.

If you seek a middleweight street bike that can effortlessly adapt to a variety of riding scenarios while providing access to 103 horsepower and 86 Nm of torque, then the 790 Duke might be your ideal choice. With a top speed of 140 mph, it further solidifies its prowess in the middleweight street bike category.

Key Specifications:

• Engine: 799cc, LC8c, parallel twin;
• Seat Height: 32.4 inches;
• Curb Weight: 414 pounds;
• Current MSRP: $9,199.

890 Adventure R

Sharing the same engine as the 890 Duke, it’s no surprise that the 890 Adventure R closely follows suit in terms of impressive performance metrics.

However, the Adventure R’s engine undergoes a distinct tuning approach to prioritize ample low and mid-range power—a crucial characteristic for conquering off-road terrains. This tuning shift does result in a compromise on top-end power, resulting in a slightly lower top speed of 130 mph.

The 890 Adventure R emerges as a compelling choice for riders who prefer not to opt for the larger and notably heavier 1290 Adventure, which, for some, can be more challenging to handle.

With an extended wheelbase, the bike offers maximum stability, while the meticulously sculpted bodywork allows riders to achieve optimal movement when navigating challenging off-road landscapes.

Versatility is the name of the game with adjustable suspension both front and rear, enabling riders to fine-tune their ride for an optimal experience—whether they’re traversing the smooth tarmac or venturing onto rugged dirt trails.

KTM has further equipped the 890 Adventure R with a wealth of rider-centric technology, including Off-Road ABS, various rider modes (including Rally and Off-Road Mode), Cruise Control, and seamless Smartphone Connectivity.

Key Specifications:

• Engine: 889cc, LC8c, parallel twin;
• Seat Height: 34.6 inches;
• Curb Weight: 464 pounds;
• Current MSRP: $15,199.

KTM’s Other Noteworthy Motorcycles

Speed and KTM are inextricably intertwined, extending far beyond the brand’s renowned Supersports, Supermotos, and into the realm of MX and Enduro motorcycles. KTM’s penchant for producing high-performance machines is deeply embedded in its DNA.

Smaller Displacement KTMs

KTM excels notably in the realm of smaller-displacement motorcycles, making its mark in this category.

KTM stands as the frontrunner in the 300/400cc market segment. For an extended period, the 125 Duke reigned supreme as the fastest 125cc motorcycle internationally, relinquishing its title only recently to the MT-125.

The RC 390 commands attention with a top speed of 112 mph, delivering explosive acceleration right from the starting line. Similarly, the 390 Duke exhibits commendable performance, though the RC’s fairings optimize aerodynamics for a superior top speed.

The 200 Duke is no slouch either, quick off the mark with a top speed of 87 mph.

Off-Road Dominance by KTM

While our focus has centered on road and track motorcycles in our list of the fastest KTMs, it’s worth noting that KTM also produces some of the most rapid off-road machines available in the market.

KTM’s racing prowess extends well beyond the confines of MotoGP, with their riders consistently gracing podiums in MX, Enduro, and Rally competitions. Their ascent to victory is facilitated by no means other than swift engines encased within premium frames.

Here are a few examples of speedy KTM dirt bikes:

• KTM 450 SX-F: Achieving a top speed of 123 mph;
• The more compact 350 SX-F: Capable of hitting a top speed of 98 mph.

KTM’s Speediest Machine Ever

The 1290 Super Duke R Evo has secured its place as the reigning speed champion in the KTM lineup, representing the epitome of KTM’s pursuit of velocity.

This extraordinary motorcycle boasts an eye-watering top speed of 186 mph, propelled by an astounding 180 horsepower and a robust torque output of 140 Nm. Its acceleration is equally jaw-dropping, clocking a remarkable 0–60 mph time in just 3.1 seconds, though some argue it can break the 3-second barrier.

While undeniably the ultimate street bike, the Super Duke R Evo also defies convention by serving as a formidable choice for those who crave the thrill of the track. Its versatility extends beyond the confines of everyday roads, making it a solid option for riders seeking adrenaline-pumping experiences on the racetrack.
