$13,399 Austrian twin vs. $12,699 Japanese triple, and the canyon gets the final say
Summary: Episode 2 of our Head 2 Head series pits the 2026 KTM 990 Duke R ($13,399) against the 2026 Yamaha MT-09 SP ($12,699). Red Bull freestyle street rider Aaron Colton and Adam Waheed run both bikes on matching Bridgestone RS12 tires and EBC pads through canyons, a drag race, a wheelie test and a cornering session.
The specs can wait. That’s the whole plot of the teaser for Episode 2 of Head 2 Head, our video series where two street bikes go toe-to-toe and the road settles the argument. One of us starts reciting engine figures, the other cuts him off, and the conversation ends with the most honest product briefing in motorcycling: “Turn and burn.”
This round brings two of the meanest middleweight naked bikes on sale in America: the 2026 KTM 990 Duke R and the 2026 Yamaha MT-09 SP. One is a 947cc parallel twin from Austria that KTM calls “The Punisher.” The other is an 890cc crossplane triple from Japan that Yamaha bills as the “Master of Darkness.” Neither nickname suggests a relaxing Sunday ride, and that’s exactly why we picked them.
What’s in Head 2 Head Episode 2
Head 2 Head launched with a middleweight sportbike fight between the Yamaha YZF-R7 and Suzuki GSX-8R (catch the Head 2 Head Series Premiere if you missed it). For Episode 2, Aaron Colton, Red Bull’s freestyle street rider, and Adam Waheed take the naked bikes into the mountain canyons instead of starting with a spec-sheet lecture.
According to the episode’s official description, the full video covers:
- A series intro and a quick bike overview and spec comparison
- Street and canyon ride impressions
- A drag race between the KTM 990 Duke R and Yamaha MT-09 SP
- A wheelie test, because of course there’s a wheelie test when Aaron is involved
- A cornering and tire performance segment
- Final thoughts and the winner announcement
We’re not spoiling the winner here. Half the fun is watching the comments section argue about it first.
Leveling the Playing Field: Same Tires, Same Pads
Out of the crate, these two bikes don’t wear the same rubber. KTM fits the 990 Duke R with Michelin Power Cup 2 tires, while Yamaha lists Bridgestone Battlax Hypersport S23 tires on the MT-09 SP. Great for showrooms, bad for a fair fight.
So for Head 2 Head, both bikes were fitted with the same Bridgestone Battlax Racing Street RS12 tires and the same EBC Double-H EPFA sintered brake pads. That way, the differences come down to the motorcycles (and, fine, a little to the riders).
2026 KTM 990 Duke R: The Punisher
KTM built the 990 Duke R on its 990 Duke platform and turned up just about every dial. The engine stays at 947cc, and KTM says the LC8c parallel twin makes more horsepower and torque thanks to improved mapping. The U.S. technical specifications list 127.84 PS and 103 Nm (about 126 hp and 76 lb-ft), while KTM’s model page rounds the power figure up to 130 PS (about 128 hp). Either way, it’s a big number for a bike that weighs 419 pounds fully fueled, according to KTM.
The chassis gets the serious upgrades. Up front is a 48mm WP APEX Open Cartridge upside-down fork that KTM says is 34% stiffer than before, clamped in new forged aluminum triple clamps and offering 5.63 inches of travel. Out back, a new WP APEX shock delivers 5.51 inches of travel. Both ends are adjustable: 30 clicks of compression and rebound plus preload at the fork, and high- and low-speed compression, rebound and preload at the shock. The frame is a chromium-molybdenum steel unit that uses the engine as a stressed member, paired with an aluminum subframe.
The R also sits taller. Seat height rises 15mm to 840mm (33.1 inches, which KTM rounds to 33 inches) over the standard 990 Duke, with a matching 15mm gain in ground clearance, and the aluminum footpegs move back. It’s homologated to carry a passenger, but KTM sells it as a single-seater with pillion parts available separately. Translation: your buddy can come along, but the bike would rather he didn’t.
Electronics include Rain, Street, Sport and a new Custom ride mode as standard, with additional Track and Custom performance configurations sold as technical accessories. KTM lets owners try everything in demo mode for the first 1,500 km (about 932 miles), which is a clever way of making you miss features you didn’t pay for. Brakes are dual 320mm (12.6-inch) front discs with radially mounted four-piston calipers and a 240mm (9.4-inch) rear disc. The 990 Duke R is designed, developed and produced in Austria and carries a $13,399 MSRP plus $800 freight.

2026 Yamaha MT-09 SP: Master of Darkness
Yamaha’s answer is the MT-09 SP, the premium version of its CP3-powered hyper naked. The 890cc liquid-cooled, DOHC inline triple is tuned for sound on purpose. Yamaha adds Acoustic Amplifier Grilles on top of the fuel tank to pipe induction noise toward the rider. Yamaha doesn’t publish a horsepower figure on its U.S. spec sheet, so we won’t invent one.
The SP-exclusive hardware is where the extra money goes. A 41mm DLC-coated KYB inverted fork is fully adjustable for preload, rebound and high- and low-speed compression, with 5.1 inches of travel. An Öhlins rear shock is adjustable for preload, compression and rebound, adds a remote preload adjuster and provides 4.6 inches of travel. Brembo Stylema monoblock calipers grab dual 298mm (11.7-inch) front discs through a Brembo radial master cylinder.
Electronics run through a six-axis IMU that Yamaha says matches the base performance of the unit in the YZF-R1 superbike. It powers a four-mode Traction Control System, Slide Control System, front-wheel Lift Control System and two-mode Brake Control System. You also get an Advanced Quick Shift System for clutchless up- and downshifts, an assist and slipper clutch, cruise control, a five-inch color TFT with smartphone connectivity via the Y-Connect app, and a Smart Key system. New for 2026, Yamaha includes two Smart Keys.
The MT-09 SP weighs 428 pounds wet, carries 3.7 gallons of fuel, and Yamaha estimates 48 mpg. Seat height is 32.5 inches. Pricing is $12,699 MSRP plus a $700 destination charge.

By the Numbers: Twin vs. Triple
On paper, this fight is closer than the nicknames suggest. Here’s what the official numbers say:
- Price: The KTM costs $700 more at MSRP ($13,399 vs. $12,699). Add destination and freight, and the gap grows to $800 ($14,199 vs. $13,399). Fun fact: the Yamaha’s total base price lands on exactly the KTM’s sticker price before freight.
- Weight: The KTM claims 419 pounds fully fueled, and the Yamaha claims 428 pounds wet, so the Duke R is about 9 pounds lighter on paper.
- Engine: 947cc and two cylinders for KTM vs. 890cc and three cylinders for Yamaha.
- Seat height: The KTM sits 0.6 inch taller at 33.1 inches vs. 32.5 inches.
Numbers only tell you so much, which is why the teaser told the spec-sheet guy to zip it.
