Raw Power, Carbon Obsession
KTM built 350 of these, and not one of them is meant to blend in. The RR takes the Super Duke idea to its limit: carbon fiber bodywork, a lightweight exhaust, and the 1350 cc LC8 V-twin with CAMSHIFT making 190 hp and 107 lb-ft. WP PRO COMPONENT suspension is fully adjustable at both ends, the ergonomics move to fit the rider, and eight ride modes sit behind cornering ABS, traction control and wheelie control, with the quickshifter working both ways. Nothing in the Super Duke line is sharper than this.
It is a single-minded motorcycle and it does not pretend otherwise. The riding position is aggressive, the 33.0 in seat is high, and the whole bike assumes you ride hard and ride often. Set the suspension for your weight and it pays you back every session; leave it on the delivery settings and you are wasting the best part of what you bought. Who it suits is narrow by design: experienced riders chasing intensity on canyon roads and track days, not people covering interstate miles. Everybody else should look at something calmer in the range.

You notice the height first. At 33.0 in, the seat puts you over the front of the bike rather than behind it, and once the LC8 fires there is no mistaking what you are sitting on. A big 75° V-twin with a hard, uneven bark that gets louder and angrier the further you wind it out. It pulses, too. Not the numb hum of a four, but a real mechanical beat coming up through the pegs and the tank, telling you the engine is doing work. The carbon bodywork keeps the whole machine feeling small underneath you. The ergonomics adjust, so your contact points end up where your body wants them instead of where a compromise left them. At normal road speeds you are using a fraction of what is there, and the bike never lets you forget it.
None of this comes off a press kit. It is what I hear in paddocks, at club nights, in owner conversations, and in the messages riders send me directly, collected over years of asking the same questions. On the RR the chatter runs unusually consistent, and it splits cleanly between what riders love and what they put up with.
Riders consistently describe a bike that feels smaller and lighter underneath them than they expected, and one that changes direction the moment they ask. The engine comes up in nearly every conversation, talked about in terms of the shove rather than the numbers. Setup is the other constant: owners spend real time on the suspension and the rider aids, and they like how far both let them move the bike toward their own pace. A smaller group counts the rarity itself as part of the appeal.
The complaints are fewer and quieter. Wind is the one raised first, and how tiring the bike gets when the pace stays high for long. Some riders mention wrists and lower back after a long day, down to the stance and a firm seat. A few owners bring up parts, both what they cost and whether they will be there when needed.
Keyless ignition intermittent 'key out of range' warning
The dashboard occasionally displays 'key out of range' even when the key is nearby, requiring a restart or repositioning of the key.
Minor electronic glitches reported on 1390 platform
Owners note that while show-stopping issues are rare, minor electronics bugs can occur, such as sensor errors or glitchy ride mode switching.
Where this KTM 1390 Super Duke RR pulls ahead of — or falls behind — its rivals on the numbers, and the typical bike in its class on character.

Forget spec-sheet bragging. Here's who the 1390 Super Duke RR is actually built for.
This is your bike. Fully adjustable WP suspension, eight ride modes and lean clearance that outlasts most riders means you spend your sessions refining technique instead of fighting the setup.
Made for Barber Motorsports Park · WeatherTech Raceway Laguna Seca · Circuit of the Americas
Ideal once the road opens up, less so getting there. The crawl out of LA is the price you pay; after that, the low-end drive and the chassis make the whole day worth it.
Made for Angeles Crest Highway · Coronado Trail / US 191 · Highway 1 / Big Sur
Honest answer: it is more engine than those corners need. If precision is the goal, the adjustable chassis earns its keep on repeated tight turns, but you will only ever use a slice of the power.
Made for Back of the Dragon · Blue Ridge Parkway · Cherohala Skyway
