Orange Attack Finally Faired
KTM's parallel twin sits in a steel trellis frame and makes 130 hp from 947 cc, with 76 lb-ft underneath it that arrives early enough to matter on a real road. This is a full-fairing sport bike built the way KTM builds things: front-end first, aggressive, no interest in smoothing the edges off. The chassis is the headline. WP APEX fully-adjustable suspension at both ends, cornering ABS, traction control, ride modes and KTM Ride-by-Wire engine maps give it the electronic backbone the class demands. Lean clearance is genuinely enormous, and high-speed stability holds up when the pace climbs.
Rolling on 120/70-17 and 180/55-17 rubber at 434 lb wet, it changes direction with intent and keeps feeding you information about what the front tire is doing. That feedback is the reason the bike works: you know where you stand, so you commit. It's for riders who want a sportbike that rewards precision rather than one that flatters bad inputs. The honest caveat is the 33.3-inch seat and the riding position that comes with it. This is a committed sport machine, and a full day on it asks something of you. There's serious aftermarket support if you want to tune it further.

The first thing you notice is how narrow it feels between your knees. The parallel twin gives you a hard, flat pulse through the pegs at low revs that smooths out as it spins up, and the sound has that dry, mechanical edge rather than a screaming inline howl. You sit in it, not on it. Wrists take load, the tank meets your forearms where you want it, and the reach forward is real but not punishing at road pace. Your hands get a constant stream of what's happening at the contact patch, which is what makes the thing addictive. The 4.4-gallon tank and 58.3-inch wheelbase give it a proper big-bike footprint underneath a compact riding position, and at highway speed it sits still and holds its line without asking for corrections.
None of this comes from my own laps. It's the residue of years spent listening to riders: pit-lane conversation, owners talking shop in a parking lot after a ride, club nights, and the notes that land in my inbox. What comes back on the 990 RC R points in one direction most of the time, with a short list of doubts attached.
Owners keep circling back to the chassis. They describe a bike that stays settled underneath them and leaves room to push harder, on the road and at trackdays. The engine sits close behind: riders talk about a bottom-end punch with a motocross flavor that turns in-gear passes into a non-event and keeps things lively at everyday speeds. The brakes draw steady credit for power and feel. Smaller mentions: clip-on and peg adjustment for setting the position sporty or relaxed, and dash menus people find easy to work while moving.
Taller owners, roughly six feet and up, say the cockpit closes in and their legs run out of room once the ride goes long. Older questions about LC8c camshafts and oil consumption still circulate, usually with the owner's own caveat that KTM has worked through much of that list. The quickshifter, an option here rather than standard fitment, gets called notchy when new, settling after adjustment or some break-in.
OEM tire cracking
Some early units exhibited cracking on the Michelin Power Cup 2 tires, particularly in cold conditions, raising safety concerns.
Occasional transmission slip (4th to 3rd gear)
One test ride reported the bike slipping out of gear when downshifting from 4th to 3rd, which could disrupt corner entry. The root cause is unknown and may be an isolated incident.

Forget spec-sheet bragging. Here's who the 990 RC R is actually built for.
This is exactly the tool for Angeles Crest. The feedback and lean clearance let you build pace corner by corner, and it's light enough to change direction between blind crests without wearing you out.

A genuine trackday bike with adjustable WP suspension and cornering ABS out of the box. Set it up properly and it rewards precise braking and clean apexes rather than brute horsepower.
Made for Barber Motorsports Park · WeatherTech Raceway Laguna Seca · Circuit of the Americas
On the Dragon and Cherohala, this bike is about line accuracy, not speed. The front end tells you everything, so you can work on technique instead of guessing what the tire is doing.
