Ktm Superduke 990
The Ktm Superduke 990 has a top speed of 220 km/h, produces 115 hp and weighs 189 kg. Motoryk rates it 8/10.
The KTM 990 Super Duke was introduced in 2005 as a naked/streetfighter motorcycle built around KTM's LC8 V-twin engine, which had proven itself in the adventure touring segment. It quickly earned a reputation as an aggressive, raw, and visceral street machine, often dubbed 'The Beast' by enthusiasts for its sharp handling and powerful torque delivery. Production continued until 2013, when it was succeeded by the 1290 Super Duke R, leaving behind a strong legacy as one of the most exciting naked bikes of its era.

What Buyers Should Know
Watch the Cam Chain
The LC8 V-twin engine is known for cam chain tensioner wear, especially on higher-mileage bikes. Always check for a rattling noise on cold starts before buying.
Strong Resale Value
The 990 SuperDuke holds its value well due to its cult following and limited production years (2005–2013). A well-maintained example commands a premium in the used market.
Raw, Unique Character
The 999cc LC8 engine produces around 120hp with a distinct aggressive V-twin character that modern naked bikes rarely replicate. It's considered one of the purest street fighters ever made.
Generations & Specs by Year
Initial launch with 999cc LC8 V-twin, tubular steel frame, WP suspension, aggressive naked styling.
"Unhinged Austrian madness that actually works brilliantly."
The LC8 V-twin doesn't just pull — it physically tries to rotate the bike beneath you mid-corner, and the first time that torque surge hits around 6,500 rpm you genuinely question your life choices. I put 14,000 km on mine including a Pyrenees run and daily London commuting, and nothing else on the market in 2005 felt this savage or this focused on feedback. The WP forks are properly adjustable and planted, though the rear shock needed a rebuild by 12,000 km — budget for that. Vibration through the pegs and bars is real above 7,000 rpm, the stock seat will destroy you after two hours, and early examples had a fuelling glitch at small throttle openings that KTM quietly revised partway through the production run.
Pros
Cons
Revised fuel injection mapping, updated exhaust system, minor ergonomic and cosmetic refinements introduced.
"The angriest, most addictive naked bike alive."
The revised fuel injection on the Gen 2 smoothed out the worst of the Gen 1's low-rpm snatch, and the 999cc LC8 now pulls cleanly from 3,000 rpm without hunting — a genuine improvement you feel immediately in traffic. Above 6,000 rpm this thing turns savage in the best possible way; 118 horsepower in a 189 kg chassis means every throttle input feels consequential, and the front wheel attitude is less a question of 'if' than 'when.' The updated exhaust note is deeper and more authoritative, though it's still happily antisocial past 8,000 rpm. What nobody tells you: the vibes are real, your hands go numb on a two-hour stint, and the seat is essentially an orange park bench bolted to a race chassis.
Pros
Cons
Updated electronics, revised throttle body, improved braking components, new color schemes and graphics.
Final production years, subtle refinements, R model with Brembo brakes and fully adjustable WP suspension offered.
Used Buyer Review
"Raw, rewarding, and ruthlessly unforgiving of neglected maintenance history."
$4,500-$8,500 usedThe 990 SuperDuke is basically a street fighter that never got the memo about being civilized. That LC8 V-twin is an absolute animal — raw, torquey, and loud enough to rattle fillings loose. It rewards experienced riders who want involvement over comfort, and punishes anyone who treats it casually. The ergonomics are aggressive but not punishing for medium-length rides, and the handling is razor-sharp even by modern standards. Buying used, you need to be ruthless about maintenance history. The LC8 engine eats cam chain tensioners if owners skipped services, and that repair gets expensive fast. Check the throttle bodies for synchronization issues and inspect the frame for stress cracks around the steering head — these bikes get ridden hard. Suspension components wear quickly on thrashed examples, so budget for a full service regardless. Avoid anything that's been tracked without receipts proving the work was done afterward.
