The KTM 990 Super Duke was introduced in 2005 as a naked streetfighter built around KTM's LC8 V-twin engine, earning the nickname 'The Beast' for its aggressive power delivery and radical styling. It evolved through several updates including the R variant in 2007 which brought WP suspension upgrades and improved components. The 990 Super Duke remained in production until 2013, cementing its reputation as one of the most visceral and exciting naked bikes of its era before being succeeded by the 1290 Super Duke R.

What Buyers Should Know
LC8 Engine Quirks
The 999cc LC8 V-twin is a powerful but maintenance-intensive motor — valve clearances should be checked every 15,000 km and are often neglected by previous owners. Always verify service history before buying.
Watch the Throttle Bodies
A known issue on the 990 Super Duke is throttle body synchronization going out of tune, causing rough idle and uneven power delivery. It's a cheap fix but commonly overlooked, so budget for a tune-up.
Strong Resale Value
The 990 Super Duke holds its value surprisingly well due to its cult following and reputation as a raw, engaging naked bike. Well-maintained examples remain in demand even 10+ years after production ended.
Generations & Specs by Year
Original 999cc LC8 V-twin, trellis frame, naked supermoto styling; minor updates over run.
"The angriest naked bike Austria ever bolted together."
That LC8 V-twin doesn't just pull — it snarls, spits, and drags your forearms out of their sockets between 4,000 and 7,500 rpm in a way no inline-four ever will. I ran one for two years on daily commutes and weekend canyon runs, and the trellis chassis is so direct it borders on telepathic — flick it and it goes, no debate. The honest weaknesses: the seat turns to concrete after about 90 minutes, the fueling on early models is lumpy below 3,500 rpm until you remap it, and reliability means keeping an eye on the throttle bodies and that temperamental sidestand switch. It also vibrates your mirrors into uselessness above 130 km/h, but frankly, above 130 km/h on a Super Duke you're too busy grinning to check them.

Used Buyer Review
"A flawed, thrilling machine that rewards the diligent buyer handsomely."
$4,500-$8,500 usedThe 990 Super Duke is the motorcycle that either converts you or terrifies you within the first mile. That LC8 V-twin is an absolute animal — raw, torquey, and completely unfiltered in a way modern bikes simply aren't anymore. KTM built something genuinely special here, and the used market knows it. Prices have actually crept back up as people realize what they had. Buy one right and it'll reward you endlessly. Buy one wrong and you're funding someone else's neglect. These bikes attracted riders who rode hard and occasionally maintained soft. Check the frame for stress cracks around the headstock, inspect the WP suspension for leaks, and verify the throttle bodies have been synced recently. The subframe bolts love to work loose. Coolant hoses crack with age. None of it is catastrophic if you know going in. Above all, get a pre-purchase inspection. A good one costs $150 and could save you $2,000. The 990 is worth owning — just own a healthy one.
