Ktm Super Duke 990 Review

Used Buyer Review

The 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.
