Kestrel Take

The 'Super Scalpel' — KTM's 890 Duke is a razor-sharp middleweight naked with a punchy parallel-twin and hooligan attitude, lighter and more focused than the bigger super-nakeds. It's a blast, but KTMs get ridden hard and need attention to maintenance. A clean, well-serviced 890 Duke with records is one of the most fun middleweight nakeds going; verify service and inspect for abuse.
