Overview

The second-generation 390 Duke introduced aggressive styling inspired by the Super Duke 1290, a full-colour TFT dash, and ride-by-wire throttle. It is a fantastic handling, punchy single-cylinder bike that thrives on tight, twisty roads. While reliability improved massively over the first generation, it still requires more attentive maintenance than its Japanese rivals.

Known problems

medium
TFT dashboard water ingress
The TFT dashboard on early 2nd-gen models is poorly sealed. Water from heavy rain or aggressive washing can enter the unit, causing condensation, screen blanking, or complete failure.
Fix: Many were replaced under warranty. If out of warranty, replacements are expensive; check for condensation spots before buying.
Any · ~$800-1200
low
Engine stalling
The ride-by-wire system and lean factory tuning can occasionally cause the bike to stall abruptly when pulling the clutch in at low speeds.
Fix: Usually resolved by ensuring the ECU software is fully updated at a KTM dealer.
