KTM’s 390 Duke has been the shining star of the brand’s LAMS lineup since its introduction, but for 2024 things look to get even better for fans of KTM’s pint-sized Duke.
For the new model year, the 390 Duke has undergone a complete redesign, with a new 399cc engine, an all-new chassis concept, and new styling which amplifies that aggressive KTM DUKE design language we’ve come to expect.
KTM is calling its new engine the LC4c - drawing a clear parallel with the larger displacement LC8c which powers the 790 and 890 Dukes. Displacement has been bumped up by giving the LC4c a longer stroke than the previous 390 engine with bore and stroke now 64mm x 89mm - previously 60mm x 89mm. Power from the new larger displacement engine is rated at 44bhp (33kW) which is backed by 39Nm of torque, an increase of 1kW and 2Nm over the 2023 model. A quickshifter is once again an optional extra for the 390 Duke. Naturally, the new engine meets the latest Euro5+ emissions standards, which would explain the modest increase in power despite the extra 25cc of capacity.
The chassis is all new with a steel trellis main frame matched to a pressure die-cast aluminum subframe. KTM states the primary objective for the new frame design is to enhance dynamics by augmenting torsional rigidity, allowing for improved agility and enhanced feedback from the chassis. Ensuring best-in-class handling, stability and comfort. This has come at a weight cost, however, with KTM listing weight without fuel as 165kg.
As with the previous generation, the suspension is handled by WP Apex units at both ends while the rear shock mounts to an all-new curved lightweight swingarm which contours around the relocated rear shock absorber. KTM says moving the rear shock absorber off-centre allows for an optimally positioned airbox while reducing seat height and allowing for a new muffler design.
That lower seat height now measures in 10mm lower at 820mm without the optional low seat which drops seat height a further 20mm.
An all-new lightweight wheel design reduces rotating unsprung mass, improving overall
handling characteristics. This was achieved by having fewer spokes and an open hub design, optimised to accommodate the new brake setup. This, combined with the lighter front brake disk and hollow front axle make for a much lighter front end according to KTM.
Apart from the physical changes to the 2024 390 Duke, KTM has also given the bike a new electronics suite led by a new 5” TFT and new switchgear. The new 5 “TFT dash also allows 2024 KTM 390 DUKE riders to toggle between ride modes, adjust the MTC and initiate Launch Control.
It is also equipped with connectivity functions, such as a music player via the KTMconnect app, and the ability to answer incoming calls, and Turn-by-turn navigation.
The 2024 390 Duke certainly appears to be a formidable package in an increasingly tight market segment.
New Zealand arrival and pricing are yet to be announced by KTM New Zealand.
