KTM Validates 2026 RC16 Updates, Ends P2 Behind Ducati

KTM arrived at the Sepang test with a revised 2026 RC16 package — a new chassis concept, updated aero parts and a new swingarm — and split its factory program between development and consolidation. The manufacturer completed the opening day as the second-fastest on the timesheets behind Ducati, with Tech3’s Maverick Viñales posting a late 1:57.295 that underlined early pace while KTM used the day to validate the new parts. The team ran a dual approach: Pedro Acosta concentrated on chassis and aerodynamic development, while Brad Binder followed a more conservative program aimed at regaining outright speed.

Acosta, 21, described the new shortened chassis as “promising” and said the configuration was “working,” but he also reported unusual vibrations from the very first lap and limited his opening-day running. He spent his morning exploring chassis setups, used more of his tyre allocation than planned, completed an early medium-tyre run before switching to softs, and finished 15th on the combined times; he left the day planning further aero work to improve turning and front-end stability. Acosta’s program prioritized feel and component evaluation over time-attack laps, and KTM noted these early mechanical and stability signals while managing run plans.

Binder, 30, posted consistent lap times around 2:00.2–2:00.3 and initially rode the same chassis he used in Valencia, reporting little chattering as he worked on pace. He also compared the new swingarm against the older design to assess differences while Acosta focused on aero and chassis feel. Both riders and the factory expected Wednesday to be the main day for further aerodynamic and component evaluations, and KTM said a more definitive assessment of tyre behavior and the updated package should become clearer by the later days of the test. The opening session therefore underscored KTM’s two-track strategy and highlighted the specific areas — front-end stability, vibrations and tyre behavior — that the team needs to address before the season.
