EXPLAINED: KTM/HUSKY/GASGAS ENDURO GEARING

Why do the new-gen enduro models from KTM, Husqvarna and GASGAS (ie, the 2024 models onwards) now come with final gearing that seems better suited to desert racing than trailriding? KTM Group’s Technical Services Manager, Rob Twyerould, explains…

The previous generation enduro models from KTM, Husky and GASGAS all ran what was considered ‘conventional’ final gearing, with a 14/50 or 14/52 sprocket combo used across the enduro model range. When the new-gen bikes arrived for 2024, however, everyone started asking why the hell the rear sprockets that came on the bikes were suddenly so small and why, for some 2025 and 2026 models, that gearing was made even taller (for example, the 2026 300cc two-strokes all come with 14/42 gearing).

So, why the sudden change to final gearing that seems better suited to desert racing that trailriding? Has it got something to do with the new Euro5+ noise emission regs? Or with the new, standardised transmissions introduced for the 2024 enduro machines? Or is it the result of something else entirely?

With many consumers confused about the late-model bikes’ gearing, we called on the KTM Group’s technical guru, Rob Twyerould, to help explain…
