Agility Meets Authority

Since clinching the 2016 Enduro GP World Championship with Australian legend Matthew Phillips, the 2020 Junior World Championship with Kiwi Hamish MacDonald, and dominating the 2023 Australian Four Day Enduro with Jonte Reynders, the Sherco 300 SEF Factory has evolved into a race-proven, ultra-refined machine built for champions.
