In a major coup for the Penrite ProMX Championship presented by AMX Superstores (ProMX), legendary British marque Triumph joined the paddock in 2025 with the talented Jack Simpson leading the charge in MX1 on the Winner Triumph Racing TF 450-RC.
Simpson will be one of three riders in the Winner Triumph Racing Australia Team, with the Victorian-based Winner Motorcycles switching brands for 2025 with key support from Peter Stevens Motorcycles and Triumph Motorcycles Australia.
With the local motocross scene dominated by Japanese and European manufacturers, the arrival of Triumph is a real shot in the arm for the ProMX Championship.
Simpson will ride Triumph’s flagship TF 450-RC – developed in conjunction with motocross legend Ricky Carmichael – in the MX1 category, and in the Pirelli MX2 class, Connar Adams and Thynan Kean will race the TF 250-X.
Following the audacious launch of a motocross range – the TF 250-X followed by the TF 450-RC – alongside its road-based families, Triumph’s impending ProMX debut comes on the back of the marque’s major commitment to various off-road championships around the globe, including the Motocross World Championship, EnduroGP and AMA Supercross.
At the time of going to press, Triumph’s biggest result was Jordon Smith’s victory in the AMA 250 SX West round in Glendale on 2 February.
The Rider – Jack Simpson
“I am so excited to be back to my roots and racing in Australia,” said Simpson. “My last ProMX season was all the way back in 2015 and since then I have travelled the world racing in off-road, desert and more.
“To come home this year and have the honour of racing the TF 450-RC is amazing and I want to thank Winner Triumph Racing Australia for this opportunity.”
Simpson, a former MX3 contender, Australian off-road champion, and desert racing star, returns to Australia after a successful five-year stint competing in America. With experience across multiple disciplines, he is expected to bring both speed and racecraft to Triumph’s MX1 campaign.
Team Owner – Karen Adams
Winner Motorcycles Racing program owner Karen Adams is delighted to be partnering with Triumph.
“To sign this deal to be an official racing partner for an esteemed brand such as Triumph is a remarkable milestone,” said Adams. “This will be a learning year, but I’m confident that between our infrastructure, the Triumph platform and our riders, [this] will enable us to be competitive as the season progresses.”
With the backing of Triumph Motorcycles Australia and Peter Stevens Motorcycles, the Winner Triumph Racing Australia Team is set to make a strong impact as it prepares for the 2025 ProMX Championship.
