Henry Snell Crowned 2025 AJN Steelstock Kawasaki British Superteen Champion

Having dominated the season so far, Australian rider Henry Snell was crowned the 2025 AJN Steelstock Kawasaki British Superteen Champion at Donington Park following his 11th win of the year.

Since his double victory at the opening round of the season at Oulton Park back in May, ROKiT Rookies Kawasaki’s Henry Snell has been the rider to beat for the AJN Steelstock Kawasaki British Superteen riders. In his second season in the class, the likeable Aussie has powered his Ninja ZX-4RR to 11 victories and a further two podiums so far, seeing him wrap up the title with one round to go. 

Yet despite his dominance, it has been far from an easy season for Henry, facing stiff competition from title rival James Cook alongside podium challengers Marley Mackenzie, Freddy Oakley, Callum Beach, Greg Marshal, Kylan Shuttlewood, Luca Hopkins, David Lindemann and Troy Jeffrey. This ensured bar-to-bar racing throughout, with many races decided on the final lap. 

2025 will mark the final year of the AJN Steelstock Kawasaki British Superteen Championship, with the series now evolving into the National Junior Sportbike class. The ever-popular Ninja ZX-4RR remains eligible for the new series, and Kawasaki UK and Team Green are continuing to support younger riders by offering a race-ready package. Riders interested in learning more should contact Ross Burridge at Kawasaki UK (marketing@kawasaki.co.uk) or Nick Morgan at MSS Performance (info@mssperformance.com).   

Ross Burridge, Head of Marketing & Racing Department at Kawasaki Motors UK:
“It has been another fantastic season of the AJN Steelstock Kawasaki British Superteen Championship, and with one round still to go, the drama is far from over. Henry is a thoroughly deserved champion, though, and has proven to be the dominant rider all year, taking an incredible 11 wins from 14 races. 

With nine other riders joining him on the podium, it shows just how competitive the series is, and we’re all looking forward to seeing where Henry and the rest of the field go in their careers.”

AJN Steelstock Kawasaki British Superteens Comes To A Close

Following two thrilling seasons of bar-to-bar racing, 2026 will see the series evolve into the all-new National Junior Sportbike Championship. Kawasaki and Team Green will continue its ethos of supporting the next generation of racers by offering a special race package for those riders looking to campaign a Ninja ZX-4RR in the new series.


Since its launch last season, the Kawasaki British Superteen Championship has proven to be one of the most action-packed in the entire BSB paddock, providing thrilling racing and close finishes in almost every race. It has also showcased the Team Green ethos of supporting young riders, with a number of last season’s leading names moving onto the next stage in their career, such as Chloe Jones, who has been competing in the Women’s Circuit Racing World Championship, Ted Wilkninson in the National Sportbike series, and Carl Harris in the British Supersport class.

This season has been dominated by Henry Snell, who will have his first chance at wrapping up the title this weekend at Donington Park, but it has been far from easy for the Australian as future stars James Cook, Freddy Oakley, Marley Mackenzie and a whole host of other riders have pushed him all the way in what has been an unforgettable season.

Following the huge success of the National Sportbike Championship, for 2026 onwards, the British Superteen Series will be replaced with the National Junior Sportbike Championship. This new series will allow any manufacturer to enter with a model that offers an upper power parameter of 73 PS, which means the race-proven Kawasaki Ninja ZX-4RR remains eligible and ultra-competitive for the new Championship.

Kawasaki UK and Team Green will continue to support younger riders by offering a race-ready package for those teams who choose to use the Ninja ZX-4RR in the new class. If you are interested in doing so, please contact Ross Burridge at Kawasaki UK (marketing@kawasaki.co.uk) or Nick Morgan at MSS Performance (info@mssperformance.com).

Ross Burridge, Head of Marketing & Racing Department at Kawasaki Motors UK:

We have seen two fantastic seasons of racing in the AJN Steelstock Kawasaki British Superteen Championship, and it has been the perfect platform for helping riders onto the next stage in their career, as we have seen so clearly with Chloe, who took her maiden World Championship podium earlier this season.

We are excited to be continuing to support these young riders in the new National Junior Sportbike Championship, where we’re sure the Ninja ZX-4RR will be a formidable force.

I would like to thank Alan and his team at AJN Steelstock for their support and involvement as title sponsors of the series this year. We would also like to extend a huge thank you to MSS Performance for their assistance with technical support, plus series partners Fuchs Silkolene, GB Racing, K-Tech suspension and Vesrah. We hope to continue working with all partners on the Ninja ZX-4RR race package available for the National Junior Sportbike Championship in 2026.”
