Sponsorship

Spartek loves to get involved and support local communities and sponsorships. One of our latest sponsorships is with Mini Rossi.

Yes, Rossi, as in the legendary Italian racing driver, former professional motorcycle road racer, and nine-time Grand Prix World Champion!

But this is Mini Rossi is 16 and her name is Isobel Carter and already tipped to be a top contender in the racing world.

Hailing from Banham, Norfolk, 16-year-old Izzy has been turning heads in the motorcycle racing world from a remarkably young age. Nicknamed “Mini Rossi” in tribute to her idol, MotoGP legend Valentino Rossi, Izzy embodies the passion, skill, and determination that Spartek is proud to support.

Izzy’s racing journey began early, and by age 11 she was already being hailed as a future star. In 2025, she’s competing in the British Motorcycle Racing Club (Bemsee) series on a Kawasaki Ninja 400. Later this year, she’ll make her debut on a Yamaha R7, now backed by Spartek, as she pursues her dream of racing in the Women’s World Championship (WCR).

With a strong social media presence including her Instagram account @mini_rossi, Threads, and YouTube Izzy shares behind-the-scenes insights, race day highlights, and her journey as a young racer. Her growing fanbase and media attention reflect not just her talent, but her engaging personality and unwavering dedication to the sport.

Izzy’s admiration for Valentino Rossi runs deep. At just 8 years old, she was featured in a national article as perhaps the world’s biggest Rossi fan having met him and even sat on his bike. That moment sparked a fire that continues to drive her forward.

At Spartek, we believe in backing passion and ambition and Izzy Carter is the perfect embodiment of both. We’re proud to support her journey and can’t wait to see what she accomplishes next. Keep your eyes peeled for the new bike and Graphics.

Follow her journey at @mini_rossi and keep an eye out for more updates as the 2025 season progresses!
