sonic chopperSylvain Guintoli, former WorldSBK champion, is auctioning a one-of-one Sonic-inspired motorcycle to raise money for his late son, Luca.Back in 2024, the motorcycle racing community held its breath as former WorldSBK champion, 24 Hours of Le Mans winner, and TMT MotoGP pundit Sylvain Guintoli stepped away from our screens. We didn't hold our breath because he was gone, but rather because he left to look after his son, Luca, who had been diagnosed with cancer. When we released the breath trapped in our lungs, it came with a quiver at the news that Luca had passed away on July 30, 2025, at just six years old. Since then, Guintoli has plowed full steam into raising money for the Luca Guintoli Foundation, which promotes and protects the physical and mental health of children who have autism or cancer. The foundation aids families in England and Wales through the provision of financial assistance, support, education, and practical advice.Recently, Sega donated a piece of memorabilia to the Luca Guintoli Foundation, which is thought to be the first time the company has donated memorabilia. The item in question is a one-of-one custom motorcycle inspired by Shadow the Hedgehog from Sega's Sonic the Hedgehog franchise. The motorcycle was created for the 2024 Fearless: Year of Shadow campaign. The bike is a head-turner and was created and designed by Sega in conjunction with Oil Sweat & Gears and Atmospherics SFX.screenshot-2026-08-25-at-93629pmPhoto by: BonhamsAll Things Sylvain GuintoliDrag Race: Strongman Eddie Hall, The TTS SuperBusa, And An AirstripCan A Track Day Enthusiast Catch MotoGP Test Rider Sylvain Guintoli?AdvertisementAdvertisementIt might seem like a somewhat random piece of machinery to gift Luca's foundation, but that's far from the case. Sonic was Luca's favorite character, and a lot of the fundraising for the foundation is Sonic-themed. The bike's spec sheet, however, is far less cute than the character it's based on, sporting a 1,750cc S&S Super Stock engine equipped with Edelbrock cylinder heads, which is mated to an Ultimate six-speed gearbox. The whole thing weighs a staggering 617 lbs, is 2.6 meters long, 1.1 meters high, and 900mm across the handlebars.It should be noted that this motorcycle is currently configured for static display and cannot be used on the road in its present form. Commissioning it for road use would have to include replacing the fuel tank (currently a foam dummy) alongside various other recommissioning tasks. The auction house, Bonhams, isn't taking commission for the sale, which is expected to fetch £10,000 - £15,000 ($13,654 - $20,481).This donation adds to the heartwarming list of fundraising actions in the wake of Luca's passing, including Guintoli running the London marathon this year while wearing a full racing suit. With a time of 3:47:47, Guintoli unofficially broke the Guinness World Record for the fastest marathon run in motorcycle clothing, and raised more than £140,000 ($191,128) in the process.
