Welcome to the 2026 Rider Sponsorship Program — Conor Tebbe 🔥

Conor is the definition of grit, growth, and belief in the underdog. He’s been pushing the limits of what’s possible on a CFMoto machine, building brand awareness the hard way — through results.

🏆 2024 MOXC 4x4 Farmers Class Champion
🥈 2025 MOXC 4x4 Bandits – 2nd Overall
• 1 Win
• 3 Second-Place Finishes
• 1 Fourth-Place Finish

Now he’s not slowing down — he’s stepping up.

For 2026, Conor is moving into the MOXC 4x4 Aces Class and will be lining up at select rounds of the Grand National Cross Country (GNCC), including the legendary Kenda 9 Hours of Havoc. He’ll also compete in the GNCC 4x4 C Class as he expands his program.

After racing a CForce 600 the past two seasons, he’s making the jump to the CForce 1000 for 2026 — ready to bring even more power to the fight.

Since the age of 10, Conor has been driven to grow ATV racing and represent the sport with professionalism. He competes with heart, carries himself with purpose, and shows up prepared to leave it all on the track.

2026 isn’t about participation — it’s about impact.

We’re proud to have you in the program, Conor. Let’s get to work. 💪

🏁🏆 WORLD FINALS CHAMPIONS! 🏆🏁

Huge congratulations to Nate Bay , Jesse Burns, Andrew Barnard and the entire team on taking the win at the IHRA Snow Outlaw World Finals in Three Lakes, Wisconsin!

Winning at this level in Pro Mod is no small feat — it takes horsepower, precision, and a dialed-in setup from the line to the stripe. We’re proud to say Nate’s Pro Mod snowmobile was running our STM air primary and secondary clutches when he brought home the championship.

Here’s what Nate had to say after the win:
“Good afternoon, just wanted to send a thank you for your great products. I run an air primary and secondary STM clutches and won the Snow Outlaws World Finals at Three Lakes Wisconsin.”

That’s what it’s all about — performance you can trust when it matters most.

Congratulations again to Nate and the entire team. Thank you for trusting STM Powersports to be part of your program.
