Oops, I did it again…-B. Spears.

Our remarkable run in continued with Nico Orbezo dominating all weekend at the Race Rotax USA 🇺🇸 US Trophy finals New Castle Motorsports Park. This marks the 3rd US Nationals win at New Castle in 4 years for Fox prepared engines.

Special shoutout to Enzo DiGennaro, despite bad luck, took a heat win on track and was arguably the fastest kart on track all weekend.

Also, great driving from Landon Buher who ran in the front group all weekend after a long hiatus from Rotax racing.

As always, thank you to the teams and drivers that trust us with their power.

We are very excited to introduce our very own jetting app, Jetmax! Now every racer has access to the same jetting Fox + Son has used to power our engines to countless Rotax National wins and tickets. After many months of development and testing, we have successfully brought the same jetting algorithms we use on our dyno to a quick, easy-to-use app. We have also included all of our popular Rotax tuning tips that are found on our website, along with a handy, interactive gear chart. As we do with our website, we will continually update the app as we discover new/better tuning information. Anytime a new cylinder or part is introduced, the results all of the testing we do at the shop will flow directly to Jetmax. Available now for Apple or Android, links to the app are in our bio.

Stars Championship Series - Round One

Fantastic weekend for the team, highlighted by taking the win in the headline Pro class. had a great weekend as well, running up front in thw 22 kart field and finishing with a solid 6th place. Wes and Aidan came out of the weekend 1st and 5th in points.
*
Junior rookie .sammut put the junior class on notice with an impressive performance in . In only his second 125cc start, he led multiple laps in the final, had the 3rd fastest lap, and brought it home in P4 in a 23 kart field filled with Jr veterans.
*
Briggs veteran had an awesome debut with the team in . He ran up front through the heats and had a great P5 finish in the prefinal. Contact from behind on the start to the final sent him to the back of the field, but David put his head down and drove from P40 up to P22. More to come from this kid.

A special shoutout to as he took P2 in the Minimax championship, right behind Enzo. It was Parker’s first Rotax race, and he was oh so close to the ticket, beating out a crew of Rotax specialists from all over the world.
The is always good to us, as we have won here in multiple categories every year the event has been in existence.
Thank you to the teams and drivers that trust us with their power. And thank you to and for running a great event.
