JACKSONVILLE, Fla. — The wait is just about over for the Maxxis 4-Cycle Sprint Series and its competitors as the tour’s 2021 campaign will kick off this Friday and Saturday at the fast 103rd Street Sports Complex in Jacksonville, Fla.
A full day of practice and a big Saturday of racing will open the new season at the popular 0.5-mile course that features its coveted 1,000-ft straightway, banked “Monza” corner and plenty of sweeping, high-speed corners. The 103rd Street course, which is a 14-acre park owned by the City of Jacksonville and helped maintained by the North Florida Kart Club, is widely viewed as one of the most well-known and unique kart tracks in the eastern United States, and the Maxxis opener will serve as the venue’s first big national event of 2021.
This weekend will mark the start of the Maxxis Sprint Series’s fourth season and it will open a six-race schedule that culminates with a return trip to Jacksonville for the fourth annual Grand National Final November 19-21. National events at Barnesville, Ga., Charlotte Motor Speedway, Sandy Hook, Md., and Kershaw, S.C.’s Carolina Motorsports Park will fill the schedule between this weekend’s opener and season-ending Grand Nationals.
Eleven classes are on the docket with eight mandating the Briggs & Stratton LO206 powerplant plus three Vintage divisions.

Cadets and juniors each have two divisions from which to choose. The cadet racers can compete in Green and/or Yellow while the juniors are offered Black and/or Yellow. Kid Kart, Senior Medium (360#), Senior Heavy (380#) and Masters (390#) complete the LO206 class list.
For vintage racers, they’ll have Stock Medium, Stock Heavy and Super Stock available for competition.
Pre-entries have continued to steadily flow in right up until the cut off Wednesday night, April 7. Teams will still be able to enter at the track for a slightly higher fee.
We’re looking forward to attending and covering all of Saturday’s action and we’ll post updates, photos and video on The Kart Lounge Facebook all day Saturday plus offer a complete recap including audio interviews from many of the day’s top finishers.
