Kid Classes

Kid Kart
Age: 5-8 Years Old
Engine: Comer C-50 or C-51 50cc 2-Stroke
Chassis: Small
Minimum Weight: NA
Top Speed: 25 MPH (10/89 Spec Gear)
This class is for the youngest racers to develop basic driving skills along with their hand/eye/foot coordination. Generally there’s not much wheel-to-wheel competition. This is also where Dads learn the basics of working on a kart, and most importantly lay the bed for a positive working relationship with their child. The more fun both have, the better they do. Every time.

Cadet
Age: 8-12 Years Old
Engine: Comer K-80 80cc 2-Stroke
Chassis: Small or Intermediate
Minimum Weight: 235lbs
Top Speed: 40 MPH (10/53 Spec Gear)
A great class for kids to solidify their driving skills and coordination. The boys and girls who start in this class catch on pretty quickly. They start paying attention to their times and enjoy passing each other.

Micro Max
Age: 7-10 Years Old
Engine: De-tuned 125cc 2-Stroke Rotax Max TaG Engine
Chassis: Small
Minimum Weight: 235lbs
Top Speed: 35 MPH (14/73 Spec Gear)
Rotax MaxChallenge Rules Apply (Including Mojo Tires)
She same exact goals as all kid kart classes: developing basic driving skills and coordination. The key difference is the sealed Rotax engine, which gives a bit more speed, but also the flexibility to up-grade as the driver ages. This is a spec class, which means everyone runs the same sealed engine, tires and gear ratio. The mechanic (often Dad) can make a difference with chassis set-up and carb jetting, but primarily it’s up to the young racer to win with better driving. (See the Rotax note below.)

Mini Max
Age: 9-12 Years Old
Engine: De-tuned 125cc 2-Stroke Rotax Max TaG Engine
Chassis: Intermediate
Minimum Weight: 265lbs
Top Speed: 45 MPH (13/82 Spec Gear)
Rotax MaxChallenge Rules Apply (Including Mojo Tires)
The second rung on the ladder of sealed Rotax engines. It is tuned to be a bit faster, corners are taken a bit quicker, and the spirit of competition starts to heat up. As with Micro Max, this is a spec class where everyone has the same sealed engine and gear ratio, and the best driving earns the biggest trophy and biggest smiles.

TaG Classes

TaG Junior
Age: 12-15 Years Old
Engine: Rotax Junior Max or other De-Tuned 125cc 2-Stroke TaG Engine
Chassis: Full-Size
Minimum Weight: 320lbs
Top Speed: 65 MPH
Some kids work their way up to this class, others enter the sport here. In either case it’s exciting to watch the quick progress as they harness the speed and learn how a full-size kart should feel through a corner. It’s here they start working for every tenth of a second, and honing their wheel-to-wheel race craft.

TaG Senior
Age: 15+ Years Old
Engine: Rotax Senior Max or other 125cc 2-Stroke TaG Engine
Chassis: Full-Size
Minimum Weight: 365-380lbs Depending Upon Engine (See Classes & Weights)
Top Speed: 80 MPH
It’s graduation time! This class features unrestricted 125cc TaG engines strapped to full-size karts. While most kids in this class have spent at least a year or two in TaG Jr., even the beginners catch on quickly as they work to keep up with the competition. More than a few lightweight adults run this class and enjoy the challenge of out racing kids half their age!

TaG Masters
Age: 32+ Years Old
Engine: Rotax Senior Max or other 125cc 2-Stroke TaG Engine
Chassis: Full-Size
Minimum Weight: 380-405lbs Depending Upon Engine (See Classes & Weights)
Top Speed: 80 MPH
One of our most popular classes, TaG Masters grids are often 20 karts deep, making for some of the most competitive club racing anywhere. But we all race each other knowing we gotta go to work Monday morning! Masters karts are set up with more weight than Senior karts to help level the playing field for heavier drivers. If you’re an adult who always wanted race, this class is your dream come true!

About Rotax Engines
The Rotax FR-125 MAX is the original push-button start engine for TaG (touch and go). Their stout power, reliability, and availability of parts and service make them the most popular engine in the NHKA Racing Series. Another unique advantage is their evolution concept where a single engine can be adapted for every stage of a karter’s career – from the youngest Micro Max kid to a 32+ year old Masters racer.

4-Cycle Classes

LO-206 Cadet
Age: 7-12 Years Old
Engine: Briggs and Stratton LO206 with the Gold .505″ restrictor Plate
Chassis: Full-Size
Minimum Weight: 275lbs
Speed: 30 MPH
4-cycle karts are a perfect entry point for kids just getting into the sport or transitioning from indoor karts. The LO-206 sealed engine is affordable and reliable which keeps the focus on the fun of racing.

LO-206 Junior & World Formula Junior
Age: 12-15 Years Old
Engine: Briggs and Stratton LO206 or World Formula with carburetor slide limiter
Chassis: Full-Size
Minimum Weight: 310lbs
Speed: 40 MPH
For the kids coming up from LO-206 Cadet, LO-206 Junior is where the restrictor plates come off. But there are just as many kids who enter the sport at this age. For these rookies, we recommend the World Formula engine detuned for the Junior class with a simple and inexpensive carburetor slide limiter. That way they could possibly race the same exact engine for the rest of their lives. At this age the kids really start to work on their driving. Because the engine rules dictate everything be box-stock, the races are won by the fastest kid rather than the richest dad.

World Formula Light and Heavy
Age: 15+ Years Old
Engine: Briggs and Stratton World Formula
Chassis: Full-Size
Minimum Weight: Light 360lbs / Heavy 390lbs
Top Speed: 65 MPH
With speed and power halfway between indoor karts and TaG karts, World Formula is a great entry to outdoor racing for teens and adults. Thanks to box-stock rules and the relatively low purchase price of the engine, this is the perfect class for new and experienced racers just looking to have a bit of fun. What’s more, their reliability make them perfect for the less mechanically inclined. No wonder this is our fastest growing class.

Shifter Classes

125cc Shifter
Age: 15+ Years Old
Engine: Various 125cc 2-Strokes with a 6-Speed Manual Gearbox
Chassis: Full-Size with Front Brakes
Minimum Weight: Honda Stock Moto 405lbs/All Others 385lbs
Top Speed: 100+ MPH
The ultimate thrill ride in kart sprint racing! You get big-time speed and power and the coordination challenge of shifting, braking and turning all at the same time while maintaining maximum momentum. Shifter racing has enjoyed a resurgence with the Northeast Shifter Kart Series. Come to an NHKA race and chat with our shifter racers, some of whom also run that series.

DD2
Age: 15+ Years Old
Engine: Rotax 2-Stroke with a 2-Speed Paddle Shift
Chassis: Full-Size Specifically Built for DD2
Minimum Weight: 385lbs
Top Speed: 90 MPH
The DD2, like its predecessor the RM1, is a set engine/chassis package. It features a push-button starter, chainless direct-drive system, and a 2-speed gearbox operated by paddles at the steering wheel. These unique packages are a lot of fun to drive!

2-Cycle Classes

(These classes are not run at F1 Outdoors due to sound restrictions)

2-Cycle Junior
Age: 12-15 Years Old
Engine: 100cc Piston Port 2-Stroke with a “can” exhaust
Chassis: Sprint Enduro
Minimum Weight: 320lbs
Top Speed: 65 MPH
This is the classic combination of chassis and engine (typically a Yamaha KT-100) that teaches the rewards of smooth driving and maintaining momentum. The skills learned in these karts translate directly to any kart driven later. That said, this same set up can be raced from 12 years old right up through adulthood just by changing the exhaust from a “can” to a pipe.

2-Cycle Senior
Age: 15+ Years Old
Engine: 100cc Piston Port 2-Stroke with a pipe exhaust
Chassis: Sprint Enduro
Minimum Weight: 360lbs
Top Speed: 75 MPH
With a nod to old-school karting and the club’s road racing roots, we have a loyal contingent racers in this class. Ages range from 16 to 50 and beyond. It’s a fun and affordable way to go 2-stroke racing.
