Rule #1: You Need a Kart!

The NHKA Racing Series has classes for every speed and budget. We offer 2-cycle and 4-cycle paths that racers can follow from their 5th to 75th birthdays, from Kid Karts all the way to Masters – often with only minor changes. Also, we work very hard to keep our rules in line with other tracks and series to make it easier for you to race wherever you want. We’re always looking for ways to help you get maximum value and enjoyment out of your kart!

Directly below is a chart giving a brief overview of our championship classes and rules. Scroll down further to find detailed descriptions of each of those classes. We know, it looks overwhelming at first, but only a few of the classes will apply to the age of your driver. If you’re not sure which kart is right for you email NHKA Race Director and Co-Owner, Mike Camarra at cfmotor@aol.com You can also ask other racers by posting to our Facebook page. You should also acquaint yourself with our NHKA Authorized Dealers which offer the karts, parts and service you’ll need to race, and the trackside support to help you win. If you want to try before you buy, some shops will bring a kart to the track for you to rent.

2018 World Formula Rules

 

2-Cycle Classes

NHKA 2-cycle classes offer high-revving speed and power with enough mechanical challenge to keep the race going between events. The 2-cycle path starts with a restricted Comer or Honda powered Kid Kart, or a TaG (Touch and Go) Micro or TaG Mini. By the time drivers reach Junior age, they’re in full-size karts with fewer restrictions on their engines, which they can continue to race into the TaG Senior and TaG Masters age groups. Rounding out the NHKA 2-cycle classes are the classic 100cc Senior karts, and of course the Shifters!

Kid Kart
AGE: 5-8 Years Old
TOP SPEED: 25 MPH
ENGINES: 50cc 2-Cycle – Comer C-50, Comer C-51 or Honda HPD GXH50
GEARING: 8.9 Ratio
CHASSIS: Small, Baby Kart
MINIMUM WEIGHT: N/A
TIRES: Open, 4.50 Front and Rear
RULES: WKA Manufacturers Cup
This class is for the youngest racers to develop basic driving skills and 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 foundation for a positive working relationship with their child. The more fun both have, the better they do in the years ahead. Every time.
KART SPOTTING TIP: Kid Karts are so small they almost make the tires look big. You can tell this one has a Comer 2-cycle by the little gas tank on top of the engine. An adorable little driver (and crew chief) is also a pretty clue that you’re looking at a Kid Kart.

TaG Micro
AGE: 7-10 Years Old
TOP SPEED: 35 MPH
CHASSIS: 900mm-950mm Wheelbase, No Front Brakes, TaG USA Chassis Rules
TIRES: LeCont Red 4.60 Front and Rear
ENGINE: 125cc 2-Cycle TaG
ROTAX MICRO MAX:
– MINIMUM WEIGHT: 235lbs
– GEARING: 14/73
– RULES: USRMC Micro & Mini Rulebook, EVO or NonEVO (No Mixing Components)
IAME MICRO SWIFT:
– MINIMUM WEIGHT: 225lbs
– GEAR: Open
– RULES: TaG USA
The same exact goals as all kid kart classes: developing basic driving skills and coordination. The key difference is the engines, which give a bit more speed, but offer the flexibility to up-grade as the driver ages. They are closely matched, which gives the mechanic (often Dad) the chance to make a difference with chassis set-up and carb tuning. However, it is primarily up to the young racer to win with better driving.
KART SPOTTING TIP: The best way to tell you’ve spotted a TaG Micro, at least one with a Rotax Micro Max engine, is by the skinny little radiator.

TaG Mini
presented by Prospeed Kartsports
AGE: 9-12 Years Old
TOP SPEED: 45 MPH
CHASSIS: 950mm Wheelbase, No Front Brakes, TaG USA Rules
TIRES: LeCont Red 4.60 Front and Rear
ENGINE: 125cc 2-Cycle TaG
MINI ROK & IAME SWIFT:
– MINIMUM WEIGHT: 245lbs
– GEARING: Open
– RULES: TaG USA
ROTAX MINI MAX:
– MINIMUM WEIGHT: 245lbs
– GEARING: 12/76 or 13/82
– RULES: USRMC Micro & Mini Rulebook, EVO or NonEVO (No Mixing Components)
With Mini karts, the speeds are a bit faster, corners are a bit more challenging, and the spirit of competition starts to come alive. Our goal is for all racers to have a shot at winning no matter what brand chassis or engine they race, so we may make small adjustments to the rules. In TaG Mini the best driving earns the biggest trophy and biggest smiles.
KART SPOTTING TIP: Telling a TaG Mini apart from a TaG Micro takes a keen eye to notice that the ones with a Rotax engine have a full-size radiator.

TaG Junior presented by DRT North America
AGE: 12-15 Years Old
TOP SPEED: 65 MPH
CHASSIS: Full-Size, No Front Brakes, TaG USA Rules
TIRES: LeCont White, 4.60 Front, 7.10 Rear
ENGINE: 125cc 2-Cycle TaG
– IAME X30 – 29m Exhaust Header, 315lbs Minimum Weight, TaG USA Rules
– Rotax FR125 – Jr. Cylinder, 320lbs Minimum Weight, US Rotax MaxChallenge Rules
– Parilla Leopard – 30mm Exhaust Header, 315lbs Minimum Weight, TaG USA Rules
– PRD Fireball – 30mm Exhaust Header, 300lbs Minimum Weight, TaG USA Rules
Some kids work their way up to this class, others enter the sport here (usually with indoor karting experience.) 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 getting hungry for every tenth of a second, and honing their wheel-to-wheel race craft.
KART SPOTTING TIP: Being the youngest group to race a full-size chassis, TaG Junior drivers can look small in their karts. Having rear tires that are wider than the fronts set TaG Jr.s apart from the TaG Minis. TaG Jrs. with Rotax engines are most easily differentiated from TaG Sr. and TaG Masters karts by the lack of a red knob on the back of the cylinder.

TaG Senior presented by CFMotorsports
AGE: 15+ Years Old
TOP SPEED: 80 MPH
CHASSIS: Full-Size, No Front Brakes, TaG USA Rules
TIRES: LeCont White, 4.60 Front, 7.10 Rear
ENGINE: 125cc 2-Cycle TaG
– IAME X30 – 370lbs Minimum Weight, TaG USA Rules
– Rotax FR125 – 365lbs Minimum Weight, US Rotax MaxChallenge Rules
– Parilla Leopard – 365lbs Minimum Weight, TaG USA Rules
– PRD Fireball – 350lbs Minimum Weight, TaG USA Rules
– X125T – 370lbs Minimum Weight, TaG USA Rules
NOTE: Masters karts with front brakes must run at their Masters weight
It’s graduation time! This class features unrestricted 125cc TaG engines strapped to full-size karts. While most young racers 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 going up against racers half their age!
KART SPOTTING TIP: More than anything age and size of the driver are the most identifiable visual characteristics of TaG Seniors.

TaG Masters presented by RJT Racing
AGE: 32+ Years Old
TOP SPEED: 80 MPH
CHASSIS: Full-Size, Front Brakes Allowed, TaG USA Rules
TIRES: LeCont White, 4.60 Front, 7.10 Rear
ENGINE: 125cc 2-Cycle TaG
– IAME X30 – 410lbs Minimum Weight, TaG USA Rules
– Rotax FR125 – 405lbs Minimum Weight, US Rotax MaxChallenge Rules
– Parilla Leopard – 405lbs Minimum Weight, TaG USA Rules
– PRD Fireball – 390lbs Minimum Weight, TaG USA Rules
– X125T – 410lbs Minimum Weight, TaG USA Rules
One of our most popular classes, TaG Masters grids are typically 15+ karts deep, making for some of the most competitive club racing anywhere. It’s fierce, but they race each other knowing they all gotta go to work Monday. 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!
KART SPOTTING TIP: If you see front brakes but no shifter lever, you have most definitely looking at a TaG Masters kart. However, not all Masters competitors choose to run front brakes. However, this TaG Masters can be tricky little buggers… you might see one in the TaG Senior race, which is fine so long as they run their Masters weight if they have front brakes.

Rotax – The Original TaG Engine
The Northeast is where the Rotax FR-125 MAX and push-button start TaG (Touch and Go) classes began in the US, so you’ll see a lot of them around. With stout power, reliability and availability of parts and service, they remain popular. However, the TaG market has heated up with great new engine options such as the IAME X30 and others. Rotax has responded with a number of product updates, including the Rotax EVO package. A significant number of Rotax owners felt there were too many updates and switched brands. This has resulted in lots of affordable used Rotax packages and parts for sale at various stages of update. No need to pass-up these deals, especially if it’s your first kart and you’re short on funds. NHKA rules allow you to run any unaltered Rotax-made parts of any vintage so long as you don’t mix EVO and non-EVO parts, and they’re configured as directed by the US Rotax MaxChallenge rulebook. KART SPOTTING TIP: Karts with Rotax engines are easy to spot by their distinct two-part exhaust pipes.



100cc Pipe
AGE: 15+ Years Old
TOP SPEED: 85 MPH
ENGINE: 100cc Piston Port 2-Cycle, Pipe Exhaust, AKRA Rules
Chassis: Sprint Enduro, AKRA Rules
MINIMUM WEIGHT: 360lbs
With a nod to old-school karting, and the club’s road racing roots, this is the classic combination: sprint enduro chassis with full bodywork and a Yamaha KT-100 engine. This class teaches the rewards of smooth driving, maintaining momentum and a good pair of earplugs. It’s a fun and affordable way to go 2-cycle racing… just not at F1 Outdoors due to the track’s sound restrictions.
KART SPOTTING TIP: Full wraparound bodywork. Oh, and that noise!

4-Cycle Classes

NHKA 4-cycle classes offer the close competition of sealed, box-stock engines with low-maintenance reliability and affordability. The 4-cycle path is structured primarily around the Briggs 206 (formerly known as the Local Option 206 or LO-206.) A racer can start out in Kid Karts or Cadets, and race their way through Junior and Senior classes up to Masters with the same Briggs 206 engine simply by changing the $13 carburetor slide. Once at Senior age the NHKA offers the option to switch over to the higher horsepower Briggs World Formula engine. KART SPOTTING TIP: The easiest way to tell between 4-cycle and 2-cycle karts is to look with your ears… 4-cycles have a low rumble, where as 2-cycles have a high-revving whine. As for telling between Briggs 206 and World Formula karts, the 206 is orange and the World Formula is silver.

Briggs 206 Kid Kart
AGE: 5-8 Years Old
TOP SPEED: 25 MPH
ENGINE: Briggs 206, Long Black Carb Slide, 4,150rpm Black Ignition, MaxTorque clutch, Briggs 206 Engine Class Regulations
GEARING: 3.35 Ratio
CHASSIS: Small, Baby Kart, AKRA Rules
MINIMUM WEIGHT: N/A
TIRES: MG Red 4.60 Front and Rear
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 foundation for a positive working relationship with their child. The more fun both have, the better they do in the years ahead. Every time.

Briggs 206 Cadet
AGE: 7-12 Years Old
TOP SPEED: 30 MPH
ENGINE: Briggs 206, Red Carb Slide, Briggs 206 Engine Class Regulations
CHASSIS: Intermediate, No Front Brakes, AKRA Rules
MINIMUM WEIGHT: 265lbs
GEARING: 3.35 Ratio
TIRES: MG Red – 4.60 Front and Rear
4-cycle karts are a perfect entry point for kids just getting into the sport or transitioning from indoor karts. The Briggs 206 sealed engine is affordable and reliable which keeps the focus on the fun of racing.

Briggs 206 Junior
AGE: 12-15 Years Old
TOP SPEED: 40 MPH
ENGINE: Briggs 206, Yellow Carb Slide, Briggs 206 Engine Class Regulations
CHASSIS: Full-Size, No Front Brakes, AKRA Rules
MINIMUM WEIGHT: 310lbs
TIRES: MG Red, 4.60 Front, 6.00 Rear
For the kids coming up from Briggs 206 Cadet, 206 Junior is where the restrictor plates come off. There are just as many kids who enter the sport at this age. It’s at this point 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.

Briggs 206 Senior/Masters
AGE: 15+ Years Old
TOP SPEED: 50 MPH
ENGINE: Briggs 206, Stock Carb Slide, Briggs 206 Engine Class Regulations
CHASSIS: Full-Size, No Front Brakes, AKRA Rules
MINIMUM WEIGHT: Light 360lbs, Heavy 390lbs
TIRES: MG Red, 4.60 Front, 6.00 Rear
If you’re an experienced karter or just getting your start in the sport, a Briggs 206 might be the right choice for you… it certainly has been for a lot of people across the US and Canada. And no wonder given how affordable, reliable and simple to maintain the package is. The key difference between it and the Briggs World Formula (aside from having somewhat less power) is that you can pretty much race it at any kart track in North America without changing a thing. That includes prestigious national events like the Daytona Kart Week, Rock Island Grand Prix and 206 Cup events. How far you take your racing is completely up to you.

Briggs 206 – Compete Wheel-to-Wheel, not Wallet-to-Wallet
Have you ever wondered how good of a racer you or your kid might actually be? Let’s find out! Thanks to the Briggs 206 it’s never been easier or more affordable to scratch your racing itch. You can get a new race-ready 206 kart for about $4k, or bolt a new 206 engine onto a used chassis for about half that. This is pure spec racing. Everyone has the same tires, fuel and engine. Each 206 is hand built in the USA by Briggs & Stratton to incredibly tight tolerances then sealed to keep out the cheaters. You’ll be free to tune your chassis, but mostly you’ll focus on being the best driver. With basic maintenance, your Briggs 206 engine can deliver two competitive seasons without a rebuild, making it the perfect fit for racers with busy lives.

World Formula Light and Heavy presented by CFMotorsports
AGE: 15+ Years Old
TOP SPEED: 65 MPH
ENGINE: Briggs World Formula, Stock Carb Slide, NHKA World Formula Engine Program
CHASSIS: Full-Size, No Front Brakes, AKRA Rules
MINIMUM WEIGHT: Light 360lbs / Heavy 390lbs
TIRES: MG Red, 4.60 Front, 7.10 Rear on 7″ wheels
With speed and power halfway between indoor karts and TaG karts, and a bit beyond the Briggs 206, World Formula is a great entry to outdoor racing for older 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 has been such a fast growing class for the NHKA.
KART SPOTTING TIP: Aside from the obvious, to tell the WF Heavies from the WF Lights, just look for the older guys having the time of their lives.

Shifter Karts

Stock Moto Shifter
AGE: 15+ Years Old
TOP SPEED: 100+ MPH
ENGINE: 125cc 2-Cycle, 5 or 6-Speed Manual Gearbox, Adapted From Dirt Bike
CHASSIS: Full-Size, Front Brakes Required
MINIMUM WEIGHT: 395lbs
TIRES: LeCont White, 4.60 Front, 7.10 Rear
RULES: TaG USA
Typically powered by an adapted Honda CR125 (though we do see Yamaha and Kawasaki engines) Stock Motos are the most popular shifter karts coast to coast. They are powerful, fast, reliable and surprisingly low maintenance. Also contributing to their popularity is that they are featured in the biggest kart race in the country, the SKUSA SuperNationals, every November in Las Vegas.
KART SPOTTING TIP: To spot shifter karts from TaGs look for the shift lever to the right of the steering wheel and listen for the gear changes. The exhaust pipe on the Stock Moto Shifters comes out the front of the engine, then goes straight out the back.

KZ2 Shifter
AGE: 15+ Years Old
TOP SPEED: 100+ MPH
ENGINE: Various 125cc 2-Strokes with a 6-Speed Manual Gearbox
CHASSIS: Full-Size, Front Brakes Required
MINIMUM WEIGHT: 385lbs
TIRES: LeCont White, 4.60 Front, 7.10 Rear
RULES: TaG USA
KZ shifter engines are purpose-build for karts, and are the ultimate thrill ride in kart sprint racing! The shifter engine of choice in Europe, they deliver big-time speed and power, plus the coordination challenge of shifting, braking and turning all at the same time while maintaining maximum momentum and revs. In the Northeast, KZ racing has enjoyed a resurgence within the F-Series regional championship, which boasts the largest fields in the US. Come to an NHKA race to chat with our shifter racers, many of whom also run that series too.
KART SPOTTING TIP: The KZ’s exhaust pipe has two parts connected by a skinny curved pipe. It’s mounted down low between the seat and the rear bumper.
