Need Help Deciding Which F100 Class Is For You? Classing Is As Easy As 1-2-3! A Thorough Explanation of F100 Class Names

Classing is as easy as 1 – 2 – 3

1.     F100 currently offers one type of class, Formula, or “F” designated classes. These classes combine many different engine packages into one equal and competitive racing class. The engine packages utilized in these classes depends on the age group, but as an example FK1 Masters combines KPV3, KPV4, Formula Y and KT100 pipe into one class. Please see the class structure for specific information about individual classes.
2.     The second letter is the age indicator. C is for Cadet, ages 8 to 12. J is for Junior, ages 12 to 15. K is for Senior, reminiscent of the old Formula K class. Senior classes are for ages 15+. Within the K classes there are also Masters classes, which are for ages 30+ or drivers 15+ who weigh over 200 lbs with their racing gear on race day.
3.     The first number represents the license level, Level 1 or Level 2. Level 2 classes are for less experienced racers. Level 2 licenses are automatically awarded. Level 2 classes are designed to be as inclusive as possible, while still providing equal competition for all racers. Level 1 classes are for more experienced racers who wish to race with top-level competition. Within Level 1 classes there are also Level 1 Advanced classes. These classes provide some of the best competition anywhere!

Top Level Shifter Kart Racers Test Old School 100cc Direct Drive Power, AND LOVE IT!

Check out this story from Kart360 that discusses the test drive of a mid 1990's Formula A 100cc kart by factory KZ shifter kart racers Jordon Lennox-Lamb, who swept the SKUSA S1 Pro-Tour and won at Supernats this year, and Gary Carlton, who is widely believed to be one of the best, if not the best, kart racers from the United States.  This is a great story, and it really shows the feelings and emotion that the purity of direct drive karting brings out in racers!  My favorite quote is from Gary Carlton, who is a factory racer for TB Kart in Europe:

"It was like nothing I have driven before. The first time I pulled the engine the whole straight was something I will never forget. The sound of the engine revving towards 20,000 RPM gives you goosebumps the first time. It felt so pure. The chassis was so light and quick to respond. A whole different driving style where you can really throw the kart around. It was a great experience and I now can say I know what it was like back in the day, and I will say, they had it way better than we do now."

F100 2015 Tech Update and Reminder


Due to a last minute change in insurance requirements, there have been a few updates to the F100 Rule Supplement:

1) Driver's age ranges for classes are now as follows. Cadet is 8 to 12. Junior is 12 to 15. Senior is 15+. Masters is 30+ or drivers over 200 lbs.

2) Double nutting weight/ballast bolts is legal. However, please see below for more information on ballast. 
3) Helmet mounted cameras are allowed, provided they do not compromise the safety of the helmet.
4) Driver's age is determined by the driver's actual age on December 31st, 2015.

- This age rule means that if the driver turns 13 in 2015 they are too old to race in any FC class. If a driver turns 16 in 2015 they are too old to race in any FJ class. If a driver turns 30 in 2015 they are eligible to race in the Masters class. For those wishing to move up or stay in a class waivers are possible but not guaranteed. Please contact F100 for more information.

F100 would like to remind racers of the new requirements for mounting weight/ballast onto your kart:

All weights must be white (painted, coated or white tape). They must be securely fastened to the kart with at least one lock nut and lock-wire/cotter or they can be secured using two lock nuts. All weight ballast over 7 lbs. must be secured to the kart with 2 (two) bolts.  The bolts must be 5/16" or larger. (8mm bolts are legal.)  All bolts must have either cotter pins, safety wire or use two locknuts to secure the weight to the chassis.

F100 would also like to remind parents to please bring proper documents for their minor racer, including proof of age to the first race of the season that the minor racer participates in.

For racers choosing to utilize the Spec Pump Gas option, please purchase your fuel the morning of the race from the appropriate spec gas station for the Calspeed track:

If you have any questions please email F100 at

F100 Releases 2015 Class Structure, Confirms July Race Date

The Formula 100 Karting Series has released their 2015 Class Structure. The class structure is similar to last year. Changes include a reversal of the licensing levels, with Level 1 now becoming the top level, a more inclusive Masters age class, and the utilization of a faster engine package for the Senior Advanced class.

Level 1 classes, now the top level of F100 competition, in the Senior and Masters age groups, now have more options for racers. FK1 Masters (FK1M) now has options for light (360 lb) and heavy (390 lb) racers with KPV/HPV and KT100 engine packages.

FK1 now has more options as well. FK2 racers will find a home in the FK1 class, which combines the KPV/HPV 3 engine package with the KT100 Formula Y engine package, just the same as in 2014. The FK1 class is the same as last years FK2 class.

For FK3 racers from last season, the second of the FK1 classes, the FK1 Advanced class, is the perfect fit. This class will utilize the faster KPV/HPV 4 and KT100 approved open pipe package, similar to what was used during the California State Championships. As a result, this class will provide a little more speed and quicker lap times as compared to last years Advanced class.

The class structure for Juniors and Cadets is much the same as in 2014, except for the License Ladder change, with Level 1 classes now serving as the highest level of F100 competition. This means, for example, that last years FJ2 class is now known as FJ1, FC2 is now known as FC1. Level 1 classes are now the highest level. Level 2 classes are now the first step in the license ladder. The rest of the class structure for Juniors and Cadets is much the same as last years class structure.

For more information on the class structure, please visit the following link:

F100 has also released a schedule update for the July F100 race (Round #5). For more information, please visit the following link:

National Level 125cc Racer Goes Back to 100cc Racing; Back to Basics

Kart360 featured a great story by national level TaG racer, TJ Koyen. TJ has recently decided to move from TaG racing to Yamaha Supercan, which he calls "one of the greatest racing machines in the world." A Yamaha Supercan is a Yamaha KT100 with a 4 hole can exhaust. This package is raced heavily throughout the Midwest and East Coast of the United States, and F100 allows this package in its Novice level classes for Junior and Senior racers. Check out the following quote from the article:

"After six long seasons of hard work in the national TaG Senior fields with a couple big wins but also big spare parts bills, I’ve inked a lucrative contract to pilot one of the greatest racing machines in the world… A Yamaha Supercan... I know what you’re thinking... Why would you move back ‘down’ the karting ladder to Yamaha?” Mostly correct on all counts reader, but hear me out. TaG isn’t fun. Okay, that’s not completely true, but the class has its negatives. Yes, it’s the fastest single-speed kart class in America right now. Yes, it has incredibly deep fields of talent and massive entry counts in most places. Do you know what else TaG has?: carnage, expense, complication, over-zealous driving."
