A LITTLE HISTORY

In 1996, Rotax (Austria) established a department whose responsibility was to research the international race kart market. What they found was an opportunity to develop a product targeted to the leisure racer, "Recreational Racer.” Rotax established its Kart Engine division, whose philosophy was to develop a range of kart racing products targeted at the recreational race enthusiast. Rotax's main goal was to design a new power plant with features not found in traditional kart racing. Most important to Rotax was to keep it affordable and reliable with low maintenance needs. In 1997, the innovative ROTAX MAX engine was created along with the spec kart racing class program.

In 2000, Rotax made its way to the United States. The ROTAX MAX program became controlled by authorized distributors in the U.S. and as a national competition. All engines racing in the series are sealed, allowing for no modifications. As a result, this keeps costs down and ensures a level playing field—letting driver skill pave the way towards victory. With demographics ranging three generations the series targets a wide array of people: young, old, families and individuals.

Quick Fact: Rotax is the fastest-growing kart racing class in the world – competing in over 100 countries.


GETTING STARTED

Whether your goal is to compete at the highest level or enjoy a weekend of racing with friends, the Rotax Kart Challenge is for you. It all starts at the local level and through a feeder system of local, regional, national and world championships, participants get the opportunity to test their skills against the best pilots in the world.

The series is based around the ROTAX MAX kart engine. There are five classes, satisfying ages 8 to 80, and four of the five classes utilize the same FR-125cc engine. The newest class uses the revolutionary two-speed DD2 engine and races in a class all by itself. As mentioned earlier, all engines racing in the series are sealed, allowing for no modifications.

ROTAX MAX is more than just a karting class based around a spec engine; it is the embodiment of a return to the art of racing. In a sport that has always been a combination of science and art, these sealed engines have minimized the role of science by combining maximum performance with 50 hours of running time backed by a six month warranty. Support this technology with a worldwide program of regional, national and world championships, and you have The ROTAX MAX Challenge.

A key factor for the success of ROTAX MAX is strict control over engine specifications. The engines are sealed by an 'Authorized ROTAX distributor' or their 'Authorized ROTAX Service Centers,' and they are the only ones allowed to check, service and reseal the engines. The chassis type is sanctioned by the ROTAX distributor and/or ROTAX Kart Center. Furthermore, the only tires allowed are MOJOs (developed specifically for the ROTAX MAX Challenge).

TIPS TO GET STARTED

A few tips to help you get started in Rotax Max Challenge:

1. If you do not have your Rotax kart and gear yet, visit a dealer near you.

2. Check our listings, ask your dealer or search the web for a local karting track racing school. This is the best environment to learn and practice the fundamentals of racing and build your confidence behind the wheel. We recommend a four hour (half day) school to get started.

3. Apply for your Rotax Membership by CLICKING HERE. In addition to your license to race, we will send you some valuable technical information about your kart such as rules that apply to the R-Max Challenge Race Series and some stickers. Most important, we will keep you in the loop about national events.

4. Find a scheduled R-Max Challenge Race in your area. Attend the event as a spectator, but do not hesitate to introduce yourself to the other Rotax drivers. Most important, ask questions. Remember, they were new to the sport once upon a time too.

5. Attend a lapping day at your local track with a friend or family member who can lend a hand. In between sessions, observe how others drive the track. Pick out the fast karts by timing them, and then apply what you have learned to your driving. Try to partner with other Rotax drivers so you can compare notes.

6. Go Racing! Show up early and familiarize yourself with the schedule of events for the day or weekend. Make sure your equipment is in order, and take the time to go through pre-tech.
