Want to know about Rotax?

Start HERE

Anyone who gets into karting, whether it's a parent with a young driver or an adult starting out on their own, eventually asks the same two questions: what is this really going to cost, and will I be able to keep up?


This page walks you through both, from finding your class to your first race and beyond. There's a clear path ahead for any driver willing to put in the work.

MAX Engines

FIND YOUR CLASS

Since the 125 MAX debuted in 1997, it's been built around a simple idea: drivers should spend their time on the track, not working on the engine. Every 125 MAX engine is CIK-FIA approved, and each class is matched to an age, so finding your starting point takes seconds. Look for your age below, from first-time 8-year-olds to Masters drivers 32 and up.

WHAT WILL IT COST?

Grow Your Driver, Not Your Budget


Upgrade your Rotax MAX as you move through the classes and avoid the cost of purchasing a completely new engine package.


Moving up means an upgrade kit, not a new engine. Each step changes a small set of parts, and a Rotax service center does the work.


An upgraded engine is not a compromise. It runs against the engines bought new for the class and stays competitive.

YOUR FIRST RACE

3 Steps to the Grid

Start with a Rotax dealer or service center near you. They can help you choose a kart and engine and tell you where people race locally.


 

Then pick an event, from club and regional races up to the flagship RMC events.


From there, the path runs all the way to the RMC Grand Finals, where drivers race for Team USA.
