Kart Engines – Rotax

Rotax MAX Engine Concept

Rotax Engines have a long history of quality and ease of use. The FR125 karting engine is no different. All engines come
with an electric starter package.

 

The evolution of the Rotax concept is from the fastest engine package (the DD2, 2-speed) to the most entry level package,
the MicroMax, designed for ages 8-10 years old.

 

The evolution utilizes the basis of the FR125 in various trim packages so that it is conceivable to start in MicroMax and
keep your same engine throughout your karting career. How is that for cost-effective? In addition, the sealed-engine
concept and engine passport system keeps a level playing field while providing you a service log of each engine you own
or compete against. A complete engine service history means you have an engine that will retain its value over the years.

 

Here is a look at the engines available with specifications and don’t forget to GO Rotax!
