Briggs & Stratton

World Formula

The World Formula is a complete 4-cycle engine package based on the popular Animal Racing engine. With an optional push-button start, it is a great low-cost, low-maintenance way to go racing.


WF is a perfect stepping stone for indoors racers. There’s the thrill of better than twice the power and the chance to learn kart ownership basics. Costing about a third of a 2-stroke, it is easy to drive and tune, freeing racers to focus on driving technique, chassis tuning and fun.


“It’s a hoot!” says CFM driver Keith Buffo. “For a simple day of racing fun the World Formula is great!”

CFMotorsports Rotax FR125 SeniorMAX
 

Rotax to the MAX!

The Rotax FR125 MAX is the original push-button start engine for TaG (touch and go), the world’s fastest growing form of karting. Rotax engines are remarkably reliable and easy to maintain. They’ll run 50 hours between full rebuilds (one very busy season), which is unheard of in 2-stroke racing.


With this popular package you have your choice of tracks to run at in the Northeast and beyond, including CFMotorsports’ home track New Hampshire Motor Speedway with the NHKA Racing Series.


There’s also the Rotax MaxChallenge series, where everyone’s engines are sealed and verified to be equal, so drivers compete with skill not bank accounts. There are classes for any age. You can race locally, regionally, nationally, even try to qualify for the World Grand Finals. It’s up to you.


Another Rotax advantage is their unique evolution concept where a single engine can be adapted for every stage of a karter’s career – from the youngest MicroMax kid to a 32+year old Masters racer. The same engine. Buy one and you’re done.
