What is Mini Thunder?

Mini Thunder is a safe, organized and controlled environment of amateur racing with it’s aim to provide knowledge and skills about motocross to people of all ages.

It was established in 2003 as a pit bike series and later grew to what it is today.  What we realized is there was nowhere for young riders to learn how to race properly in a safe manner. So we redesigned our pit bike series into what we refer to as a “stepping stone” into the world of racing motocross.  Now Mini Thunder is recognized as one of the largest young rider development series in Canada.

We at Mini Thunder are proud to begin the path of tomorrow’s motocross and supercross stars.

Welcome back to another year of unforgettable Mini Thunder racing.
