M-series

Animal

Building off of the proven success of the Animal engine, the M-series is the first dedicated racing engine engineered to meet the needs of the Quarter Midget market.  Right out-of-the-box, the M-series is focused on the consistency, and simplicity that racers deserve.  Each engine is hand-built and tested in our skunk-works in Milwaukee, Wisconsin with the craftsmanship and quality we stand behind.
