Truggy Ready!

O.S.  25XZ truggy engine

This new engine from O.S. was designed with truggy racing in mind and is ROAR legal. Since it sits in between a .21 and .28 engine, you’ll get an engine that gives you more than enough power for your truggy and great fuel efficiency while doing so. Some of its features include ABC construction, a 3-needle slide carb and a 10-fin, two-piece turbo cooling head.
