Briggs & Stratton LO206 Engines Available for 120 Classes

The idea behind these new classes is ONE common engine that will fit all 4 brands of sleds. This provides a true fair and equal "crate" engine class, with no modifications allowed to the basic engine package that is factory sealed by Briggs & Stratton. Simply put, if the seals are cut, the engine is illegal.

4 Cycle Central has everything you need for your LO206 sled, from engines to exhaust to mounting brackets to complete kits. Check our LO206 products page for more information.
