Featuring a sleek black design and banana style shape, the 2-Stroke Black Expansion Chamber is not just stylish but built for speed. Engineered to enhance engine function, the expansion chamber uses volumetric efficiency to promote optimal engine output. The result is an engine that not only goes faster but improves the way the cylinder fills for the next cycle. So whether you are looking to go faster or improve your engine's compression, the 2-Stroke Black Expansion Chamber has you covered.

The Expansion Chamber enhances a 2-stroke engine's power output by expanding the volumetric efficiency. It also provides a boost in the top end speed as well as improving the use of the leftover energy from the burnt exhaust exiting the cylinder. This helps aid the filling of the cylinder for the next cycle.
