A Must Have

Just put this in my 2009 YZ250F an right after I got the bike back together and running I could tell a huge difference in the power. It almost threw me off the back because I wasn't expecting my bike to accelerate that much faster. The only down side is the higher cost of the gasoline you have to run, but if your serious about racing this is a must have!

Answer: I would recommend contacting your engine builder for octane questions referring to aftermarket performance. High compression pistons can need higher octane dependent on what is all done to the engine.
