JE Pistons Honda TRX450R 13:10:1 94MM Bore Piston Kit

This is a JE Pistons 13.0:1 compression piston kit specifically for the 2004 and 2005 Honda TRX450R. If you're looking to get more power out of your ATV's engine, a higher compression piston like this one can make a notable difference. It works by squeezing the air-fuel mixture more tightly before ignition, which generally leads to a more powerful combustion event.

JE Pistons are well-known for their forged pistons, which are stronger and more durable than cast pistons. This 94mm bore piston is designed to be a direct replacement for your stock piston, though it does require a higher octane fuel to prevent detonation due to the increased compression. The 13.0:1 compression ratio is a popular choice for those seeking a significant power boost without going to extreme measures.

Keep in mind that this piston kit is not CARB approved and cannot be shipped to California. You'll also want to ensure your engine is in good mechanical condition before installation, as a higher compression piston puts more stress on other engine components.
