Product Description

Important note: This piston is for a stock sized bore. Please measure your cylinder to check clearance before ordering.

Wiseco leads the performance aftermarket by producing the highest quality forged pistons in the U.S.A. Wiseco is unique because they forge all of their own pistons in-house, and produce all of their own forge tooling in the U.S.A. This allows Wiseco to control all aspects of their manufacturing process from raw bar to skirt coating on the finished parts.

Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.

Wiseco Pro-Lite motorcycle pistons are forged using the highest quality materials available resulting in a piston that provides excellent performance and durability. The Wiseco Pro-Lite piston features a race-ready dome finish with smooth edges for improved combustion flow. The rings, wrist pin, and circlips are manufactured by Wiseco under their strict quality standards to make sure every piston kit fits correctly, ensuring top performance is achieved.

I heard somewhere that there used to be or still is A and B piston sizes what do you do when your Cylinder wears out since you cant really bore it out to the next size? sorry im a car mech not a motorcycle mech!!

A & B pistons vary in size by millimeters. You can actually run an A piston in a B cylinder. But you can only get these sizes through OEM. Wiseco pistons can be installed in either an A or B cylinder without any problems. The only way to "bore" a Nikasil cylinder is to get it re-sleeved or bored out and re-Nikasil the walls. To re-sleeve it, it's best to send it to a machine shop or place that specializes in this type of think. A company off the top of my head is LA Sleeve. Look into these guys as they offer a cheap solution in a reasonable time frame.

Should i use a stock or after market piston why does the wisco cost more 2005 crf 450?

It comes down to personal preference. Personally I haven't had any issues with Wiseco pistons so thats what I stick with. As far as cost goes OEM is a cast piston where the Wiseco is a forged piston to help increase the life. Plus being an after market company has a small increase in the price.
