Answer: Powersports: Wiseco Powersports pistons are designed for optimal piston to wall clearance for the specific bore size of your engine. For example, your 125cc dirt bike engine is 54mm bore, the Wiseco piston is designed just for that bore size, and does not require any specific adjustments to fit properly.

Wiseco forged pistons start as raw bar stock in certified 2618 or 4032 aluminum alloy. Once they're cut into precisely-sized 'pucks' they're ready to be preheated in preparation for forging.

Mentor, Ohio All Wiseco pistons are forged and manufactured in Mentor, Ohio.

Wiseco pistons are among the finest powersports pistons available. Unlike most OEM or other aftermarket pistons, Wiseco pistons are forged in-house at their own manufacturing facility.

Flat-top pistons have the smallest amount of surface space; this enables them to create the most force. This type of piston is ideal for creating efficient combustion.

Forged pistons are the strongest on the market. The manufacturing process is different from a cast piston, because the aluminum is not molten like that of a cast piston.

The 2618 alloy is renowned for its excellent high-temperature strength. This makes it the preferred choice for outright racing – especially in extended wide-open-throttle competition. It can also be a superb choice for a serious street power application.

Wiseco forged pistons are built with greater precision and to finer tolerances to withstand more abuse, and deliver an extra performance edge that can make the difference between finishing first or second in a race.

WISECO PISTONS High quality forged pistons is what has made Wiseco World famous in the racing piston industry, since the 1940's. From Off Road and Motocross to Road Racing and Sport Bike, Wiseco is a top choice for enthusiasts and racers alike.

Aluminium alloys are the preferred material for pistons both in gasoline and diesel engines due to their specific characteristics: low density, high thermal conductivity, simple net-shape fabrication techniques (casting and forging), easy machinability, high reliability and very good recycling characteristics.

From a price standpoint, the cast piston is going to be cheaper and lighter, but it won't be as strong. The forged piston will be heavier, but it will be stronger and is typically the piston of choice for big-horsepower, boosted, and high-RPM applications.
