CP Pistons

After two years of development, CP has expanded its X-forging technology from its custom racing piston program and introduced Project X Pistons: Off-the-shelf fully boxed pistons for a variety of street bike and
Powersports applications including Honda, Yamaha, Suzuki, Kawasaki, KTM and others. CP Piston’s fully boxed forgings are designed to minimize friction and reduce weight without compromising piston strength. CP adjusts the weight balance between the high and low areas of the piston during the forging process, and incorporates bracing and ribs for near unbeatable strength. The inherent design of CP Piston’s X forgings allow for the use of a shorter pin, which increases strength and overall lightness of the assembly.

Project X pistons are identified by the part number beginning with MX. Standard forged piston part numbers begin with M.

PROJECT X PISTON LINE FEATURES:
• Leading edge racing piston technology available off-the-shelf
• Fully boxed-style forging for ultimate strength, durability and power
• Reconfigured piston skirt designs maximize power and reduce
piston rocking
• Coated skirts limit the amount of friction on the skirt/acts as buffer
between piston and cylinder wall
• Double-pin oilers engineered in conjunction with broached oilers
to deliver twice the amount of oil to the pin
• Internal windows allow additional oil to flow to pin
• Wrist pins treated with proprietary coating to eliminate pin galling
and overcome brittleness associated with hardened metals

As with everything at CP, these pistons have been thoroughly developed and tested in extreme applications. The result is a state of the art piston using the latest in technology that was once only offered to the higher
echelons of motorsports. All Project X pistons are available off the shelf and are listed throughout the catalog for your application.

A- External bracing minimizes piston deformation to maintain maximum ring support to deliver more power. B- Internal bracing strengthens the part in the most critical area: the pin bore. This bracing maximizes durability while decreasing friction in the pin assembly. C- Internal windows allow excess oil to reach the wrist pin. These windows along with CP standard double pin oilers promote longer life and more useable horsepower. D- Wider skirt faces and redesigned profiles are engineered for stability, power and durability. All Project “X” pistons come standard with skirt coating which reduces friction, which in turn
reduces heat. (Coating not shown)
