Carrillo MX1P27-P Platinum Series Racing Piston 95mm 14:1 Yamaha YFZ450R

The Carrillo MX1P27-P Platinum Series Piston is a premium racing piston engineered specifically for 2009-2019 Yamaha YFZ450R ATVs. This high-performance forged piston features a 95mm bore diameter and an aggressive 14.0:1 compression ratio, making it ideal for serious motorsports competition and maximum power output.

Advanced Racing Technology:

• Ceramic crown coating reflects heat into the combustion chamber while lowering piston temperatures for increased durability and improved combustion performance
• Profiled pin bore machining reduces stress in critical areas and allows the pin to flex naturally, significantly increasing component life
• Tapered wall 9310 DLC (Diamond-Like Carbon) coated wrist pin provides superior strength while reducing friction and weight
• Short piston skirt design with CT-3 skirt coating minimizes friction and reduces overall weight
• Boxed X-forging construction delivers exceptional strength-to-weight ratio

Performance Features:

• Double pin oilers ensure proper lubrication under extreme conditions
• Accumulator groove optimizes oil distribution
• Anti-detonation grooves enhance reliability at high compression ratios
• Full radius dome design maximizes combustion efficiency
• Weighs 10 grams less than non-race version for reduced reciprocating mass
• New cam and barrel profile for enhanced durability and power

Important: This Platinum Series piston is designed exclusively for use with CP-Carrillo Platinum 3.5mm longer connecting rod kit (not included). The extended rod length and smaller 1mm wrist pin are engineered to work together for optimal performance. Requires 110+ octane race fuel due to the high 14:1 compression ratio.

Developed and tested by professional racing teams including Wienen Motorsports and trusted by winners of MX and GNCC racing series worldwide. Manufactured by CP-Carrillo, part of the Pankl Racing System Group, at their facility in Irvine, California, USA.
