Wiseco SK1195 Pro-Lite 2-Stroke Piston Kit 81.00mm for Arctic Cat Snowmobile

The Wiseco SK1195 is a Pro-Lite forged 2-stroke piston kit engineered specifically for Arctic Cat 650 Wildcat and 700 Mountain Cat snowmobile engines. Featuring an 81.00mm (3.189 in.) bore with a 68.00mm stroke and a floating wrist pin design (0.787 in. pin diameter), this kit is built to deliver maximum performance and durability in demanding snocross and cross-country riding conditions.

• CNC-machined cam shape and profile optimized for peak horsepower and extended service life
• Condensed, aligned grain structure delivers superior resistance to impact and fatigue
• Optimized strength-to-weight ratio reduces reciprocating mass for improved throttle response
• Fully engineered, forged, and machined in the USA (Mentor, OH)

Kit Includes:

• Forged Pro-Lite piston(s)
