1000R Maverick  this is a +1mm bore of the oem 420686094 piston allowing you to re use your factory cylinders with a fresh bore from your local machine shop

This takes your 976 cc 1000R engine to 997 cc

Factory head gaskets work just fine with these pistons no need for special made gaskets

Forged pistons 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.

12:1 CR (Compression Ratio) same as factory

The piston skirts feature ArmorGlide™ Coating this is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance.
