Wiseco Racer Elite Kolben-Kit Honda Crf450r `17-22 14.0:1 Cr

WISECO Racer Elite  4 Strokes Pistons 100% CNC machined forged piston Dyno test bench proven power increase Reduced friction for improved performances: first and unique asymmetric piston in the market. For 250cc and 450cc applications Precision machined ring grooves with proper orifice/ accumulator volume feature calculated groove root diameters and axial widths, providing excellent surface finish and flatness, maximum ring seal, and minimized blow-by and oil consumption. ArmorGlide™ skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Allows the piston to be fitted tighter within the bore allowing a better ring seal and reduced noise from piston rock. DLC coated pin: F1 technology to offer best friction reduction and wear resistance.   WISECO pistons are made in USA, forged and their design work is very detailed to ensure the latest piston skirt profiles for minimal rock, tight clearances, and long skirt life such not to need centesimal sizing to accommodate cylinder bores. This is WISECO pistons special feature, applied in 75 years of production. WISECO forged pistons benefit of a different thermic dilatation in respect to any other competitor product. WISECO pistons have self-proven over time for best durability vs. performances compromise.   DLC” coated pin Boxed-bridge internal structure ArmorGlide™ low friction skirt coating  Anti-wear surface treatment on piston top and rings seat Increased compression ratio  NITRIDE TITANIUM” rings treatment for improved sealing and reduced blow-by
