YAMAHA YZF 400 1998-1999 WRF 400 1998-2002 GRADE A 91.93mm STANDARD COMPRESSION 12.5:1
Vertex pistons are forged from 2618 aluminum alloy to handle the high pressures of modern four-stroke engines. They feature a Molybdenum Disulphide (MOS2) coating on the piston skirt for easier break-in and reduced wear. Vertex offers unique piston profiles and compression ratios in A, B, C, and D sizes. This sizing variation, measuring 0.004 inches, allows for a perfect fit to the cylinder, maximizing power and performance while reducing blow-by and oil consumption. This specific piston has a bore of 91.93mm and a 12.5:1 compression ratio.
