Wiseco Bottom End Rebuild Kit for 2001-04 Yamaha YZ125 - WPC125
Wiseco Performance Bottom End Rebuild Kit
- Wiseco now provides an all in one kit for your bottom end
- Made with the toughest materials for increased performance and life span
- Includes the Crankshaft Assembly, Main Bearings and Bottom End Gasket Kit
Wiseco Crankshafts are 4340 steel, core hardened and tempered to reduce stress and optimize tensile strength. The crankshafts are made with a nitriding process for hardening rather than induction heat treated. This eliminates any softening between the journals and any post running deformation. Our crankshafts also feature straight oil holes for the best oiling to the rod journals to insure you get the best crank for your money. Each K1 crankshaft is magnetic particle inspected and held to a maximum tolerance of .0002” journal dimension. Counterweights are placed for optimal load reduction and ease of balancing making less work for you or your builder.
