• Fits KX65 2003-2010 and RM65 2003-2005 models.
• The Factory Fatty, factory equipment for the general public.
• Constructed with two different thicknesses of US steel, 19 gauge for the header portion for optimum strength and durability, and thinner 20 gauge for the body and rear cone section for increased weight savings.
• The thinner steel also yields a slight increase in power (up to .5 hp) due to more efficient wave resonance.
• All seams are hand pounded after the stamping process to give it a smoother transition between sections and a factory look.
• This pipe comes with a raw, unplated, oiled finish.
• Bolting on a Factory Fatty will enhance the powerband throughout the range. With increased horsepower and torque, you will not be sacrificing power to gain that factory look and feel.
• This is the same pipe many of the top supercross and motocross riders are using today.
• Must be used with FMF Silencer.
• For Kawasaki KX65A4, KX65A5, KX65A6, KX65A6F, KX65A7F, KX65A8F, KX65A9F, KX65A9FA and Suzuki RM65K3, RM65K4 and RM65K5.
