Wiseco Nylon Flexhone Brush 57-70mm - V-Twin Cylinder Finishing Tool
About Wiseco
Wiseco has forged pistons in Mentor, Ohio since 1941, supplying everything from factory race teams to big-bore street builds. Forged construction is what lets a V-twin survive higher compression and more cylinder pressure than the stock cast piston was designed for.
The Wiseco Nylon Flexhone brush for 57-70mm bores is engineered to provide a superior finish in V-twin motorcycle cylinders after initial honing. Its abrasive-impregnated nylon bristles meticulously remove microscopic peaks and scuffs without altering the bore size, preparing the cylinder for ideal ring seating.
