ADR STROKER CRANKSHAFTS

All ADR performance crankshafts are equipped with connecting rods that offer a true chemical composition of 8620 aircraft quality steel which absorb over 12,500 RPM and helps transmit motion balance. These rods are CNC balanced to the gram on the 8mm and 10mm Stroker versions to help reduce vibrations for a smoother running engine. ADR rods were made just for the Yamaha Stroker crankshaft series, the only ones in the world like it and assembled in the USA.
