Two 6.4″ long Carrillo rods for standard 89mm stroke (6.57″ length for 80.4mm short strokes are special order). For JS pistons only.

Special lightweight, low vibration design has more efficient longer length for either 89mm stroke or 80.4mm short stroke. Because of their longer length, they must be paired with our lightweight pistons, and must use .708″ DLC coated pins in the bushless small ends. The complete kit drops right in and uses regular shell bearings. Contact us for pricing and availability of short stroke 6.57″ length rods for 80.4mm stroke racing cranks.  These are the lightest and highest quality steel rods you can buy for your Norton (more info).  See our recommended Ultralight rods for solid frame 750 and Atlas street bikes.
