Details
This kit features a 6mm stroked crankshaft with 3mm shorter rods.
This combination results in the same piston deck height as stock so the kit can be fitted as a direct replacement for the stock crankshaft and rods using any size pistons available for the RE Twin.
With stock pistons, displacement is 705cc at 10.3:1 compression.
With S&S 750 kit (83.5mm bore) displacement is 808cc at 11.7:1 compression
With S&S 865 kit (90mm bore) displacement is 939cc at 11.7:1 compression
By default, kits are balanced to 50% for S&S 90mm pistons so they can be used with or without the counterbalance shaft.
