For use with all models.  Requires the use of a 4 5/8" stroke crankshaft. Package includes new cylinders.  Case boring is required.
 
The owners (Kevin and Doug)  use these motors in a Dyna Superglide and a FatBoy. Many of our customers are using this motor in their FLH bagger type touring bikes because of the incredibly low rpm torque and dependability.  The increased stroke provides a better mechanical advantage through rod leverage and the results are much higher torque figures at a lower RPM. Mellow 2,000 RPM cruising is possible with plenty of power on tap for explosive throttle response through the whole mid-range and upper end.
