Harley Davidson 1.7 Kw Chrome Starter Motor 

This 1.7kW motor is a good solution for big-cube or hard-starting motors as long as 4ga battery cables are used to reduce voltage losses, and the battery is at least 300CCA. This design utilizes a permanent-magnet motor coupled to the OE-style offset gear reduction design that generates high output and torque in a small package. The starter is no larger than the H-D 1.2kW unit and fits into all Big Twin applications. The issue with any permanent-magnet motor is that the in-rush currents are higher until the starter armature begins to spin. It is not a good solution for a bar-hop bike because there is a chance the charging system will not keep the battery fully charged.
