Heavy Duty Electric Starter Motor for Norton Commando
New replacement motor for the original Prestolite/Norton Starter
- Four brush, high driving torque motor
- Ball bearings for efficient/easy spinning
- O-ring sealed motor for gas and water exclusion
- Nine-tooth pinion provides a 15.78 gear reduction ratio for an 11% improvement in torque over the ten-tooth stock, prestolite with 14.2 gear reduction ratio
- Spins the engine with VIGOR! Very noticeable/significant increase in cranking speed
- Net weight 2.16 kg, Approximately 2 pounds lighter than stock unit
- A bolt-on interchange...NO MODS REQUIRED!
- We highly recommend changing your current starter cable to the heavy-duty 6 gauge cable kit (part number 06-5909/10/11/L)
- If you are using a Boyer ignition system on your Norton, we have found electric starters draw too much current for the Boyer to work properly. We would recommend changing back to a points system, or a DIGITAL electronic ignition system like a Tri-Spark or Pazon electronic ignition system. The Lucas RITA system will work, but is no longer manufactured.
- If you have preexisting problems or defects with your starter mechanism, a new starter motor will only make these issues more apparent.

Product QuestionsQuestion by: Graham on Mar 26, 2018 6:19:00 PMI'm sorry it took so long to get back to you, but we needed to touch base with the manufacturer first. This is a direct quote from an email the manufacturer sent us:
" A MKIII commando starter wire comes from the starter solenoid output wire. Battery power goes to the solenoid input. The battery ground goes to the rear engine stud. Battery polarity does not matter. the starter wires do not get touched at all."
So you will be fine with a negative earth system using this starter.Answer by: rick c (Admin) on Mar 29, 2018 4:40:00 PMDo you need to open the primary case to install this starter motorP
Also is this motor the same as the Dyno Dave starter I have been hearing about?Question by: marshall dawson on May 23, 2018 5:02:00 PMI have not replaced an electric starter on a Norton, but I believe you do have to remove the primary cover to replace the starter. We sell what is commonly known as the "Dyno Dave" starter. We believe it's the best replacement starter available.Answer by: rick c (Admin) on May 24, 2018 9:46:00 AM
