Norton Commando description

Up for sale is a 1975 Norton Commando MKIII that has had a very comprehensive restoration. 
I'll start at the beginning of the story: I heard about this particular bike sitting in someones garage in the high desert in California. The last time it had been on the road was 1980, as per the story, and the last registration date on the blue California license plate which is original to the bike. I made contact with the owner, who purchased the bike in 1978. He was very coy and aloof about selling the bike, or much less, giving any information on it. Over the course of about 9 months, I started breaking down his defenses, and learned to speak his "language".  He became much more informative and forthcoming with the story of the bike and actually sent me some pictures, via our smart phones, of the state the Norton was in. He explained that it had been in a low speed lay down.  He explained that the gear box had locked up. I had assumed it was the failed Portuguese layshaft bearing that had failed and pitched him off of the bike. The collateral damage was limited to a broken speedometer, bent left foot peg, and, of course the gearbox internals. After dusting off his wounded pride, the bike was put in his garage for the next 35 years where it would sit and collect dust. 
In a deal that was struck in mere seconds after our last phone call, I raced down with my truck and trailer and excavated this bike out of his garage and laid the cash down on his desk before he could change his mind. I unloaded at my shop a few hours later and surveyed the project. I've certainly restored Nortons in much worse shape. This bike was a 12,000 mile example. A complete, but dusty time capsule that had some 1970s era bolt on goodies. The engine had good compression, but the gearbox, as stated, had its issues. So, the tear down begins. This was not my first MKIII restoration. I am very comfortable with these machines and have owned my share and will continue to buy and restore them. But being the consummate tinkerer that I am, I need to start another project. To see more pictures of the build, see my Instagram at norton_guy. You'll understand my disease.

So, what have I done??

  • New (Sparx) right and left switches
  • Lucas headlamp and tail lamp
  • Re manufactured Speedometer and Tachometer from Vintage British Cables from Canada. (Great folks to deal with)
This should be a good list to reference the restoration by. There are plenty more little things that I have done to ensure this to be one of the nicest Nortons around. Please ask any questions you may have. 
As far as a title is concerned, the seller lost it years ago. I have had the bike inspected by the California Highway Patrol. All paperwork is in order to take straight to the DMV for a title. There are no liens, etc. This was a clear titled bike in 1980 when parked. Please bid within your comfort level. This is NOT a "quick flip" or "rattle can" restoration. Many hundreds of hours and many thousands of dollars were put into this bike. Please respect that and bid accordingly. I can store the bike for an agreed amount of time after the auction. Bike must be paid in full first before storage arrangements are made. I will help any shipper on my end with getting the bike to you, but the cost is up to the buyer. I will accept cash in person, or a bank wire transfer. The bike will not be released until funds are verified.


On Jul-04-16 at 02:00:25 PDT, seller added the following information:

To answer a couple of questions--and I may have been hasty when writing the description--Sorry!  The mileage on the new odometer is correct. At the time the pictures were taken, only 25 break-in miles have been put on the bike. I think that number has increased to about 30 miles. I have adjusted the valves 2 times, and have re torqued the cylinder head 2 times as well. For good measure, or over-kill, I have changed the engine oil at both of those service intervals. I installed a genuine Norton oil filter and have used Valvoline 20-50 racing oil for its zinc content.

Also, I forgot to mention in the Chassis section of the description, I installed the Dave Taylor head steady and retained the spring as used on the stock MKIII units. And, that is a Colorado Norton Works chain guard that Brent Budgor painted for me.

The first Norton to roll off the assembly line in 2021 will be Commando

Wed, 23 Dec 2020

The British company plans to produce 40 motorcycles of this model, most of which have already been prepaid. And only after the end of the story with Commando, the company will move on to the assembly of the V4 model, and then the two long-awaited Atlases. According to the company's management, the new model, Norton Atlas, currently still requires a number of final fine-tuning works before the start of mass production.
