1974 Norton 850 Commando


Two Owners from New, Original Bill of Sale, Original Tool Pouch and Manual


This 74 Norton Commando 850 Mk. 2A Roadster was sold new in London to a gentleman from Denver, Colorado. We still have the original bill of sale and letter from Elite Motors of London, where he purchased it. He owned it until 2003, when he gave it to his longtime friend, who we purchased it from. The bike also comes with service records dating back to 1975 and up through recent times too. In the late 1990s the bike was mechanically and cosmetically restored by Essex Motorsports in Chester, CT.


The following work was completed:

Disassemble from frame

Disassemble bottom end

Decarbonize head, pistons, valves

Cleaning- all components

Inspection- all components

Hone cylinders and fit new rings

Disassemble crank, clean, fit new rods and inserts

Assemble bottom end

Install into frame

Assemble top end

Finish assembly

Set torques and clearances

Charge battery, connect wiring, set ignition timing

Polish covers- aluminum

Top off fluids

Clean carbs

Fine tuning


Before that, the bike had a $4,000 service while still in the original owner's care. This included:

Remove primary, timing and trans covers, wet sand and polish.

Replace all bearings, bronze bushings, gaskets, seals and kick start pawl. 

Remove fork tubes and overhaul, new springs, seals, clean damper rods, polish sliders

Change all fluids, replace wheel bearings, adjust steering head bearings, top up 140w oil to swingarm

Adjust primary and drive chains

Install new points, clean and lube advance unit, adjust valves and set ignition timing.

Install complete new exhaust system with peashooter mufflers

Overhaul and sync carbs

Reupholster seat

Refinish tank and side covers 

This is a beautiful restored bike that runs and rides as well as it looks. It has a good battery, good tires, perfectly adjusted isolastics, and all signals and lights work. It has just been fully detailed. The only real cosmetic flaw is a small quarter sized bubble in the upper right hand size of the tank just below the pinstripe.
