1975 Norton Commando 850
Up for auction is a legendary piece of British motorcycling history: a 1975 Norton Commando 850 in the desirable and collectible John Player livery. Benefitting from the revolutionary "Isolastic" frame and the more powerful 829cc engine, this Commando runs and rides precisely as it should. Complete with a clean title in the owner's name, this is your chance to own the definitive classic bike that perfected the parallel-twin experience.
The Legend of the Commando 850
Born from a need to compete with a rising tide of sophisticated Japanese motorcycles, the Norton Commando was a game-changer. Its masterstroke was the "Isolastic" frame, an innovative design that isolated the engine and gearbox from the frame using rubber mounts. This drastically reduced the vibration that plagued powerful British twins, offering riders unprecedented comfort and superior handling. The Commando quickly became a legend for its unique blend of brute force and refined road manners.
By 1973, the model evolved into the Commando 850. The enlarged 829cc engine wasn't just bigger; it was better, offering more torque and a smoother, more reliable power delivery. The 850 is widely regarded as the pinnacle of the Commando line, representing the most developed and desirable version of this iconic machine. It’s a motorcycle that delivers a visceral, soul-stirring riding experience that modern bikes simply cannot replicate.

Comments
The two major modifications made to the 1975 Commando were left side gear shifting and the electric start which is sometimes referred to as the “starter assist”. Is the electric start working?
Yes, it has electric start and yes it works. It is a left side shift.
