Thanks for this page option to peaple like me around the world. My Norton Commando 850 Engine No.is 850-334502 and Chassis No.is 94543! I am told that its frame has been changed to the present one. I dont know their year of make. And, what are the differnces between a Roadster,Interstate and Mk 3. My bike is in good condition, gleaming paint,shining chrome and bright lights! It runs very well indeed. Even the so-called´Electric Start´self-starter motor fires the engine on a mere touch! Poor m/s.Lucas dubbed; ´prince of darkness´is proved wrong! Kindly respond to my first ever mail to you. We are still alive and kicking in Pakistan. Its really a good place, not that bad at all, as the international Jewish controlled media weave to build. OOPS! Anti-semitic? Not at all. Thank you. Nasir Khan.
