I've decided to sell my 1975 Norton Commando MK3. This bike came out of a garage in Minnesota. The story passed along to me from the original owner was that he was a farmer who only rode the bike during the short riding season, in between his farming duties. The mileage shown on the odometer is just under 2,000. The trip odometer doesn't work, but the odometer does. I can't claim that the miles are accurate, but the bike does not show any signs of ever being apart. All of the fasteners are original to the bike, including the timing cover and primary cover screws, which are usually swapped for allen head bolts after the originals have all been stripped out. I've owned many MK3 Nortons, and have restored many as well, and this bike, apart from the Dyno Dave starter, and mufflers, is all original. The airbox has been removed, but is included in the sale, along with the original starter, and right hand control switch. The original Lucas switch failed, and was replaced by a Sparx unit. Everything works as it should, and works very well. The bike is in excellent tune. It starts VERY easily from cold, with only a little choke needed. It settles into a very smooth idle, no smoke, no funny noises. Going down the road, the bike has great manners. The acceleration is instant and comes on very easily. It shifts very smoothly and deliberately, despite the clunky shift mechanism given to these bikes in 1975. The brakes are surprisingly ample, with the rear brake working better than any MK3 Norton I've ever had! The original chrome brake discs are still with the bike. The swing arm does not move around, and the rear isolastics still hold the cradle to the frame tightly. The overall finishes of the bike are consistent with its age. The rims have some flaking chrome, as does the kick start lever. The paint on the tank is crazed, and thin in areas. The steel side covers have been repainted at some point. Very well done too. As seen in the pictures, there is a golf ball sized dent on the left side. The bike fell over at some point in its life. Please ask any questions along the way.
