1970 BSA Royal Star A50
Here is your chance. If you don’t have a motorcycles, but want to join the afflicted owners of Classic Motorcycles, this 1970 BSA A10 Royal Star may be the best place to start. As many people who own Classic Motorcycles will tell you, there are good ways to get acquainted with older motorcycles, and there are BAD way to develop your love/hate relationship. Looking at the condition, and the design of this Royal Star, I think this could be the perfect place to start a life long problem.
From the seller.
This is a very solid A50.Compression is 120 on both sides and it does not smoke. Most of the chrome is real good except for one section of the rear wheel and the left headlight ear. There is also one small dent in the chrome portion of the tank. The rest is good to excellent. Other than the tank and side cover paint, the bars and mufflers, it is mostly original .The carb is new as is the chain. The A50 is smoother than the 650 but has of course less power. It is easy to kick over to start. It has an excellent sound to the exhaust and is very pleasant to ride. As the English say it is well sorted .Tires are ok. If you are in the area I would encourage you to look at it and ride it. If you buy it and you pick it up and it is not as represented don’t buy it. This would be a great first classic bike for someone. As always, however, this is a 42 year old used British bike.
First offered in 1962, the Royal Star was BSA introduction into Unit Construction (engine and transmission connected as one unit). The 500cc A50 was an evolution of the A10 offered as a Pre-Unit 500cc bike. The under square 50x75cc parallel twin of the A50 would give you good torque, but will have less vibration then the bigger and more powerful A65 650 BSA’s. With the 9.0: CR pistons that were added in 1964, the Royal Star has 33bhp at 5800rpm, good for a top speed of 90mph. Currently this bike looks like it would have come to the US from Britain, with high bars and a big tank. After the new owner becomes acquainted with their new Classic, it is a good platform for transformation into a Classic British Rockers ride.
The reason that I think that this is a good starter Classic bike is its condition, and the fact that it was designed to be what it is, a 500cc motorcycle for the masses. It is not a high strung stallion, but it is not a small put-put moped. A single Amal Monoblock, later replaced by a Consentric carburetor, gives easy starting; good idle, and ease of tuning. The drive side of the crankshaft was given ball bearings, replacing bushings to improve bottom end longevity. If you are new to kick starting, or motorcycles in general, the design of the 1970 BSA A10 will allow you to learn what it is to own a Classic British Motorcycle. Much better then getting a box of British parts, and trying to put them together. (Ask me how I know)BB
