Here is a really excellent usable example of Ariel's quality big twin - the 650cc Huntmaster.
Basically a BSA A10 engine in an Ariel frame the Huntmaster from this period offers a good handling smooth, beefy and reliable classic ideal for 2 up work and longer distances.
Starter very easily indeed , rides beautifully, excellent gears, clutch brakes etc. Charging well and speedo is working.
This is a really great classic British big twin. Bags of fun to ride and very handsome too.
