Post Sale Update: This Leader sold for the BIN of $8,500.
Never imported to the US, the Ariel Leader was quite unique with the enclosed design. It was introduced in 1958 but production ended when the Ariel went out of business in 1965.
The 249cc two-stroke twin produced 16 horsepower, enough to get this bike up to 68 miles per hour while pushing that giant fender/windshield combination through the air. The entire package weighed about 330 pounds dry. Interesting design features include an underseat fuel tank (the dummy fuel tank was used for storage and could fit a helmet like the new Honda NC700X) as well as optional hard luggage. Speaking of options, this was apparently the first British bike to offer turn signals.
This example has 13,423 miles and everything is claimed to work except for the clock. It comes with the original owners manual and a copy of the shop manual. Find this leader for sale in Ocala, Florida with bidding up to $565 and the reserve not yet met or a BIN of $8,500
