As often happens the work on this bike started at rebuilding the front wheel and moved on from there

Ariel had been best known for its four-stroke singles, twins, and the unique Square Four. But after exhaustive market research, the company decided it was time to change direction, so in July 1958 after a combination of several new technologies for Ariel, primarily the use of a 250-cc two stroke engines, pressed-steel frame, and odd-looking trailing-link front forks, the Ariel Leader was introduced to the market place.

The enclosed styling allowed for a chassis structure that stored fuel beneath the seat, while the "tank" served as a convenient storage area.

Another interesting aspect of the Leader was the long list of options available. As a result, few of the 22,000 produced were exactly the same. Colour choices included Oriental Blue or Cherry Red with Admiral Grey accents, sports, the optional side bags and rear luggage rack.

By 1959, Ariel had put all its cards into the Leader, having dropped the Square Four that year.

A cheaper, stripped down Arrow model followed, as did a Golden Arrow "sport" version.

But the deck was stacked against it by this time, as Japanese imports flooded the market, and Ariel folded its hand in 1965.

After the wheel building the bike would not run properly.

Investigation found the problem to be rust in the fuel tank, often overlooked when refurbishing all the paint work, which was very well done by the owner, but did not realise that the tank inner was rusty.

The bike will now run, and hopefully my customer has learnt that outside paint may make things look fantastic, but rust gets everywhere!
