“Eye Candy” – 1958 Ariel Square Four Custom

In Custom, England by AbhiLeave a Comment

Built in California in 2001, this custom chopper is called “Eye Candy” and it features a motor typically not seen in these kinds of builds – an Ariel Square Four!

The engine design goes all the way back to 1931, soon after Edward Turner designed an interesting new four-cylinder motorcycle engine formed from two OHC parallel twins. The design became known as the square four engine, and lent its name to this Ariel motorcycle. By 1953, the Ariel Square Four had already gone through a few revisions and was formally known as the Mark II. The Mark II featured a 997 cc engine with upgrades including separate barrels, a new cylinder head, and four exhaust pipes, which bumped up horsepower to 40. This enabled the Square Four to ‘do the ton’, even with a curb weight of 425 pounds. Production stopped in 1959.

The seller of this example doesn’t have much to say besides a comment that it’s got a Lockhart oil cooler. Find this Ariel for sale in Garden City, Michigan for $15,500 here on Facebook Marketplace.
