1949 Ariel Square 4 Pictures

Add Your Photos!

Very smooth runner. Stripped out rear spark plug threads after purchasing bike. Threads were frozen from excessive heat on rear cylinder. Installed helicoils and kept plugs changed. Surprisingly small motorcycle. Not the best choice for a big guy. Venturi on single carb was maybe 3/4″ (18mm) in diameter and supplied 1000CC. Amazing by todays standards! Only picture I have. Sorry about the poor quality.

Many thanks to Jim Hansen for this picture of his Ariel.
