Identification Guide
Most Parilla Motorcycles have a 6 digit serial number, the first 3 digits
are the model number and the last 3 digits are the production numbers.
The frame numbers can be found stamped into the left side of the steering
head, and the engine number can be found stamped into the crankcase near
the top rear mounting lug. Frame and engine numbers should match. Some
competion engines entered the United States with no serial numbers.
