White & Poppe Two-stroke 1922
White & Poppe four-stroke engines were in the front rank in the early days. The name now re-enters the motor cycle field, gracing a two-stroke engine which is giving remarkable results, almost unbelievable rates of revolution and a degree of silence not usually associated with units of its type. The machine in which it is shown is obviously merely a testing assembly.
