The 250 TF was the first machine in a long line which began in 1949. Its main characteristic, its twin cylinder engine with a common cylinder head, theoretically avoids the mixing of fresh gas and burnt gas. The intake is in the rear cylinder and the exhaust in the front cylinder.
The paintwork was ivory-beige from 1948 to 1951 and black from 1952.From 1951 to 1954 there was also the similar yellow – later red – 250 TFS with two carburettors and around 15 hp. Only 400 pieces of this type were made.This Puch has been restored with care some years ago and runs fine.

The posterior bore includes the transfers and the anterior bore, the exhaust and intake ports. High thermal stresses, large moving masses and larger friction surfaces have caused this type of motor to be abandoned in favor of simpler systems, valves, rotary distributors, etc.
