Tomos Parts

February 28, 2015

Welcome. ManTomos Logoy Tomos parts are in the Parts By Type sections. Below is a summary list of Tomos parts with links to the Parts by Type sections. The parts are described by sizes, specs, and type rather than part numbers and brand names. This system allows for when the same part is used on several different brands. For example, “Tomos A3 rings” are also “Sachs rings” and “Puch rings”. Instead, here we call those rings “38.0 x 2.0 FG”. That is more technical, but more universal and correct.

This Flag 1list is of United States model Tomos mopeds and nopeds. Tomos began in the US in 1976, but their new A3 moped came out in 1974 in Europe. Before that Tomos made Puchs, under license. 2013 was the last year Tomos sold new USA mopeds. That is why the dates below all range from 1974 to 2013.

Engine Names (all are under two horsepower, two speed automatic with pedals, some with kick start):
“A3”   was 1974-1991
“Top end” is cast iron cylinder with piston controlled intake, two transfer ports, aluminum head.
“A35” was 1992-2006

“Bottom end” has wider gears and clutches, bigger roller clutch, more solid cases.
“A55” was 2002-2013
