234 pages and more than 300 illustrations and charts, size 8.25 x 10.75 inches. This manual is a reproduction of the original Floyd Clymer 100cc and 125cc Sachs Engine workshop manual. However, it has been updated with a 1974 illustrated 'List of Spares' for the 100cc and 125cc Sachs engines. In addition, it includes a 1968 illustrated 'Spare Parts List' for the 1968 to 1971 Sachs 'Enduro', 'Cross Country' and 'Moto Cross' motorcycles that was omitted from the later editions. It has also been expanded to include maintenance and repair data for both the leading link and telescopic fork variants of the 1971 to 1975 Sachs/DKW 'Enduro', 'Boondocker', 'Moto-Cross' and 'Hornet' motorcycles plus a 1972 illustrated 'Spare Parts List' for those models.
Obviously, this manual evolved in part due to the Sachs acquisition of both Hercules motorcycles in the late 1950's and DKW in 1966. However, it will also be of use to owners of any other motorcycles that utilized this series of 100cc and 125cc Sachs engines.
After the end of World War II, several motorcycle manufacturers were merged or absorbed under the Sachs banner and, in 1968 Sachs introduced their 100cc and 125cc 'Enduro', 'Cross Country' and 'Moto Cross' motorcycles for sale in the USA. The significance of the Sachs, Hercules and DKW mergers would soon become apparent as, while the Sachs motorcycles carried the 'Sachs' logo on the engine case, they featured a 'Hercules' identification plate on the steering head. In addition, Sachs ultimately decided to market their 'Enduros' and 'Scramblers' under the DKW badge and the original Sachs 'Enduro', 'Cross Country' and 'Moto Cross' models disappeared from the USA market in late 1971. However, they were replaced by 125cc DKW 'Enduro', 'Boondocker', 'Moto-Cross' and 'Hornet' models that were mechanically identical to the previous Sachs models, a true case of badge engineering.
In 1968 when Sachs introduced their 100cc and 125cc series of 2-stroke engines it was not long before the 'off road' and 'competition' world recognized their durability and performance. Consequently, within a short period of time Sachs engines were in use by a large number of other motorcycle manufacturers. Perhaps the most prominent USA manufacturer being Penton Motorcycles who produced their first competition Sachs powered models in 1968. Floyd Clymer quickly realized that there was a need for service and repair information for these engines and he set about preparation of an appropriate manual in early 1969.
