Hercules! A byword for quality from Bavaria. Founded by Carl Marschütz in 1886, the company exclusively produced bicycles until 1928. The production of light motorbikes up to 200 ccm³ became profitable again due to the abolition of the driving licence and tax obligation. Due to the close co-operation with Fichtel & Sachs in the bicycle segment, F&S engines were used for the mopeds, mokicks and mopeds.
Here you will find a 70 cc tuning cylinder kit with a bore of 41 mm and a 12 mm piston pin. The cylinder is the running and limiting surface for the piston. The entire combustion process takes place in the cylinder. This makes it one of the most important components on your Hercules with the fan-cooled Sachs 50/3 and 50/4 engines. In addition to the cylinder, the set also includes a piston set.
Attention! Tuning part! Not permitted in the STVZO area!

Broken upon arrival
i have gotten a sylider that i ordered from this website. when it arrived i tryed to put the sylider on. then i notced that the piston didnt want to fit on the sylider with the compression rings. then i found out the there was a big crack in the sylider wall. so the sylider is broken and the piston wont fit beacuse the rings get stuck on the big crack.
We regret that the cylinder arrived defective. Please contact our customer service so that we can process your complaint.
