German Moped Days Tuning Guide
The parts shop MopedTeile is split by moped, then by Repair parts and Tuning. Public sources never print the horsepower or top speed the workbench preview is supposed to show.
I wanted a dyno chart. The CHALLS workbench screen says the preview will show horsepower and top speed, and then it does not leave a readable number in the upload. I wrote the shop categories and the one price sighting instead.
Repair versus tuning
The MBT tutorial says repair parts cover spark plugs, chains, brakes and tyres. Tuning covers cylinders, exhausts, carburettors and more power. Shop tabs seen on screen: Simson S51, Zündapp C 50 Sport, Puch Maxi S, Schwalbe /1, Schwalbe /2.
One frame priced a stock cylinder, piston and head at 41.47 €, an ignition assembly at 34.90 €, crank bearings and seals at 39.90 €, a crank seal at 8.90 €, a 3-speed gearbox service at 69.90 €, and a gasket set plus gear oil at 12.90 €. That is a single sighting.
From order to preview
Order the part, wait about a minute for the crate, then use the workbench (O in the CHALLS prompt) to fit it. Instant Deliveries, 199 Robux, skips that wait. Cheap Tuning, 199 Robux, is described by one wiki as 35% off parts. Neither effect has a second independent write-up.
Questions people ask
What is a full-tuned S51?
No public source lists the parts or the resulting speed. The S51 page keeps the prices and defects that were on screen.
