German Moped Days Tuning & Builds is easiest to manage when you choose the driving result first: a faster S51, an MTX engine build, or a controllable Wheelie build. Repair the moped, confirm that it starts, and then buy a compatible group of Cylinder, Piston, Exhaust, Air Filter, and Gearbox parts. The available evidence does not establish a complete official price, compatibility, or performance table, so use the in-game Tuning prompts and your own repeatable road test as the final check.
Pick a build goal before buying
Do not treat every named build as a fixed kit. MTX 110, MTX 130, MTX530, Full tuned S51, and Wheelie build are target configurations or player descriptions. They can require different parts and controls.
| Build goal | Prioritize | Use it when |
|---|---|---|
| S51 speed build | Cylinder, Piston, Exhaust, Air Filter, and compatible Gearbox | You want to compare acceleration, gears, and top-speed tests |
| MTX 130 build | Cylinder Head, Piston Kit, MTX parts, and a matching Exhaust | You are following an MTX-focused engine assembly route |
| MTX530 build | MTX cylinder, 5-speed Gearbox, sports filter, Exhaust, and compatible clutch | You want a high-power S51 configuration and can verify each fit in-game |
| Wheelie build | Power parts plus Clutch, throttle, gear, and a suitable test road | You want front-wheel lift and can practice control rather than only chase speed |
| Full-tuned S51 | A complete cost calculation before ordering every upgrade | You are tuning a vehicle for use or resale and accept the financial risk |
The reported MTX530 discussion gives approximately 34.5 PS and 147 km/h, but those are video-reported figures, not stable official specifications. Treat them as a test target, not a guarantee. The same caution applies to any exact speed claimed for a full-tuned S51.
Repair before installing tuning
Performance parts cannot compensate for a vehicle that is missing fuel, has a dirty air filter, has a stuck or damaged piston, or has brakes that have not been released. Use this order:
- Inspect the vehicle. Check the engine, fuel, drivetrain, brakes, and visible parts in the
WorkshoporGarage. - Repair the base vehicle. Order missing parts from the
Parts Shop, wait for delivery, and install or repair them at theWorkshop. - Start and baseline-test it. Confirm fuel, ignition, starting, throttle, braking, steering, and gear changes before changing performance parts.
- Set aside tuning money. Include the vehicle cost, repair parts, fuel, and expected resale value; do not assume tuning pays for itself.
This separation prevents a basic repair problem from looking like a failed upgrade. If the engine will not run after an installation, check the piston, cylinder, fuel, air filter, and ignition before buying another performance part.
Match the parts as a system
The useful relationship is compatibility, not an isolated “best part.” The supplied tuning records name the following roles:
| Part | Role in a build | Check before installation |
|---|---|---|
| Cylinder | Core engine power and speed component | Vehicle fit and matching piston, head, filter, and exhaust |
| Piston / Piston Kit | Completes the engine assembly with the cylinder | Correct kit for the target cylinder; a damaged piston can stop normal operation |
| Cylinder Head | Early component in the MTX 130 assembly route | Matching MTX configuration and installation prompt |
| Exhaust | Supports engine output and high-speed testing | Compatibility with the cylinder and air intake |
| Air Filter / Sports Filter | Affects engine operation and some tuning combinations | Clean condition and the filter type requested by the build |
| Gearbox | Changes available gears and speed control | Whether the engine and vehicle accept the selected gearbox |
| Clutch | Affects starts, shifts, and wheelie control | Vehicle and drivetrain fit; do not assume 6V clutch works everywhere |
The MTX530 route is commonly discussed with a 5-speed Gearbox, sports filter, suitable exhaust, clutch, and MTX parts. That combination is a reported configuration, not a universal requirement for every moped. If the game rejects a part or shows an installation warning, follow that in-game result rather than forcing the planned build.
Review the MTX530 tuning parts
This moment supports the MTX530 parts route by covering the high-power cylinder, 5-speed gearbox, sports filter, exhaust, clutch, and related MTX components described here.
Test a build without losing the comparison
Use a controlled loop after each meaningful group of changes:
- Record the baseline: starting behavior, acceleration, usable gears, braking, and a speed reading on the same road.
- Install one related group, such as the engine parts first or the intake and exhaust pair. Do not replace everything before the first test.
- Check fuel, ignition, air-filter condition, brakes, and vehicle damage again.
- Repeat the same route in the same direction and compare starting, gear changes, speed, and control.
- Keep the configuration only if it serves the selected goal. Remove or replace a part through the
Tuningmenu when the result is worse or the fit is wrong.
Road surface, fuel, vehicle state, and player control can change the result. A single high-speed run does not prove a permanent maximum, and high power does not automatically make a vehicle easier to wheelie.
Build for wheelies with control
A wheelie setup is a separate handling goal. The recorded examples connect a large MTX cylinder and better exhaust with lifting the front wheel in first gear, but the maneuver still depends on Clutch, throttle, gear selection, road, and timing. Start in an open area, use a low gear, and practice smooth throttle and clutch input. If the front wheel will not lift, check that the engine is actually producing power before buying more parts; if it lifts too aggressively, reduce the input or change the configuration rather than treating maximum power as the only answer.
Practice the MTX wheelie setup
This moment supports the wheelie setup by linking a large MTX cylinder and better exhaust with lifting the front wheel in first gear.
Calculate the resale risk
Before a full tune, write down the expected total:
vehicle price + repair parts + tuning parts + fuel = total investment
Compare that total with the sale amount you can realistically expect. A recorded S51 example used roughly 4,000 total and sold for roughly 7,500, but it is one player case and does not establish a fixed profit or a universal value for a full-tuned S51. High-cost tuning may improve the driving experience while reducing the margin on a resale vehicle. Test the vehicle first and keep the configuration that matches your purpose.
FAQ
Is MTX530 the best build?
It is described in player material as a high-power configuration, but “best” depends on whether you need speed, wheelie control, reliability, or resale margin. Its reported 34.5 PS and 147 km/h should not be treated as guaranteed game values.
Does a 5-speed gearbox work with every moped?
The supplied evidence does not document universal gearbox compatibility. The 5-speed gearbox is associated with the MTX530 discussion; check the vehicle's current Tuning prompt before buying it.
Why did tuning not make my moped faster?
Check fuel, ignition, brakes, damage, piston, cylinder, and air filter first. Then confirm that the exhaust, gearbox, and other parts match the engine. Test on the same road rather than comparing unrelated runs.
Are complete tuning prices documented?
No. The available evidence names parts and build goals but does not provide a complete, stable official price list, gear-ratio table, maximum-speed table, or compatibility matrix. Use the current in-game shop and installation prompts.

The named parts, MTX configurations, repair-first route, and testing cautions are based on the supplied community wiki snapshots and recorded player videos. The MTX530 performance figures, wheelie behavior, and resale example are reported observations rather than independently confirmed game-wide values. The supplied evidence does not establish complete prices, universal compatibility, fixed gear ratios, or stable maximum speeds; the current in-game Tuning and installation results are decisive.
