Original White Design Fuel Tap for Simson KR51 Schwalbe S50/51 SR50/80 and more models with M16x1 Tank Connection

A disrupted fuel supply is one of the most common causes of engine misfiring, poor throttle response or starting issues in classic Simson motorcycles. This fuel tap in original design configuration is specifically engineered for Simson tanks with M16x1 thread and ensures a controlled, clean and consistent fuel flow. Equipped with an integrated brass filter screen and a white sediment bowl (water trap), it supports reliable carburetor performance even in older fuel tanks.

Compatible Simson Models (All Production Years)

This fuel cock is suitable for all production years of the following Simson models:

Model	Year of Manufacture	Manufacturer

KR52	All years	Simson
S50	All years	Simson
S51	All years	Simson
S53	All years	Simson
S70	All years	Simson

Technical Construction and Functional Design

M16x1 Precision Thread for Direct Tank Fitment

The fuel tap features an M16x1 tank thread, matching the original Simson specification. This ensures precise alignment with factory fuel tanks and secure mechanical sealing between tank and valve body. Correct thread compatibility is essential to prevent fuel leakage and inconsistent fuel supply.

Integrated Brass Filter Screen and Black Sediment Bowl

Contaminated fuel is a frequent issue in vintage two-stroke motorcycles, particularly when tanks show internal corrosion or sediment buildup. This fuel tap addresses that issue through a two-stage filtration system:

Brass mesh screen positioned inside the tank to block coarse debris
Black sediment bowl for collecting water and fine particles
Removable lower section for inspection and cleaning
Improved protection of carburetor jets and float valve

If your Simson engine hesitates at higher RPM, stalls under load or suffers from clogged carburetor jets, the cause is often insufficient fuel filtration. The integrated filter design helps reduce these issues by stabilizing fuel purity before it reaches the carburetor.

ON / OFF / RES Fuel Flow Control

The fuel valve includes three defined operating positions:

ON – Standard fuel supply
RES – Access to reserve fuel level
OFF – Complete fuel shutoff

The reserve function is particularly relevant for classic Simson motorcycles without fuel gauges. When the engine begins to lose power in the ON position, switching to RES allows continued riding using the remaining fuel volume in the tank.

Application Range and Vehicle Types

This fuel tap is suitable for multiple Simson vehicle categories, including:

Light motorcycles
Mopeds
Mokicks
Small displacement two-stroke bikes
Restoration and tuning projects

Manufactured as a high-quality replica by wilmat, this component is designed for restoration in original appearance as well as for technically optimized setups.

Technical Solution for Common Simson Fuel Supply Issues

If your Simson motorcycle experiences irregular fuel flow, carburetor contamination or sudden engine cut-outs, replacing a worn or clogged fuel tap is often necessary. This original-style M16x1 fuel tap restores defined fuel regulation and improves operational stability by combining mechanical shutoff, reserve function and sediment filtration in one compact assembly.

For restoration projects, daily riders or tuned two-stroke setups, this fuel tap provides a technically appropriate solution aligned with original Simson tank specifications. Its functional design supports consistent carburetor operation and helps maintain predictable engine performance across all compatible Simson models.
