Question 1

What is the purpose of turn signal extensions?

Accepted Answer

Turn signal extensions are used when your motorcycle's turn signal stem is too short for your desired mounting position. They add length to the stem, allowing you to mount signals further out or at different angles on custom builds, cafe racers, or heavily modified frames.

Question 2

Will these extensions fit my turn signals?

Accepted Answer

These MCS extensions are compatible with most turn signals featuring M8 x 1.25 threading. Check your existing turn signal connector to verify the thread size before purchase. The 21mm thread length should work with standard assemblies, but measure your specific application if you have a non-standard setup.

Question 3

How do I install the wiring through the extension?

Accepted Answer

The body and nut are full-length slotted, which means they have grooves running their entire length. Simply feed your turn signal wiring through these slots during installation. The slotted design allows wiring to pass through without requiring disassembly of the extension.

Question 4

Is the black sleeve removable?

Accepted Answer

Yes, the black outer sleeve is completely removable. This design gives you flexibility for maintenance, repairs, or if you prefer a different aesthetic. You can remove it to access the inner body and nut, then reinstall it afterward.

Question 5

How much length do these extensions add?

Accepted Answer

These MCS turn signal extensions add exactly 27mm of length to your turn signal stem. This is often sufficient for custom mounting positions on cafe racers, bobbers, and heavily modified motorcycles where standard stems fall short.

Question 6

Are these extensions suitable for BMW Classic motorcycles?

Accepted Answer

Yes, these extensions work well on BMW Classic models like the K100 and other older BMWs, provided your turn signals use M8 x 1.25 threading. Many cafe racer builds based on classic BMWs benefit from extended turn signals to match custom frame geometry.

Question 7

What thread size do I need to check before buying?

Accepted Answer

These extensions use M8 x 1.25 threading. Before purchasing, verify that your existing turn signal assembly has an M8 threaded male connector. The thread diameter should be 8mm. If your signals use a different size (like M10), these extensions will not be compatible.

Question 8

Can I use these extensions with aftermarket turn signals?

Accepted Answer

Yes, as long as your aftermarket turn signals have M8 x 1.25 threaded stems. Many popular custom turn signal brands are compatible with M8 threading. Check the specifications of your aftermarket signals or contact the manufacturer to confirm thread size compatibility.
