# Cybex 750T 770T 751T 625T 650T Treadmill AC Drive Motor MR-22239 KSP128 (MP17)

\## Cybex Treadmill AC Drive Motor MP17

The Cybex MP17 Treadmill AC Drive Motor is a replacement drive motor for select Cybex commercial treadmills. It helps power the treadmill’s belt drive system and is intended for machines that use the MR-22239 or KSP128 motor reference. This motor may suit a repair or refurbishment project when the original treadmill drive motor has failed, worn out, or requires replacement.

Each motor has been inspected by skilled technicians before sale. The inspection helps confirm the part’s condition and supports safe, reliable use in the intended treadmill application. This is a used fitness equipment part, so it provides a practical option for extending the service life of an existing Cybex treadmill instead of replacing the complete machine.

## Product Details and Benefits

This product is a treadmill AC drive motor sold under the following identifiers:

\- \*\*Brand:\*\* Cybex  
\- \*\*Product type:\*\* Treadmill drive motor  
\- \*\*Motor type:\*\* AC drive motor  
\- \*\*Product name:\*\* Cybex MP17 Treadmill AC Drive Motor

The motor forms part of the treadmill drive system. When correctly matched and installed, it can help restore the drive function of a compatible treadmill. Replacing the motor rather than the entire machine can help reduce repair costs and keep otherwise serviceable fitness equipment in operation.

Because this is a used replacement component, the appearance may vary from one unit to another. The seller carries multiple units, and photographs may show a representative part rather than the exact motor shipped. The part supplied will match the listed model and component type.

## Compatibility and Applications

The Cybex MP17 AC drive motor is listed for use with these Cybex treadmill models:

\- Cybex 750T  
\- Cybex 770T  
\- Cybex 751T  
\- Cybex 625T  
\- Cybex 650T

It is also associated with Cybex treadmill drive motor part numbers \*\*MR-22239\*\* and \*\*KSP128\*\*. This replacement motor is intended for treadmill repair, maintenance, and equipment refurbishment. It may be suitable for fitness centers, gyms, service technicians, and treadmill owners maintaining compatible Cybex equipment.

Compatibility depends on the exact treadmill configuration and the motor installed in the machine. Model names alone may not confirm a direct match, so compare the part number, motor identification, connectors, mounting arrangement, and other relevant details with the existing component before ordering. The product page does not provide dimensions, electrical ratings, mounting specifications, or installation instructions, so those details should be confirmed separately when required.

\## Why Choose This Replacement Motor?

The MP17 gives buyers a way to replace a Cybex treadmill AC drive motor without sourcing an entire treadmill. Its inspected used condition can make it a suitable choice for repair work, equipment restoration, or keeping an older commercial treadmill in service. Reusing a fitness equipment part also helps extend the working life of existing equipment and reduces unnecessary waste.

## Before You Buy

Confirm that your treadmill is a \*\*Cybex 750T, 770T, 751T, 625T, or 650T\*\* and check whether the existing motor carries reference \*\*MR-22239\*\* or \*\*KSP128\*\*. Verify all available identification details before purchase. For installation, use a qualified treadmill repair technician if you are unfamiliar with AC drive motor replacement or commercial fitness equipment servicing.
