Mitoos MXL z65 timing belt

The Mitoos MXL z65 timing belt (CXM465): transmission precision for the most demanding Slot Raid

When the transmission is the heart of your Slot 4x4, every component matters. The CXM465 belt from Mitoos is specifically designed to meet the requirements of Raid and Rally models where traction continuity, especially on uneven surfaces and technical sections, makes the difference between scoring points or being out of the race.

Features and function

• Teeth: 65 (z65).
• Width: 2 mm.
• Pitch: Standard MXL.
• Application: Synchronous transmission in 1/32 scale Slot Raid and Rally-Slot cars.

The MXL profile is one of the most widely used standards in small format synchronous transmissions, ensuring precise tooth geometry and a snug fit on approved pulleys. With 65 teeth, this belt allows for detailed adjustment of the wheelbase and the gear ratio of the 4x4 system, which is particularly relevant in competition-oriented setups.

Compatibility

The CXM465 belt has been designed to work in combination with the Mitoos toothed pulleys: both the plastic versions (references M136 to M140) and the competition aluminium ones (references M143 to M149). The 2 mm width ensures correct fitting across this family of pulleys, without the need for additional modifications.

Installation and preparation

When installing the belt, it is advisable to check the appropriate tension before permanently fixing the position of the motor or pulleys. Insufficient tension can cause tooth skipping during sudden accelerations; excessive tension generates friction and may reduce the lifespan of the belt. The number of teeth (z65) makes it easier to find the ideal mounting position for various common wheelbase configurations in available Raid chassis.

Common errors

The most common mistake when working with small format toothed belts is mixing MXL pitch belts with pulleys of a different pitch (e.g. GT2). Although they may look similar visually, the tooth profile is not interchangeable, resulting in a poor fit that causes vibrations and loss of traction. Always ensure that both the belt and the pulleys share the same standard pitch.

Frequently asked questions

How many teeth does this belt have and why does that number matter?

It has 65 teeth (z65). The number of teeth determines the total length of the belt and, therefore, the wheelbase that you can cover with it. Choosing the belt with the correct number of teeth is key to properly adjusting the transmission of your Slot 4x4.

What does MXL pitch mean?

MXL is a standardised pitch for small pitch synchronous belts (0.080 inches between teeth). It is one of the most used in precision transmissions in miniatures and small format mechanisms, making it easier to find compatible pulleys within the Mitoos range and, in general, in the Slot spare parts market.

Is it compatible with pulleys from other brands?

As long as the pulley has MXL pitch and a width equal to or greater than 2 mm, the technical fit is possible. However, to ensure optimal performance and avoid alignment issues or premature wear, we recommend combining it with the toothed pulleys from the Mitoos range for which it has been designed.

What Slot disciplines is it intended for?

Mainly for Slot Raid and Rally-Slot in 1/32 scale, where cars use 4x4 traction with toothed belt systems. It is a frequently used spare part in club competition setups and in custom long-distance chassis builds.

When should I replace the belt?

When visible signs of wear appear on the teeth, when you notice loss of traction without apparent cause in the motor or wheels, or when the belt has lost tension and cannot be recovered by adjusting the position of the components. In competition, many preparers check it preventively in each maintenance session.
