LMX 64: belt or chain transmission for my practice?

Posted By: Zoé Lieux On:

A technological breakthrough for the LMX 64

New since 2020

Today we are interested in the two types of transmission possible on the LMX 64: the chain drive and now the belt drive.

In fact, in recent months, we have made possible the optional mounting of a belt on our LMX 64s, replacing the standard chain mounting on these models.

We are proud to offer you this great technological advance, which, as you will see, has several advantages.

A choice that must be considered depending on the use

Now, who says choice also means thinking about what is the best solution for you. The transmission, whether chain or belt, should match your use and serve to optimize your LMX.

It is therefore important to understand what these two types of transmission are used for and for which uses they are best suited.


What type of chain ?

Originally, the LMX 64s have a light and versatile KMC chain.

A reinforced CZ go-kart chain is also available as an option, to maximize chain life and reduce wear on the sprockets. This chain is also available with a quick coupler unlike the original chain which must be riveted in place.

The advantages of the chain

Highly resistant on all terrains

The main advantage of chain drive is that it is very durable.

Thanks to the patented LMX double freewheel transmission which combines two independent chains, the breakage of the pedaling chain is also greatly reduced.

Less stress on the chain and therefore more freedom of movement!


The high resistance of the chain transmission therefore makes it durable over time. You can chain the kilometers (no pun intended) and thus enjoy all the power of your LMX.

In classic enduro use combined with good maintenance, you can consider doing 1500 to 3000 km off-road before changing your chain kit.

What use for the chain?

The chain drive is recommended for extreme off-road and trialising uses.

If you want to go through swampy or muddy paths, the chain will indeed have greater resistance than the belt.

Chain maintenance


Wash your chain after each use, this is essential to prevent rust, breakage and wear.


Chain lubrication always comes after a good wash. Regarding the type of fat to use, you should absolutely turn to specific greases for this use.

Indeed, using greases that are too thick and not dedicated can damage the equipment because residues will stick to the parts after lubrication.

Using a “dry” and non-sticky product is therefore the solution. Here are some examples of suitable products:

- WD40

- Muc-Off Dry Chain Lube (Motorcycle)

A first cleaning phase can be carried out using a penetrating product such as WD40.

Care should be taken not to put it on the discs as there is a risk of contamination of the pads. Once this is done, the chain should be wiped with a cloth.


The places to lubricate regularly on your vehicle are as follows:

- the chain tensioner

- the derailleur rollers

- the two chains

The frequency of lubrication therefore depends on the type of terrain on which you are riding and the conditions of use.

Chain noise

If you notice any unusual noise coming from the chain, check its tension and lubrication.

It should not be too loose so as not to derail or be too tight to keep all the swingarm travel and prevent breakage.

It is advisable to change the chain and the pinion every 1500 km or every 2 years when off-roading. Also check the proper functioning of the chain tensioner return spring.


What type of belt ?

The belt model we are currently using is the “Optibelt Omega HP”.

For the past few months, we have been testing a new model of belt, the “Poly Chain Carbon Volt”.

The first feedbacks are very positive, they are more resistant and durable over time.

These new belts are compatible with the kits delivered since December 2020 and will soon be available. For older kits an adapter roller is required and will also be available.

Technical improvements never stop at LMX!

The advantages of the belt

Silent transmission

The first and main advantage of the belt drive is that it is very quiet and makes the LMX 64 quieter than ever.

Since the engine is electric and already quiet, the sound of the chain is the most common element.

The strap is therefore THE perfect answer to make your outings even more enjoyable.

Easy to maintain

The belt drive also has the advantage of being very easy to maintain.

Unlike a chain, it does not need to be greased. No more oil stains on your clothes, the belt is the clean transmission par excellence!

Easy replacement

Another positive point to take into account is the ease of changing a belt compared to our original chain.

With the light weight and small footprint of a replacement belt, you can even have one attached to your bike ahead of time, so you can be prepared for any eventuality.

The optional belt kit on the LMX 64 makes it possible to switch from a chain to a belt without modifying the entire frame.

It is then up to you to choose which chain or belt is best for your use.

Light as a feather

The timing belt saves a few grams on the total weight of the bike because it is much lighter than a chain.

An advantage that weighs in the balance!

Less risk of derailment

Unlike a chain, derailing with a belt is complex. The only accident that can happen is breakage. One less worry is never too much!

What use for the belt ?

The belt drive is recommended for use on the road and on easy trails. It makes your trips even more discreet and your journeys even more pleasant.

We do not recommend it for extreme off-road use, however, as it is less resistant than a chain in this type of use.

Belt maintenance

As said before, a belt does not require a lot of maintenance.

It is important to clean your belt after each ride, to avoid friction with external parasitic elements and premature wear.

CAUTION : a belt does not be greased !

The belt only needs to be cleaned, not greased.


You are now an expert in transmission, well done !

The choice of chain or belt is up to you, and you have all the keys to decide which drivetrain is right for you.
