Every innovation starts with a simple question.
Why is this still so difficult?
For Pure-Moto, that question was asked in a small workshop after another long day at the motocross track.
Bonne spent countless weekends supporting his two sons as they pursued their passion for motocross. Like every racing family, the day didn't end when the final chequered flag dropped. The bikes still needed to be cleaned, maintained and prepared for the next race.
One job always stood out.
Adjusting the chain.
What should have been a quick maintenance task was surprisingly time-consuming. Measuring both sides of the swingarm. Counting adjustment marks. Looking down the chain. Measuring again. Tightening the axle. Checking if the wheel was still perfectly aligned. Loosening everything and starting over because one side had moved ever so slightly.
There had to be a better way.
Bonne shared his frustration with his brother Harmen. Both believed that something as fundamental as chain adjustment shouldn't rely on guesswork. Together they began developing an entirely new system—one that would make chain adjustment faster, more accurate and completely repeatable.
The goal wasn't to improve the existing chain adjuster.
It was to reinvent it.
As the first working prototypes proved themselves, another important chapter began.
Bonne's longtime friend Mathieu, a former Grand Prix motocross mechanic with decades of experience at the highest level of the sport, immediately recognised the potential of the concept.
Having worked alongside world-class riders and factory teams, Mathieu understood that any new product must first earn its place in the paddock.
Through the professional race team he was working with, the first Pure-Moto prototypes were tested under genuine race conditions. Feedback from professional mechanics and riders led to continuous improvements, ensuring every detail met the standards demanded by elite competition.
Mathieu's extensive network throughout the European and international motocross industry also opened doors to respected riders, mechanics, distributors and technical specialists. Their experience and feedback became an essential part of refining the Pure-Moto system into the product it is today.
The result is a completely different approach to chain adjustment.
Instead of relying on visual markings, rulers or estimation, the Pure-Moto Chain Tensioner uses an engineered precision click mechanism. Every click moves the rear axle exactly the same distance on both sides, ensuring perfect wheel alignment every single time.
No guessing.
No uneven axle alignment.
No loose chain blocks falling from the swingarm during wheel changes.
Just fast, repeatable precision.
Manufactured from aerospace-grade 7075 aluminium and combined with premium titanium components, every Pure-Moto Chain Tensioner is built to withstand the demands of professional motocross, enduro and off-road racing.
Its lightweight construction, premium anodised finish and titanium nitride coating reflect the same philosophy that guided the project from day one:
Engineering should solve problems—not create them.
Pure-Moto has never been about creating another aftermarket accessory.
It is about making every ride easier.
Every wheel change faster.
Every chain adjustment more accurate.
Every mechanic—whether it's a factory technician, a weekend racer or a parent working in the paddock—more confident that the job has been done perfectly.
Because the best ideas don't come from boardrooms.
They come from muddy boots, late nights in the workshop and hundreds of hours spent at the racetrack.
That is where Pure-Moto was born.
And that is where every new product will continue to be developed.
