The years pass, the successes are linked, the encouragement are confirmed and motivate...

The story begins in 1961, when Chris falls in love at first sight at the age of 15.
A student in Paris at the time, Chris stumbles across a battered 125cc Motobécane for sale “as is”.

After buying this wonder, he spends a year carefully and painstakingly working on the battered wreck with his friends, completely renovating and transforming it into a 200cc racing machine for the French Trials competition.

The course of Chris Rayer in a few lines…


With this machine, he wins his first victory in the French national Trials championship. He finishes the season in the national top 5 and so classifies for the following season’s “inter” category.


Chris scrimps and saves to buy, from England, the first “real” Greeves competition motorcycle so that he can compete with the top international riders of the time on equal terms.
The results speak for themselves: in the first season è Chris Rayer becomes the French “inter” vice champion.

From 1965 to 1968.

Now French “inter” champion, he regularly finishes European championship races in the first three positions. Montesa’s doors are opened wide to him. The company chooses him as its top rider to help it to develop a new machine that will represent the Montesa name in French races and abroad.

1968. The result ? The Montesa Cota 247 — the first production model in a long lineage of competition machines that still exists to this day.


Chris also joins Honda France.
Drawing on his skills as a technician and developer, he sets up, in Paris and elsewhere, a technical school providing training on the manufacturer’s models for its dealerships.
Honda is already famous for its high performance four-stroke engines and this training is very successful, lasting several years.


Chris opens the first shop specialising in trail bikes in Paris, with the name “Moto 92”, in Chaville.


1970. A new adventure begins. Chris leaves Montesa to join Yamaha, which asks him to create, with the backing of the Hamatsu Japan plant, the company’s first 250cc Trials bike prototype.


1973 sees the production launch of the Yamaha TY motorcycle, the first ever Japanese trials bike. Thus begins an enormous technical and commercial success story worldwide.


The first Engine Kit is created : TY 350 CC.


To meet growing demand from customers wanting similar engine performance and benefit from Chris’s experience gained during his top-level racing years, Moto 92 creates an Engine Kit department.


In response to the craze for trail bikes, Moto 92 opens the first school for trail bike riders, “Trial Moto-Verte-Yamaha”, in Paris. For some years, this school helps to train and encourage hundreds of trail bike riders.

From 1977 to 1980.

Makes one of the first French ULMs. Designs and creates a 200cc two-cylinder engine (2x100cc independent linked cylinders) for a “Quick-Silver-USA” ULM è Altitude reached: 1,500 m at 60 kph.

By working only with the best, each of which is an expert in its own field, Chris Rayer creates engine parts that combine quality and performance with easy fitting on the main Yamaha engines.

An example : the 600cc Kit, which was created for the famous 500 XT, has also been an enormous success.

Customers write to tell us that they are still using 600cc engines with 150,000 km already on the clock. This information is for the attention of competitors that, for several years, have attempted to emulate us and like to spread rumours about the quality of certain products, thinking, of course, that they alone have the appropriate expertise. We will not quote names, as they can be found very easily on the Internet.

Thousands of the highly-successful kits have been sold, some of which are still in use on motorcycles that are running even today, many years later.
