Strong brands have deep roots

It was as long ago as 1917 that the pioneer Arnold Bucher began manufacturing the leather and floor cleaning agent REX in Bützberg near Langenthal. With the increasing development of motor vehicles there was a shift in business operations and in 1947, REX became MOTOREX.

The MOTOREX-BUCHER GROUP AG continues to operate as an independent family business – something in which we take great pride. Our employees feel respected and appreciated and this is an attitude they themselves embrace in practice.

The group of companies consists of the following:

  • MOTOREX-BUCHER GROUP AG as holding company in Langenthal, Switzerland.
  • MOTOREX AG, as the parent company of the Group
  • MOTOREX-TOPTECH AG, for the sale and installation of workshop equipment.
  • MOTOREX (D) GmbH in Schriesheim near Heidelberg, Germany
  • MOTOREX (A) GmbH in Hallein near Salzburg, Austria
  • MOTOREX (USA) Inc. in Brookfield CT
  • MOTOREX NORDIC AB in Gothenburg (S)
  • YORK SAS in Toulon (F)
  • MOTOREX Poland Sp. z o.o. in Ostrowiec Świętokrzyski

MOTOREX is growing both in Switzerland and internationally: today, more than half of its lubricant output are sold outside Switzerland. This is possible due to our 190 sales partners, who contribute their product and industry expertise in 94 countries, as well as our own sales organisations in Switzerland, France, Germany, Austria and Sweden.


For many years, MOTOREX has collaborated closely with manufacturers and racing teams in order to provide professional and amateur athletes in cycling and motorcycling with the best products and up-to-date expertise.
