GAS GAS thanks you for your confidence

By choosing the new GAS GAS Pro 2004 you have just entered the great GAS GAS family and, as a user of the number one off-road motorbike manufacturer, you deserve the distinguished treatment that we wish to offer to you both in our after-sale relationship and in the explanations that we provide in this manual.

Our Pro 2004 is a bike conceived for the practice of high-competition trial. It is actually the fruit of many years of competition and experimentation in this demanding discipline, as well as the many great successes achieved thanks to great trial riders who have contributed with their expertise to the basic data that have allowed us to create a high-level motorbike, a GAS GAS which counts on its low weight as a significant key factor.

Congratulations for making the right choice. With your skills at the commands of this motorbike, an adequate preparation and the indispensable servicing for this GAS GAS to be highly reliable, you will be able to enjoy the most comfortable and rewarding trial practice.

Thanks for your confidence and welcome to GAS GAS Motos.
