Introduction
You are now the owner of a modern motorcycle which will give you and your children much pleasure with maximum safety, provided you look after and maintain the bike in good order. The manual supplied with your new motorcycle provides important information concerning the handling and maintenance of the bike. At the time of publishing, it included the latest technical details for this series. However, there may be minor differences due to constant developments in the construction of the motorcycles. The instructions for use are an important element of the motorcycle and, in the event of resale, should be handed over to the new owner. We would stress that all maintenance work to the chassis and engine should be carried out by specialised GAS GAS workshops. In the event that such maintenance is required while competing with the bike, the work should be carried out by a qualified mechanic. Please follow the recommended running-in times as well as the inspection and maintenance intervals given. Strict adherence to these time periods will have a direct affect on the working life of the motorcycle. In all cases maintenance services should be carried out by a specialised GAS GAS workshop to ensure the bike remains under guarantee. For your child's safety, only use GAS GAS approved spare parts and accessories. GAS GAS will not accept responsibility for any demage caused by the use of other parts. Please note that as parents you should be aware that the safety of your children depends upon you finding a safe location for the use of the motorcycle which should also be maintained in perfect technical order. Naturally, the motorcycle entails the possibility of risk, as with all vehicles, and therefore you should ensure that all basic precautionary measures are observed. To do so, follow the important instructions given to parents to ensure safe driving of the motorcycle. Riding your motorcycle off-road is a marvellous sport which we hope you and your children will enjoy to the full. Nevertheless, it can be a source of problems for the environment and of conflict with other people. Responsible behaviour when using your motorcycle helps to prevent these problems and conflicts. To guarantee the future of motorcycling, please ensure that you and your children use your motorcycle in accordance with the law, behave responsibly towards the environment and respect the rights of others. In conclusion we trust you and your children enjoy your motorcycle and always have a good journey. The right to modifications in the production and design is reserved - 4-
