Lightweight Design for Winners - Rear Frame of Motorcycle

Structural components are exposed to severe conditions in motocross sport and, as a result, are often made of die-cast metals. Despite this, intelligent lightweight design solutions can also be achieved for these applications us-ing high-quality performance polyamides. This is illustrated by the exa

Motocross machines need to be extremely tough and resilient. Long jumps, rough ground and riding close to the limits really takes it out of the bikes so that structural parts often need to be made of aluminium or steel. The weight, however, has a direct influence on the handling and vehicle dynamics and as usual, lighter is better. This makes the trend towards lightweight design a current topic for motorbikes as well.


Weight in focus

The Swedish manufacturer Husqvarna Motorcycles is always looking to further develop its models and this is the reason why the rear frame of the FC 250 and FC/FS 450 models was to be made of polymer materials instead of the previously used traditional aluminium. An ambitious project as the application puts extremely high demands on the material used. Along with high torsion and flexural stiffness, extremely high impact strength is required. The material must also have good surface quality and be UV resistant, but the most important factor is the maximum possible reduction in weight in order to further improve handling of the bike. Converting the component to a polymer material needed to take all these points of view…
