BMW has just patented two designs for carbon fiber motorcycle frames. One would fit supersport motorcycles, while the other could be used on a various range of body styles.
A report by Motorcycle News suggests that a performance-oriented beam-frame will be made of 'pultruded' carbon fiber, which involves making long tubes of the Carbon fiber strands that are "partially cured" for flexibility during assembly.
The report suggests that the "more adaptable" frame will be design made of small sections of hollow carbon fiber tubes, connected together to form a trellis.
It's not surprising that BMW is experimenting with carbon fiber on motorcycle frames. The company has already been successful at using carbon frames on the i3 and i8 electric cars.
