![]() ![]() BMW has the opportunity to do more than just increase the durability and performance of the bike - they can create a whole new design with the texture and color of carbon fiber. ![]() Given that BMW currently has facilities devoted to mass manufacture of carbon parts, mass manufacture of bolt-on frame stiffeners would be a simple and low-cost way to incorporate the benefits of carbon into a motorbike chassis.īy mass-producing the carbon fiber motorcycle frame, BMW has once again shown the world that it has what it takes to be one of the world's top brands. However, the concept has not yet made it to production motorcycles, until now, and BMW's patent adds a new twist to the concept by making the carbon pieces detachable and changeable. The first feature that differentiates rigid frame motorcycle choppers is the fact that they lack a rear suspension. Today's MotoGP motorcycles often incorporate carbon reinforcing plates carefully positioned on their aluminum frames, delivering extra stiffness in torsion or flex precisely where it's needed. You are correct in thinking that this concept is not entirely new. As an added plus, the design removes the need to weld aluminum stiffeners into the chassis, which adds heat that may disrupt or affect the alloy's qualities. Another carbon brace will be connected to the frame's opposite side. It mounts to the case through five threaded holes, four of which are already present on the existing S 1000 RR chassis. The carbon component is depicted in the patent near the frame's corner, above the swingarm pivot, where the subframe attaches to the main chassis. The BMW design also streamlines assembly on a manufacturing line, with more subtle benefits seen in the frame structure itself. Simply altering the direction of the carbon fiber weave changes the stiffness properties of the material. As riders learned how much the frame contributed to the ride, handling, and performance of a motorbike, frame technology evolved right alongside other motorcycle components. One advantage is that the panels are not permanently bonded, so the carbon components can simply be replaced with a new design, maybe to meet the stiffness requirements of a specific circuit or a rider's preferences. Early motorcycle frames served chiefly as a mounting point for all the things that make a stack of tubing different from a motorcycle. The motorcycle frame allows the manufacturer to create a new plating on top of the original bike frame. ![]()
