BMW's new M Motorsport frame for M 1000 RR saves about 1.3 kg and arrives for 2027

BMW Motorrad is introducing the third generation of the M Motorsport frame in the BMW M 1000 RR. It combines insights from racing with digital development methods and highly specialised manufacturing processes. The aluminium frame is lighter and offers a precisely tuned balance of stiffness and flexibility, which BMW says enables more precise handling, clearer feedback and more consistent tyre contact, particularly during sporty riding and on the racetrack. From model year 2027, the new M Motorsport frame will be fitted as standard in the BMW M 1000 RR.

Compared with the previous version, the third-generation frame is around 1.3 kg lighter, which BMW says enhances agility and facilitates rapid changes of direction. Wall thicknesses reduced by up to 30 per cent allow targeted tuning of stiffness and flex characteristics. At lean, the frame can flex laterally to a defined degree, supplementing the suspension in absorbing inputs from the road surface, so riders get more consistent tyre contact, improved feedback and more even wear characteristics. Longitudinally, the chassis retains high stiffness to transmit braking and drive forces precisely and keep response predictable under high loads.

BMW Group Plant Landshut uses low-pressure casting to feed molten aluminium into the mould in a controlled manner, reducing turbulence and air inclusions. Temporary quartz sand cores create the cavities specified by the design, and a core-shooting simulation maps flow behaviour, packing density and curing before tooling is manufactured. In the cold-box process, the sand cores are produced, cured and positioned precisely in the casting mould; after casting, the cores are removed, followed by machining and comprehensive quality inspection. X-ray inspection, wall-thickness measurements and coordinate measurements check internal quality and dimensional accuracy before the components go to Berlin.
