Superbikes on the test bench

Article in MOTORRAD 08/2021 on the BMW M 1000 RR and the high (test) requirements for superbikes

‘Superbikes’ are near-production, fully enclosed high-performance racing machines with a maximum displacement of 1,000 cm³ that are based on freely available road bikes of the same model. Among others, they are used in the World Superbike Championship. To ensure that the superbikes remain close to series production, the technical freedoms are limited by the regulations. While entire subassemblies of chassis parts, brakes, tanks, and wheels can be replaced by racing parts, the degree of freedom for engines is strictly regulated. In the World Superbike Championship, for example, only camshafts, cylinder head ducts, and gear ratios may be changed. Everything else remains the same as for the production counterpart.

Due to the intensive forces acting on them, high-performance engines for racing have to meet much higher requirements than conventional machines. Higher speed mean more power and thus higher demands on load-bearing capacity. Friction losses and tolerances must be minimized. The challenge here is to build base engines that are as equivalent as possible to reduce series dispersion. As written in the article ‘Auf Hochtouren’ in MOTORRAD, issue 8/2021 (only available in German), around 100 racing engines are produced annually at the BMW plant in Berlin, which are then used by Superbike and Endurance factory teams. The production time and thus the testing of the high-performance engines are far more elaborate than for conventional motorcycles.

Testing is a linchpin in the design of racing machines

Accordingly, completely different requirements are placed on the testing and inspection of the components. Endurance runs, performance tests, meticulous analysis and evaluation of test data are a linchpin in the design of racing machines, and not just because of the strict regulations. This article provides a practical insight into the challenges involved in developing superbikes (link to PDF). To test the superbike engines, BMW uses, among other things, a PAtools TX controlled engine test bench that automatically runs through and evaluates the various test cycles. PAtools TX from KRATZER AUTOMATION is a state-of-the-art, scalable user interface that offers maximum user-friendliness and adaptability.
