Motorcycles are measured using a Romer portable coordinate measuring machine - accurate to less than 0.05 mm - and PC-DMIS software.
The motorcycle is measured in a way that allows it's frame, swingarm, linkage and other components to be specified individually in MotoSPEC , "building" a virtual motorcycle.
Components can then be modified or swapped in and out of the "virtual" motorcycle, and the physical motorcycle does not have to be remeasured.
A MotoSPEC user can edit all chassis component dimensions and can even create a motorcycle from scratch.
The World Superbike series also relies on Romer and PC-DMIS to ensure that each motorcycle matches the manufacturer's homologated specifications.
