There are significant overlapping between subclasses B62M and B62K, the latter dealing more with the cycles frame aspects. In practical most of the documents classified for example in B62M 25/00 (actuators for gear shifting) are also classified in B62K 23/00 (Rider operated controls specially adapted for cycles). Similarly motorcycles in main group B62M 7/00 characterised by position of motor or engine have a strong relationship with main group B62K 11/00 dealing with frames for motorcycles, engine assisted cycles or motor scooters.
