To ensure that the reduction of the primary wheelbase did not create additional problems, the engineers also worked on the dimensions of the cooling circuit and, more specifically, on the section where the fluid goes through once it enters the engine, located between the crankcase and the transmission assembly. Here, the shape of the conduit near the fluid input and output point has been revised to compensate for the narrowing that has been created, where the walls of the gearbox and those of the crank chamber almost touch each other. The fluid, as it flows through this gap, must attempt to transmit as little heat as possible, otherwise there is the risk that the mixture will heat up too much before entering the combustion chamber. For the same reason, the lower part of this amount, at the entry point of the fluid, is now exposed more to the airflow, as this is seen by opening the crankcase.
