I've not even been riding for 2 years yet and only started watching motorcycle racing this season.

Well you have to start some time, welcome to the fan club, motorycycle racing is adictive, but can be complicated at first.
Several different types of racing, different classes, ect. It took me a season or two to get my head around all the different racing. At first I only watched or attended AMA racing here in the US, but then discovered WSB and GP racing.
I'm sad now, because the racing season is over.
