There are many brands and models here on display and all of have them have a story. At first glance it can seem a little overwhelming but if you dive in and learn the story behind the ones you find interesting it will be a most enjoyable visit. I reccomend multiple visits. I find something new and interesting every time I'm there. The staff here is top notch.
There are quite a few,covering many years and many type's. Mx ,hill climb speed, off road ,road and a couple that are one of a kind.
That's a very big question, Are you asking motorcycles worldwide that are in production to day, Are you asking how many motorcycle companies has there been worldwide to include the ones that have failed in the past And are no longer in production, Or are you asking how many different types of categories of motorcycles are there And have been.
Look at google
Lots and lots from street bikes to dirt bikes and mini bikes.
