At the BUB there are two sidecar classes.....one for "normal" sit-on sidecars.....and one for sidecar streamliners........Any and all type of fairings are allowed on the "normal" sidecars, as long as the driver and passenger are able to exit the outfit without restrictions. Both classes (normal and streamliners)
pay price money for the fastest.........Not a record, just the fastest one way run for the event.........
You have the option of using a passenger in the sidecar..... or no passenger but 60kg weight is required.
There are various displacement classes......350c.c....500c.c.....650c.c......750c.c.....and so on.
And like Willie noted NO naked riders......naked sidecars are OK.....................
