This is a recent weekend trip myself (on my TTR) and some mates (on other bikes Yamaha DT 200, Honda, BMW) made recently.
2 warnings, one for language and the other for boredom as although it was fun for us I appreciate it may just be boring for others (although broken up into 4 parts the footage is an hour long) so if you have a spare hour and feel like a laugh at my expense (two spills) grab a cold beverage and have a look.
