The time taken to do the stunt, be it ten minutes or ten years, makes it no less of a stunt. When the R1 is modified to make it more suitable for the adverse conditions for RTW, (ie. bars, tires ect..) it takes the narrow focus of the R1 away so that it is no longer an R1! Personally, I love seeing people use a motorcycle that was not designed for the purpose of RTW, use it for such. Riding a Harley to the Artic circle is not the same thing as riding the Dempster on a R1.
My hat is off to Mr. Sjaak and I will now read more about his exploits.
