Eh, no, the guinnes world record was about "The longest continuous journey by motorcycle within a single country is 16,240 km (10,091.05 miles) by Ryan and Colin Pyle (both Canada), who toured China between 16 August and 17 October 2010."

Before that there was a similar world record too, the lenght of the trip inside the country was just shorter.


Edit: Or who knows if there was such Guinness world record. Maybe the trip was first to be acknowledged. However there has been similar things done whether they has been taken as world record or not.
