The Isle of Man TT is such a unique race, people shouldnt judge this race as to wether they should buy or not buy motorcycles - the guys competing in it are highly skilled and even though it is a closed course on public roads, it still has all of the dangers present that you would find out daily driving that would not be on a traditional closed course racetrack. although... most guys dont go 150+ around curves on public roads with other traffic - if they do then they deserve the death thats coming for them.
