mainly one reason at the time ...............money , thought this would be the cheapest option . probably spent more over the development than I would have a 4rt to be honest, but like most having the money all in one go just doesn't seem to happen. always love a challenge and fabrication too . I ride it every weekend and its a blast , not found one hill yet that it wont fly up . but one major drawback athough it has twice the power in bhp of most trials bikes it stalls, unless your quick on the clutch after and obstacle either a rock or a log.
said and done I love it , more than any other bike I have had.
