When I had mine and was asked that question I just told them no it is a replica and not even close to being the same as an Original. I had the wrong roll bar, side pipes, brakes, and wheel base. But I also has everything matched on the dyno and the side pipes I used without the 4 into 1 collectors gained me 13 horsepower. Even when I told them it was just a replica, I would guess that 90% of the comments were very nice. I just figured as different as mine was from an original, if the ones that got nasty about it had to ask they never knew a lot anyway.
