Yes it is. There are plenty of pics out there of the #39 bike.
On the new stuff though, generally it is sometimes better to keep it out of sight for a while, it may get copied extensively later on anyway, by others..
It is really neat though to get an explanation of the how and the why of building something.. on the 39 bike we actually saw the original napkin drawing he did as he thought it up while on a flight somewhere.. and another drawing on the wall of it in yellow , which he did to decide if that was the color to use.
I saw the bike run both times at Bonnevile, but it is pretty loud indoors..lol..
Sure had some big-assed throphies there..LOL..
