I think that it must be a universal experience when building a bike to have a bunch of big parts all ready to go, but be held up by little things. I can't really sort out the seat until I have a tank. I couldn't really sort out the tank, until I knew where the bars were going to be. I couldn't do that until the fork was done, and arguably should wait until I get a front tire on. I was reluctant to buy a front tire until I knew how big my rear tire was going to be. And my wife was slowly catching on to how much $$$ i was spending on my $400-bike. That said, I pulled out a 140/80 dirt bike tire I had lying around and wrestled it onto the rear wheel. Surprisingly, it cleared the swing arm! That means I can have a 120/80 on the front (awesome!), and I felt like I had enough of an idea where I was going to find a tank.
I don't entirely dislike the original MT tank, and I really like the original silver/orange/black color scheme, but when I look at all my inspiration pictures, they seem to share in common a bulging, crotch-rocket style tank as opposed to the 1970's-era tear-drop tank. It has been a challenging to know where to sprinkle bits of modern parts and where to retain some vintage soul. I love the forks/wheel/rotors, but I thought that now I needed some counter balance, otherwise I'd have a old frame with a bunch of modern stuff on it.
So here's my argument. See if you agree. I think this tank is the vintage version of the new crotch-rocket style tanks. It is humped up in a similar way and has the indentations for your knees.
Additionally, it's just plain cool. Bonus points for being Honda.
