    By lack of discretionary money, the industry is evolving towards the “do it yourself” Build your own bike or no ride.

    Reminds me that I never understood why motorcycle manufacturers still feel the need to build gas tank with big openings to fill up. The size above is enough. So why?

    Awesome. Lowbrow has some great stuff and it’s geared towards people that actually want to build, not just bolt on.
