These may be the only items that Yoshimura makes that offer no objective functional advantage, but sometimes cool is its own reward. And the retro Yoshimura R&D of America t-shirts with the retro “Pops” Yoshimura images are simply cool beyond words. They evoke a simper era when the engine builder was the guy who made the bike go faster, and traction control was accomplished with the rider’s right hand. Hey, if they can do that, maybe these shirts are functional after all. Suggested retail for Yoshimura’s 2012 casual line starts at $22.95.
