2-strokes might have ruled the 70's and 80's but lurking around the corner were some rare and incredible custom 4 stroke mx bikes. For example, the famous HL500, or the C&J framed custom Honda's by Bill Bell. We've used the "Thumperbird" in a few apparel pieces throughout the past to honor the mighty 4 stroke race bikes of the 70's. And now we're bringing it BACK. And it won't be the last time. 

The perfect fit will make sure you feel straight-outta-the-box awesome. Wear it in the pits, rallying, racing, or just cruising on your vintage motorcycle.
