The WR500 is pretty rowdy for the street. It does NOT like to cruise at one speed: It stutters and rattles and complains. I think a flywheel weight would be very helpful and I'm looking into it. The FMF Turbinecore muffler is also quite loud, so I might strap on a DBsnorkel to help reduce the sound. It is, however, quieter than the Harleys that drive around town!
