A busted tachometer on a thumper is a bad thing. The SR500 engine revs hard and quickly, and it can easily get into the red if the rider is distracted by scenery flying by. But the sound of this vintage Yamaha single can be quite mute, meaning a fully functioning tachometer is necessary for safe operation. Mikes XS carries a variety of SR500 tachometer options with black or white faces. We also stock SR500 tachometer cables.
