Check out the YSR50's rectangular steel diamond frame, full fairing, rising-rate Monocross suspension, front disc brake, and close-ratio, five-speed transmission. And what's more, unlike other sproty bikes of its size, the YSR50 is completely street-legal. Ride the YSR50, and quick glances from passersby will gain you double-takes, for the YSR50 bears a striking resemblance to Yamaha's legendary FZR sport bikes. |
