| Yamaha's profilation of this bike |
| The Revolution Continues... Not so many years ago they would�ve locked you up for suggesting a four-stroke single could spin to 13,500 rpm and produce a broad torque band the whole way there. It would have been unthinkable to conjecture that such a machine could win back-to-back AMA 125 Supercross Championships, not to mention a slew of magazine shootouts, including top honors in Dirt Rider, Motocross Action and Cycle World last year alone. |
