Yamaha's entry level GP bike. Great handling but the engine let it down when comparing to the RS125 Honda.

Fast and light and some say better handling than the Honda.

The early engines had the over square design and did lack from not enough midrange. The later square engine from 1998 improved things but with the long development history the Hondas had it was still difficult for the Yamaha to catch up even though there were a few riders that did quite well on them.
