I had a '98 EC250 and that engine was smooth as butter. The counter-rotational mass took away the "hit" making the bike easier to ride in snotty conditions. GG did away with the counterbalance shaft in '99 and improved crank balancing.
Forks are 45mm 'zokes. One side adjusted compression and the other rebound. Strange, but it worked pretty good for off-road. You either needed to get the sliders hard-anodized or change oil frequently.
