Where did they all go ?

I guess these Rotax race bikes are just "new enough" they're not considered vintage.  They don't really have a good class for these right now . . . but it's coming.  At the Viking meet a guy had a complete Rotax with Knight frame with wide 35mm front (motor was out).  You got the whole bike, 2 spare wheels, a spare engine(that just quit one year, electrical he said?) and a running motor(tired)with a Scott head - all 600cc with an extra carb and a couple tires. $1,500
