Just wondering. There's been rumors that YZ150Fs might be in the works for racing in the 85cc class. Seems like Yamaha should get one out there since Honda is stealing all the thunder lately. The XR50 and CR150 (motard) crazes are a boon for Honda for sure. But, if there was a race-ready mini 4-stroke I'd buy one for a play bike for sure! You know, long travel, similar high-revving engines as the 250F/450F etc. I'm not too interested in the BBR creations but would love an off-the-showroom-floor mini-race-thumper! I think it would spark even more interest in adult play-bike classes. Anyone know anything?
