Ultimate - Another excellent rare Yeti Ultimate - this one with the original Yeti/Answer Accutrax rigid forks, and Magura Hydraulic brakes.
Softail - This was Yeti's first attempt at a full suspension bike. Travel was minimal, two inches or less, and I don't really know if it was called "Softail" or not, , but that's the information I have. This was the bike to own if you wanted to win the Kamikazi at Mammoth mountain in 1992.
Softail - This is the second evolution of the bike above. This one has Pace forks and a pretty freeride-ish high stem and riser bar. My thanks to Johannes from Germany for this pic of a great bike.
Lawwill - I have to kinda laugh at this bike. You probably recognize the design, it's the Lawwill rear end from the Yeti/Schwinn Straight six/eight (Schwinn owned Yeti at this point). Except it only has 4 inches of travel, which is nowhere near adequate for DH racing today. It's probably a great bike to ride though - except for the fork.
Lawwill - This one has 6 inches or rear wheel travel. And a pretty serious Foes fork. Probably a pretty decent DH bike.
