Here is a clip off Highlifter's website about Scott's Foreman 550 with 28" front & 27" rear Vampires:

"In its July 1999 edition Dirt Wheels Magazine posed the question “Is this the World’s Baddest Honda Foreman?” We haven’t seen all the others so we don’t know for sure, but we have yet to find one that will beat this one in the mud. In fact the only thing that comes close to hanging is a Polaris 500 with 16 inches of ground clearance (under the entire ATV) and 28” Vampire tires, performance kit etc., etc. It also belongs to Team High Lifter. "

I want to ride it!
