i have an '05 honda trx 450r, i got on ebay for like $60 shipped, it mounts kinda like the 400ex, but has a bigger resivour thats offset to the kicker side, i had to lose my mounting tab for my rear fender near the air snorkel, which also had to go, but it rides like a dream, and only raised my rear like 3/4", unlike the yfz 450's they make your assend about 3" higher, too much for my likings < higher center of gravity and just look plain silly imo
