My Buddy i ride with has one and 80% of our riding is at the dunes and WOW every time he goes he is Usually the fastest bike there next to the 400+ horse power sand rails he has beat every Bike, trike, quad he has lined up against except his little brothers YZF 450 it climbs faster than any water pumper ive seen all he has done to it is a CDI box intake and exaughst. and yes it does have wings off like a little 4 foot kicker he will get atleast 20+ feet of air thats up not out. the only problem with them is they are Very uncomfortable to ride all day the seats kill you the hole bike is just Small i couldnt ride it be cause i cant turn the handle bars all the way cause my legs are in the way 6'5'' 230 and yes there max carrying capacity is like 220.... so i bottom it out quite easy

The local ATV shop's owner has a YFZ 450 and he brings it mud boggin too. He has had everything possible done to it retarding the cam a tooth, even bigger carb, and thats about it since they are already race ready. He runs like 120 octane in it too. He clocked it on an airport runway at 93 mph at 3/4 throttle and had to let off because it was getting too wobbly.****** fast!

They have a redesigned YFZ450 and the 660R is now a 700R EFI.. You might wanna compare the 2 YFZs before your purchase...
