i havent ridden much else, but i took my shee to a mx track and it was not that hard to handle, even with it completely stock. i could control it in the air and make the landings pretty smooth, it was just hard if i came up short which happend a few times cuz that day it was having trouble shifting to 3rd. they definitly take some getting used to tho, first time i rode it i felt like i was riding a car compared to the blaster, but now i can throw that thing around easier and it is more predictable then the blaster was.
also z400's i heard arent all that great except for on trails so you wouldnt be dissapointed with a banshee.
