from what iv seen, a banshee with pipes is a good match for a 450 with a pipe. this was an 04 yfz. i think the new ones are faster but :shrug:
on pavement the banshee would have the advantage and on dirt the yfz would win. both skilled riders, fresh motors......
i think the new 450s are faster than the old ones, thus faster than a banshee
but whatever, IMO a banshee is more fun, feels faster, gives a better adrenaline rush when you hit powerband :thumbsup:
