The Banshee only weighs 10lbs less then the Raptor... I would say that it's really light. The 450's are even lighter then the Banshee's are...
Don't listen to the BS people say... Tell him to put up, or shut up... You won't win a race by asking a bunch of dudes on a internet forum if you're bike is faster then you friends... and you'll never know who's faster untill you line up with him.
Please look around the forum next time you start a topic... you would have found 20 other topics asking the same question... and you would have found the same answers.
Now... Get out there and race that slow poke.
