We have a zilla in our area that is faster than a 686 on nitrous, a yfz 470, a couple of 310 and 330 pv R's and many built banshees. It is of course slower than the drag banshees, but its not a drag quad. It's main competition on the hill drags has been a crf 450, but the zilla is typically quicker. This zilla is setup for flattrack and has been the reigning AMA district ice champion for about 3 years. It tears it up on big tracks but the yfz and crf (when its not on nitrous) have an edge on it on these tracks, especially the short ones.

Another zilla is setup for drags w/ drag pipes and swingarm but is consitently running very low 5's on the sand drag. Our track is slow from what I hear, but that zilla is not all that impressive. Which is understandable seeing as how the same guys focus on thier custom built drag machine with a triple cylinder polaris and a big bottle of nitrous.

They are out there, but very few in numbers and most are fast but not all that impressive when competing against other purpose built machines.

 

I agree Mark, but when does the point come where you can honestly say "It's still just Raptor" or "It's still just a Banshee",etc. IMO the fast bikes are the ones can be ridden all day then line up and do some good running too. It's all in what you want I guess. My wife's R and my Banshee run respectable times, but are at the point where driveability is going to give to go any faster.
