I have a stock banshee I bought new in 2000, the only mod is a K&N filter and no airbox lid, The rest is bone stock, including the gearing. I am running 21-12-8 haulers and mohawks on it. Removed the heel guards and front bumper, thats it . I have raced it against all the new four strokes as they have come out and this is what I have found:
400ex or equivelent- not even a race
raptor660-easily beaten,even if theyre piped or whatever
raptor700efi-closer but can still pull it up the hill (my buddy has one with pipe and rev box-still walked it)
DS 650-easily beaten but faster than 660 raptor
yfz450- these are fast, raced 5 times same guy and got out run 4 out of the 5 times, these are the first 4strokes that run.
450r-have not been able to line up a stocker yet, my buddy has one with a big bore on it and 12.5 comp ratio, he outruns me handily, I would like to see a stock one cause the are supposedly slower than the yfz.
suzuki450- I have only seen 2 riding around so far out there and havent lined up with one.
I weigh 225, so I am not some skinny kid on it either.
These races were in sand up sand mtn in Utah.
The only wild card is what mods they have done, pipes, etc on a raptor are not a problem but I have seen some on nitrous that look stock but are pretty damn fast and I am not even in the race.
