I got the new Dirt Wheels today (april 2007). On the cover is a 4 stroke banshee. It looks like Yamaha is testing some 4 stroke 500cc twin cylinder Banshees in Japan. I just skimmed over the artical and there doesn't seem to be much info. on it yet other than Yamaha is testing many different prototypes. Basically they are saying it is 2 YZF250 cylinders or half of an R1 motor. There is actually talk of it coming out with 60-70 hp out of the box, but may even be as high as 85hp (1/2 of the R1). It will be interesting to see what Yamaha actually does with this. I am wondering about the powerband of the twin 4 stroke motor. Will it have more torque/bottom end power, or be higher revving like a sport bike.

I looked on Dirt Wheels website and they don't have the picture of it and I couldn't find one on the net anywhere. They only show a side view of the quad in the magazine, but it looks like the Banshee radiator with Raptor/YFZ450 front fenders and headlights.

i wanna buy a quad for the days I don't feel like foot plant'n. was looking into a new can-am, but now i might have to wait. That Banshee sounds like a Raptor killer.

I always wanted a Power Wheels 4 wheeler or Jeep version.

was looking on a banshee forum and those guys seem to think it is a hoax

I hope so. Next thing you know Chevrolet will be dropping an I4 into Vette chassis' to lower the price and power to make them more affordable and insurable. Why not put smog pumps on and emissions friendly horseshit. Maybe start making an "alternative fuel" Banshee running on propane getting 49mpg while throwing down a staggering 15whp. :1 If Yamaha ruins the Banshee with that 4-stroke pile of ---- motor, Yamaha will lose alot of customers.

I always did too, never got it though

i read somewhere that 500cc banshee is supposed to have 72hp. if that is so that is far more than the 350cc 2 stroke banshees have now.

very big step up...

Those are just estimates from uneducated people.

And I supposed it "should be" more reliable than the 2 stroke 350 motor, right? It's funny how everybody I know who owns a 4 stroke is having problem after problem and when they first bought it all they could talk about was how reliable and trouble free they are. One of my friends just had his bike serviced after it wouldn't start and was backfiring. $1200 for a "tune-up" and overhaul that shouldn't even be necessary. I've never had an expense over the cost of a new piston/rings and a cylinder hone. 4-strokes suck and putting one in a bike that has been an absolute success as a 2-stroke for so many years in a row would be retarded and pointless.
