    There is no absoulte top speed for any machine due to climate, elevation, jetting, etc....

    But it should be around 68-70 mph. stock.

    108 KPH is only 55-60. The YFZ450 should do 120-125KPH I'd think.

    The new 450's are slightly slower on top than a raptor (like 3 or 4 mph), if you have ever ridden a raptor, you would know that that is pretty fast.

    Is it true every 1000 feet you lose 3 horsepower?

    Once me and uncle arlis took our YFZ450 up to 93 miles per hour. then we drove it off a cliff and the thing still ran. then we ran each other over with it. man was that thing fun.

    Everyone seems to be sensitive to these types of post...Myself included...I responded out of genuine curiosity though for this particular bike.

    It would be nice to have an unbiased cut from every thing out there....I guess it takes the mystery away if those type things are published? Cars don't have a problem keeping track and publishing HP & Torque ratings.

    Look at the Mustang / Vett line up...Past years the Stang and the Vette have kind of taken two different paths, but for years it was Ford VS Chevy or the Firebird / Camero VS Mustangs. You don't see anyone trying to put a cap on HP rating for vehicles. Hell you get cars off the showroom that approaching 400hp+. OOOOOOOooo that's too much HP...lets get a bunch of lame dicks to sign this petition and well make Dodge quick making the V-10...Ahhhhhh what gives?

    Anyway I’m back now…I trust a calibrated radar gun….anybody got one?
