Bubba on a 450F ?

I've heard rumors that the "BIG FOUR" factories have 250 two-strokes that have close to 60 hp, and weigh under 200 lbs.

If it's true, the four-stroke revolution is officially over!

You know they have too...it's just weather tehy want to let poeple know they have them...

that would sink the 4-stroke ship for the pros and you know most would go back to the 2-stroke (we can only hope

)

Actually Brendan, historically it's proven that championships and individual riders winning don't sell bikes. It's tests and word-of mouth that sells the most.

C what i heard on " Wind Tunnel" was that Bubba was going to be on the new kxf 450. I believe that he said that he was but i could be wrong

i havent seen them nor heard of them yet, but that would be sick

heck, even with tech bolts all titainum stuff (takes 2000$ to deck out a bike with ti hardware, saves 9-10lbs)

met/tec has a kit with just front/rear/subframe axles, they say it takes 2.5 lbs off the bike. Along with the rest of there hardware, like you said adam, you can shave 9lbs off the bike easy. I think some manufactures might even have Ti subframes and what-not.

Amagine how much weight a Ti subframe would shave. Along with a carbon fiber silencer like the one RC an Reed have, Mag Triple clamps, Ti head stem, hubs, and who knows what they do to the motors...thats like 15lbs worth of savings.

Ah yes, it's really too bad (yet I agree with it kinda) that the stupid AMA made TRUE works bikes illeagal back in 85'.

Also, Brian, I doubt motors will ever be made out of complete Ti, Ti weaken significantly once applied with heat, engines would be toast in my opinion.

taken from RacerX:
Will you be at a disadvantage in the outdoors with all the other top guys on 450s?
(Stewart)The new 2005 Kawasakis are really fast stock. Rick Ash, he actually built this motor that I canÂ’t even ride right now! ItÂ’s too fast. I donÂ’t think I will be at a disadvantage. I know when the Kawasaki four-stroke does come out, I am going to get on that. I think we are right there. We have power. We are good.

by the way, the new KXF450 isnt the same as the Suzuki RMZ450. their 250Fs r the same, but they did the 450s separatley.
