Will there be a 450F for sure?

13 posts in this topic

Yes there is a 450 coming and it's roomered that Dr. D rode a 450 at the Glen Helen 4 stroke nat's that was disguised in 426 plastic. A buddy of mine from a popular dirt bike mag says they have pics of the 450 in 426 plastics. Specs are not detailed but the motor is wet sump, frame mods simular to the 02 yz250/125's and the WR gets e-start. Just a thought, if the wr motor gets e-start stock, then the YZ motor will be able to accept the e-start mod as well! It's not the radically new aluminum framed monster that everyone was antispated. But it should be fun.

unless the guys in japan have been hitting the crack pipe often, it will be a different motor for sure. why you ask? because just look at the 2 kits that add electric start to the current motor and tell me that's not insane!

nope, not gonna be like the '02 motor at all.

at least the bottom end won't be.

if ya want a REAL hint at what the motor is gonna look like, look at the NEW motor on the R1 street bike. :)

What really concerns me is if the bike is going to lose some weight. I have an 01 and I'm not trading it in unless it loses some weight. Actually I hope it doesn't lose any weight, cause then I'll add a 250f to the family and buy a new bike each year (alternatlely). :)

I was told that the motor from a distance looks the same, but under closer inspection you can see that the clutch cover is positioned higher in the the cases (to accomidate the E-start) the head & cylinder look sleeker. other than that it's hard to notice many changes to the motor but I am sure there are many. The swing arm also looks to be slightly different than that of the 02. I was also told that Yamaha went to great measures to cut the weight without sacraficing reliablity
