buying a left over 08 next week

another :lol: for the fofiddy.i'm about your size and weight and just bought a 450f and have had several 250f's also but honestly the newer 450's are within pounds of the older 250's. even on the east coast really tight and technical riding they are much more manageable.....hill climb?what hillclimb :worthy: it's always alot easier and cheaper to tame a 450 down versus hopping a 250 up.you won't regret the 450,especially for only 400 more bucks.....

Taming the 08 Yz450f is pretty simple... Just keep the stock shorty pipe on it and you have one very tame 450.

I would like to see you bench press an awkwardly sized object like a 450 dirtbike. Are you serious? That just sounded strange to me. And you are talking about minimizing risks? I want to see that bench press, I think you need to post some pics!

lol practice make perfect.

and ya i wana see that 2.

:lol::worthy: Yea, that would look funny, but, thats not my point, my point is a 250lb dirt bike is not a struggle for me to manhandle. It would be difficult to actually pull off because of it's awkward shape as you point out, but the weight would not be a challenge. that was my point...

You are right. I have ridden a stock 07 450F, and I must say, it is tame compared to the SNAP of the 06! Has anyone else noticed that?

Yeah me too, I grew up riding big bikes.

That is exactly what everyone was saying about the '06 vs. the '04. :lol:

I just just switched from a 01 WR250 to a new 08 YZ450 and Weds ride made it perfectly clear there is a rather steep learning curve there but I would'nt trade my 450 for anything.

I can only figure they are moving from a 2 stroke power output to a more linear output? Because my buddies 07 does not resemble my 06 at all in throttle response... I can't explain it!

Throttle response, or torque output in the lower and mid ranges? Throttle response refers only to the engine's ability to answer the throttle cleanly without stumbling or bogging.

The '07 has a slightly different cam profile and lobe centering along with a different timing curve, all designed to reduce torque to a level that's manageable without a lot of effort while increasing the peak power. The effort was successful on both counts. When the '07 was tested against other bikes by most of the mags, most of them complained that the engine disappointed them, and then proceeded to turn their best lap times on the Yamaha. The suspension is good, but is it that good?

If you do something other than MX, and want more grunt, or just want more grunt, an '06 exhaust cam will provide some. An MSD or Vortex ignition will help with whatever is missing. But you'll loose up to one HP of peak power.

I'm looking for ways to calm the initial repose down on my 06, I have been working with the G3 throttle tube to extend the amount of throttle range. I would much rather move my low end explosion to the top end of the rev to make my roll on throttle more controllable when looking to hop through a rhythm section.
