I just wish they'd hurry up and release them. Thanks for the vid Rickk. I'm with you Grayracer, I wish there were more tracks like that around here. Tight technical tracks are an epidemic in New Mexico, I hate em, but the mini-dads love them, and that's who the track owners listen to. Sorry to get off topic.

it would be interesting to see a dyno of the DRD because I was just looking at the DRD on Langstons 2010 at Starwest 30 min. ago and it does not have a loop in the header , it goes straight from the exhaust port into the muffler like the one Doug was running at the Vet National , seems pretty short compared to typical pipes

The picture Dr.D has been running in the mags and currently on mxa's website shows the loop in the exhaust. I wonder if he is running something different, I can't imagine that that would be a long enough header.

My new 450f just arrived it is still sleeping in the box at Prince George Yamaha. Only problem is I now have to wait until spring to ride it. I am gonna have a great winter doin' up my graphics and blingin' it out. Can't wait until next mx-season. It is always us guys in Vet class who have the best rides.
It is so funny, when the my guy at the dealer called, my wife was gonna blow off his call, and say I was busy. I was. But then she realized who it was, and called me to the phone. It was like the announcement of a new baby in the family that we have all been waiting for.
Other-than having to wait until spring to ride it ( I'll stick to my 250f for arenacross in the winter), I am so happy.
One thing fellas. Should I add more grease in a few places? And if so, where?

I always regrease the linkage and steering stem with Bel-Ray waterproof grease. It's a hassle but it pays for itself in the long run. Congrats. Still waiting on mine....

Damn! If you read Dirt Bike mag they say the Kawasaki is the most powerful 450 around. These charts shurely don't support that "opinion".

Makes me wonder if Yami and Akrapovic don't have a little "understanding" going on.

Most powerful does not equate to the most rideable...............

Unless they ran a chart of their own, they wouldn't really know that. "Butt dynos" are notoriously inaccurate, and would have told you that the '03 YZF was more powerful than the '06, when in fact it was almost 3 HP down on the later bike.

I wonder how the FMF pipe would be on the 2010? I know on 2-stokes they made alot of difference.

FMF has a 20% off all 4-stroke pipes until like march I believe. You can get a SS muffler and midpipe for like $279.00

Yeah, I know. The point is Dirt Bike makes a big deal about THE POWER of the KX, not how ridable it is.

And obviously they wouldn't KNOW that unless they did a dyno comparison of their own. Duh. The point is they emphatically call the KX the most powerful of the 450's.

Jeez, lighten up you guys. It's just an observation.

agreed


I agree also but the pipes just seem to look so good on the bikes and to me seems like they smooth the power out.

Rickk...just curious what skill level do you ride/race and how much do you weigh and height

Thank you for the honest review....

Different pipes do different things to the power curve. I think it's wise not to run out and buy the first pipe that's available for a new bike. I'm going to wait until everyone is in the game before I spend any money. Also you have to know what you want and what kind of riding you are doing. Some systems are designed to really focus power in a certain area of the curve. Yamaha designed the 2010 YZ450 to have a lot of low to mid power. You might not want to buy a system that further inhances this trait if you are going to ride big outdoor tracks with many high speed sections. Pipe shootouts are great sources of information. Another thing you have to watch out for is dyno charts like the ones on the Akrapovic website. Unless all the bike were tested in identical circumstances (humidity, temperature) those numbers shouldn't be treated as 100% accurate. My point is there are a lot of factors that can influence those numbers.

so I also rode the 2010 YZ450 today (not my bike). Not that it matters but it was the white model. Very nice looking bike!

Keep in mind my current bike is a 2005 CRF450 so I base most of my comparison to my bike. I'll agree with rickk, the bike absorbs landings nicely. On hard flat landings the bike would hit and be ready to go immediately. I was very happy with the ergos of the bike. I'm 6' 2" and the bike fit nicely in stock form. I did notice the shifter was not were my left foot expected it to be (as if it was too short compared to my CRF).

Turning was excellent but again, I'm comparing this to my CRF that hates to turn. I would need to re-learn turning on a bike like this. The bike felt only slightly lighter than my CRF. Jumping was what I would expect, basically no weird traits. Power is very nice: smooth roll-on, no hard hits, not touchy. I didn't get out of 3rd gear and I could tell if you needed the power to climb etc. it was just a small rotation away. Again, my current ride is non-EFI so the '09+ bikes make a big difference to me. I thought the braking was just fine...for me anyway.

When it comes down to it, the bike did very little wrong for a guy like me. From the immediate gratification of comfy ergos, smooth but powerful delivery, excellent suspension...I could not wrong the bike......unless price is part of the discussion. At the current out the door price I'm hearing about, I would have a hard time justifying the purchase.
