Kawasaki finally put all the specs out on their website of the KFX450R this morning. What do you guys think? Yes or No?

The only thing they still haven't released is the price.

I am sure not all that happy with the specs. It looks like you need shocks and arms right away and it is tiny so, so much for any comfort.

OK here are the specs...

Dimension Kawasaki Suzuki Honda Yamaha

Length 71.1 72.6 72.6 72.4
Width 46 49 46.3 46.1
Height 41.9 42.7 43.1 42.9
Wheelbase 49.4 50.6 49.2 50.4
Seat height 30.9 30.7 32.4 31.9

Weight 365 350 350 362

These are all claimed specs, and when you look at them, the only real big dimensional difference of any of them is the LTR's width.

if the kfx450 has an aluminum frame, wouldnt it be lighter than the rest?

It just looks average on paper. All the 450's weigh in at 375ish gased and ready to ride. I like to see a translucent overlay of each quad together like the magazines do with street bikes. That way we could see how the seat, pegs, and bars are diff on each, not to mention geometry.
If it turns out to be roomy like the 450R, then I'd buy one. I like Kawi's contencengy program for this year.

The frame is 20% lighter. But the added weight of reverse evens it back out. Remember the none of the other 450's have reverse. Also the trx450r is like 354 lbs for the kicker. The e-start (equivalent) version is 363 lbs dry according to honda's specs. So for 2lbs you get an EFI system & reverse.

The only thing that seems dissapointing.. is it doesn't appear that the front shocks are going to be fully adjustable. They look like they might be preload adjsutable.. but maybe even not that. Rear is fully adjsutable.

Or also, If you think about, with the removable lights and fenders that it allows you to do, that can save more weight as well. But I'd say there's still a great trade-off. A couple lbs, for Reverse, and F.I. Some people are saying they are worried about the frame busting. A whole new frame in a first year production race quad. But in Kawasaki's pictures there is a guy jumping pretty high on it. I think if there were problems they would have been figured out. I think it's going to turn out to be an awesome quad. I hope I can end up getting one.

Your statement about the frame being 20% lighter is not accurate.
Kawasaki says the frame is 20% lighter than a steel frame WITH THE SAME RIGIDITY. This is not the same as a being 20% lighter than a steel frame.

As with the Cannondales and the short run of LRD Attitude Aluminum frames, Aluminum frames are inherently stiffer and more rigid than steel frames... UNLESS, you add so much extra material to the steel frame to match the rigidity of the aluminum frame.

For instance, take a stock z400 frame and an LRD Aluminum frame for the z400... there is no more than 1 pound difference in weight between them. The aluminum frame is much more rigid however... but what about aluminum frames being lighter?

No one knows... but I would bet that the Kawi frame, though aluminum, isn't much lighter than a stock frame from red, blue, or yellow.

I understand that. It weighs approximatly 20% lighter than the equivalent steel frame. I didn't say the frame was 20% lighter than a 450r frame. I just said it's 20% lighter. It's definatly beefy.

But on the same hand, if the frame weighs the same as the competitions steel frames.. they reverse gearing, wiring, sensors, efi, fuel pump, filtration, etc.. all weigh less than 3 pounds.

The reverse mechanism on the 400ex added 11 lbs to the quad. (2001 was 375 lbs. 2006 is 386 lbs.) 450r e-start weighs a claimed 6 lbs more then the kickstart version. (hard time beleiving less than 10lbs since batteries weight 8lbs)

I'd bet the aluminum frame is 5lbs lighter than the competitions steel frames.

Edited (12/21) to fix my bad math.. LOL.

Yeah the specs are ambigouous at best; the front shocks seem to be fully adjustable though. Take a look at the pics, you can clearly see an adjuster on the ressie (compression) and the lower part of the shock (rebound).....They may be something else and they may be different by the time they are released but in the pics it looks like the goods.

And.. I relooked.. not sure how I cam up with that number (dyslexia? 368 to 386? .. lol). 30lbs did seem excessive.. lol. But there is at least a 10lb difference. The batteries weigh 8lbs. Starter at least 2, not to mention extra wiring and brackets.

Now.. tell me this.. how is the 2007 450ER 350lbs.. and the 2006 450ER 363 lbs? There were no significant changes. I thik thier numbers are wrong.

In fact the 2007 450ER (http://powersports.honda.com/atvs/sport/model.asp?ModelName=TRX450R%20(Elec%20Start)&ModelYear=2007&ModelId=TRX450ER7) is claimed to be lighter than their 2006 450R (http://powersports.honda.com/atvs/sport/model.asp?ModelName=TRX450R%20(Kick%20Start)&ModelYear=2006&ModelId=TRX450R6) kicker.

The specs obviously have errors.

Do you guys think so far that the diemensions released for the KFX450R are a good setup compared to the other 450's? I've always been a KAWI man for everything, I just want to make the right choice when this quad hits the dealerships.
