Does anyone know the weight of the kfx450? Width, Suspension travel, etc...

Posted by: Ruby Soho

i don't think they have been released yet

Posted by: DESDAK4

Nope, the specs aren't out yet. I guess Kawie wants to see how wound up they can us.

Jay

Posted by: banshee84

I figured. What are your guesses as to weight?

Posted by: DESDAK4

My guess is in the 350-380 range just like the other 450s.

its got a aluminum frame though.....

Posted by: DESDAK4

I'm just taking a stab in the dark that with the aluminum frame and then reverse she will come out right about the same as all the others.

im guessing anywhere from 320-350

Posted by: roundsy

i im think close to most of the other 450s, maybe a tad bit lighter so anywhere from 340 to 380lbs

Posted by: JMaN05

even though kawie and suzuki are no longer together, kawie is follwoing in suzukis footsteps. showing us little pics and making us wait so FU$K!NG long to see the thing and get specs! i remember the commotion over the LTR, now this thing...damn! at least with the YFZ and 450r, yea there was the anticipation, but the people werent too excited because they didnt know what to expect. but now all these companies are stepping it up and trying to beat every other. now that kawie has to beat suzuki somehow, and it doesnt look like width(MX) to me, they may just be going with a faster, FI version of the YFZ/450R(a mix of each). all in all, trying to please everyone! an all around great mechine, like may i say, my favorite, the YFZ450.
thats a wrap

Posted by: JMaN05

on another note, if the new KFX450 isnt as wide as the LTR, i would expect to weigh less(under 380). taking into account the aluminum frame i would say 8-10lbs less(370). looking like the others(YFZ/450R) and looking to have electric start, i would say thing thing weighs about 340-345. espeically since Kawie is trying to beat out the compeition.
and if it does infact have a reverse gear, i would say it would be 360. which still isnt bad for a 450cc, FI, sport quad with reverse

15 lbs added because of reverse?

Posted by: JMaN05

do you suggest more or less?

Posted by: D6MX450R

haha I'm not really sure but 15 just seemed a bit high.

Posted by: JMaN05

D6MX450R-im in northeast PA

FQX Ryder-you have to keep in mind the extra, reverse module, some sort of switch mechanism to get it into reverse. i think 12-15lbs is a pretty good estimate on reverse add. when Polaris added reverse to their predator it added approx. 11lbs.

Actually it was only 3lbs. The 04 Pred was 412lbs and the 05 with reverse was 415lbs.

Posted by: JMaN05

i acutally meant to say 13...but i must have read it wrong. thanks for the correction. so maybe reverse will only be like 3-5lbs more. that would be nice for all of us.

Posted by: GE4x4

No problem. I think it's great for a 450 to have reverse. I remember I read a interview with Yokley and he said his only gripe about the new LTR450 was it didn't have reverse.

Posted by: bwamos

2004 400ex was 275 lbs. (no reverse)
2005 400ex is 286 lbs. (w/ reverse)

Granted they changed the plastics in the same year.. but I doubt the plastic change added 7 or 8 lbs.

So 10lbs is about what they added with the reverse on the 400ex.

Posted by: iwannaride202

do you know the exact cc's this thing has......like is it a true 450???????????????

Posted by: Dale512

If it has the same bore and stroke as the KX450F Dirtbike then it will be 450cc. As for reverse, it adds 5lbs max, probably closer to 3.

As for the 400EX getting reverse and gaining 10lbs, Honda is good at that look at the difference between the 05 & 06 450Rs, the kicstart is 7lbs heavier for 06 than 05, but I see nothing that would have added weight, if it anything it should have lost weight. Maybe the original weights were alittle underrated on the 400EX & 450R? Just my guess I would say 370lbs MAX dryweight for the KFX450.

Unless I missed it, something that hasn't been mentioned yet that I want to bring up is that the dag-gone swinger better have a Honda style, concentric chain adjustment!

Here's a question I don't know much about: If the chassis needs gussetting, being aluminum, will that be a problem? And for the Cannondale guys, did those chassis' need gusseting?

A kick-start option would be very nice, such as on the the LTR and YFZ.

It would be nice if the a-arms were aluminum uppers, like my YFZ. I'm fine with stock width since I'm a trail rider. I wipe out big time, and since the stock YFZ a-arms are so light and relatively easy to bend (when subjected to abnormal forces) they provide a buffer to the frame. Meaning, you want the a-arms to go before the frame bends or gets damaged! That's also what contributes to light weight.

Between a kick-start option and some Fox Floats... there's a weight savings of 10 to 15lbs IMO for the weight conscious.

I cannot wait to see this bike! I may be riding green in '07!

what ever it weighs I can always hit the gym and make it lighter

Here is a trend I noticed.

Observation #1 Super bikes- Suzuki and Kawi have been at odds over crotch rockets for years. Kawi just beat the Huyabusa 1300cc up side the head with there new 1400cc super bike this year.

Observation #2 Dirt bikes - Suzuki and Kawi again are duking it out. Kawi has a killer 250 4 stroke and Suzuki gave there fuel injection to the quads first (which struck a nerve in the dirt bike world I'll tell ya)

Odservation #3 Quads - Kawi was just waiting, more than likely knowing that Suzuki was putting together a killer race quad with F/I and all. They did there research, waited, bought a few of them, tore them to the ground (like all the R&D guys do) and said.... why not slap them in the face one more time ((just to spice things up)) Than put together what most people want. Light weight, reverse, electric start, and the new and awe insiring Fuel Injection. Plus notice how the engine compartment doesn't have the ugly black box and pump surrounding it.

Have you noticed quads are not staying the same year after year like they used to. Yamaha bumped cc and ergos. Honda resonded to the riders wanting electric start, adn gave the 400ex a make over and reverse. Zuki steps right in the middle of things and builds a purpose built racer. How does Kawi top that. V-force sales aren't enough, and the KFX400 is way outdated.

We haven't even heard all the specifics yet but I'm sure the quad they come out with will hit zuki hard. Follow the trends.

If it does need any type of gussetting, that could be a downfall, aluminum is pretty hard to weld.

But it should be fine, crosses fingers

Posted by: Grcman

mayby there is a reverse option like the 06 450r's with the electric and kick start

Posted by: Sandgod4

Cannondale may have done alot of things wrong, but the frame was and still is the best frame ever made to date..

Posted by: JMaN05

the only thing i dont like about that cannondale aluminum frame is the oil being held in it...i mean, i guess its a good idea for proper weight distribution and such, but weird to me..

My buddy had a Suzuki DR350 that held the oil in the frame.

Posted by: trx4ever

all dirt bikes hold oil in the frame

Posted by: JMaN05

no, all of them dont.

maybe the 450's. i dont think they do though...but then, where does the oil go when you make a hybrdi and have no hollow aluminum chassis?

Posted by: Tri-valleyracin

an oil tank is just a thought!

Posted by: JMaN05

well if you are familiar with hybrids, the yzf engined hybrids have an oil tank because thats what the engine uses. and for the CRf, there is no oil tank. the bottom end holds the oil. i was trying to make a point about aluminum chassised bikes, i know about hybrids

Posted by: cdrookie

1 reason to have oil in the frame is to dissipate heat(aluminum frame that is), another reason was to keep the crankcase size down. the bad part is that if the motor blows getting all the tiny particals out of the frame is a pain in the arse(if it can even be done). it's nothing new, even bikes from the 70's had oil in the frame.

Posted by: GPracer2500

Buell makes a street bike that hold its fuel in the frame and the oil in the swingarm. Strange but true.

sorry kraz but I totally disagree with that, aluminum is NOT hard to weld,only for those who are not experienced at it, I personally am not but I certainly know many that are good at it.such as Cannondale,they are masters,and I mean that in the truest sense of the word,I am a former roadie (cyclist) and own a team Cannondale CAAD3 R400,It really is a work of art.A very good friend of mine is certified to do welding for Government work tells me that in the right application such as moto cross bikes and ATVs it's a great choice.We can all be sure that when we get a good look at this thing it won't be a let down like the long awaited showing be Yamaha of they YFZ,oil squirter,new colors and renthel bars,what I let down.

this may be a dumb question..but... how does an aluminum frame hold up...even with gussets. it seems like the whole frame would just crumble when you land a jump.....?

Very Very strong, most dirtbikes have aluminium frames, they seem to hold up very well. Also, the Cannondale quads have aluminium frames, they're very strong too.

Posted by: CHEVYZ

Aluminum frames are built very strong!

Posted by: velocityatv

Not that they are built stronger or are made of stiffer material.

Chromoly (steel) is lite, strong, and will bearly flex.

Aluminum is lite'r', may have less strength. But it makes up for it in flexability.

If a metal can't flex it cracks. Aluminum can flex more than Chromoly. The only problem it runs into is that it can flex too much!! That is why it is all about design. You want it to flex but go right back to the same spot it was before you came up short on the triple, or slid sideways and hit the stump.

Aluminum is the wave of the future, they can use super top secret heating methods, crio freeze it, cast it, even make julian fries.

Its a good move

wow...thanx for the info guys...i learn more on atvriders.com than i do in skool!

495 cc is pretty good for the KFX 450. the thing that i dont like is they arent telling the specifications on them and i want to know. I think that they will be the top 450 out there for 07. I just cant wait until they come out to see more about them and how they run,so if i should get one or not.

Specs were released a couple days ago. Recheck their site.

Small gas tank just like the yfz, hope none of my friends switch to the kfx. I have 2 friends with yfzs and we have to haul extra feul in pop bottles so they dont run out of feul when we ride. Looks like the same thing with kfx.

Posted by: Anpo

nice :P :P

regards, Anpo

Posted by: WILSONatv

then again the kfx has efi and the yamaha doesnt
so i think that would play a factor in it

Posted by: dirt286

yeah but the LTR holds the same amount of fuel and is also EFI and that thing is a pig on gas compared to my honda
