kx100 power?

[sbg]

I am looking to get my girlfriend a sand dune bike.  She weighs 113 pounds in my favorite outfit, and I am wondering if the 100 will be enough stank for her in the sand.  
 
How do the kx100's compare to the 80cc bikes in power?
 
Thanks.

I have never ridden a 100. I think a 100 would be ok for her. BUT has she ridden before? Not only that has she ridden a two-stroke? I must add this too the sand is very hard on smaller bikes. Have you considered a crf 150 or one of those odd size 4 strokes they are making nowadays. hmm kdx 200 if you want a kaw!

Agreed on the KDX200. Kx 100 could be a little snappy. The kdx would be more durable for sand work. Also can be lowered easily enough to suit her height.

Both are great bikes.  I'm a big KDX fan, but I am considering a KX100 for my wife. The KX100 with a steahly flywheel weight make for an excellent girls bike.  It has the advantage of being almost 100 lbs lighter than the KDX200 and is close in hp. If she is tall enough, the KDX would definitely be more durable. Cam.

Thats where Im coming from too.  She is 115 pounds and a kdx200 is @ 220.  that would be like me riding a 425 lb. dirtbike.  Ouch.
 
I am also a fan of the kdx but as mentioned it is a full sized bike.  The kx100 packs the biggest punch I can find one step below full size dimensions(125).
 
I hear what your saying that sand will stress the smaller motor, I thought the kx100's are powerful as heck though?

[KXcam22]

I have to ask how much can a 115lb girl can stress the bike in sand?  It it was a heavyweight like me maybe but I would suggest that with her the bike would handle it just fine.  You likely will have to swap tires if it is real sand. It would take her from zero to hero just having some decent soft terrain tires on there to boost her confidence .  I know the steahly flywheel weight adds quite a bit of lugability to the engine and V force can bring up the bottom end power.  I was looking at an '05 at the shop a few days ago. Amazingly light and comfy bike. Also keep in mind that the RM100 is the same bike. Cam.

How much can 115 lb stress the kx100 in the sand?  That was/is the question I was hoping to answer with this thread.  I am unfamiliar with the kx100 and the power it makes and wanted to determine if it is enough, or if I should be looking for something more.  From what Im hearing so far, it sounds like that will be enough power for her.  
 
Thanks for the RM tip, I didnt know that.

Sbg,
  I was researching and it makes 24hp.  Not sure what a stock KDX makes but I doubt it is much more than that.  Heck, that's probably more than my first 1974 250 made.  My wife has an XR200. Really nice bike but has a mere 14hp and weights 240lbs (you'd never know it to ride it - it's fun).  It takes at least $1500 to max it out at 24hp (that the KX already has) but is still an astonishing 120lbs heavier than the KX100. The last KX100 I rode was light, nimble, had great suspension and was quite powerful. I haven't personally tried the flywheel weight, but I read an online article where they were making one into a girls trailbike and it sounded like the ticket. I don't see how you could go wrong. Hope this helps. Cam.

Nothing less than a 250 will do in the dunes!

You said it all.

Will do what?  Be way too big and heavy for a girl 5'4".  
 
Nothing less than 400 lbs is worth bench pressing...

[Danger4u2]

KX250 dry weight 213.9
KX100 dry weight 149.9
                        =  64 pounds more for the 250 and more than twice the horse power.

If she's an experienced rider put her on a 250 for sure.
The thing I have learned about horse power is you can never have enough. It's like having a gun, just because you have it you don't have to use it. Same with horse power, it's there when I need it, I don't have to use it. I ride at Little Sahara State Park in Waynoka Oklahoma. My K5 will climb all the dunes with no problem. I see lots of 250's bog down right before the top. That's lack of horse power.
Check out Little Sahara in Okla. thru the dune guide below.

Let us know how it goes.

With flashearth scroll out till you see the U.S. go over to Oklahoma, scroll over the Northwest part of Oklahoma and look for Woodward. Little Sahara will be a little East and North of Woodward near Waynoka, North of State Highway 412 on S. Hwy. 281.

 My friends and I will be riding Little Sahara on 10/27/05 thru 10/31/05. If you or anyone else can join us P.M. me.

the 100 will be perfect. i got my ex a 100 about 21/2 months ago and other than a new crank bearing(i new it had to be replaced after i bought it) its been awsome for her. She weighs about the same.  For a small girl still a novice i found i had to lower the triple clamps on the forks about an inch until they were about a half inch away from the handle bars really made a big difference. At first she was sketchy on the bike but now she asks me to go you wouldnt think lowering it would cause that much change but for her the security of not having to be tippy toed  but on flat foot is a big thing. I warn you about goin bigger than a 100 cause a heavier bike with more power will most likely turn her off cause of fear and if not the first will be harder with more wieght and speed behind it.Also getting her good boots pants armor and helmet and gogles and gloves are a key thing for 2 reasons protection and if its nice lookin stuff (cool s**t) she'll wanna go even more. trust me

Widemouth, I couldnt agree more.  Part of the deal here is getting her a bike that she will be comfortable on and will inspire confidence rather than some 250 that will be big, akward and scary for her.   You make a good point about the gear as well.  She tried on some pants with the hip padding and was uncomfortable about them making her hips look wide.  I was like oh god, here we go...
 
Also, I find it amusing that she wants black gear or gear with tough colors rather than the pink and purple stuff they market for women.

5'4"  114lbs  I imagine this is her first bike?            250  ???I'm sure you want to pick up her bike all the time when she drops it and kick start if for her everytime she needs it started . In my earlier reply I was throwing other options out there. If she can keep the 2-stroke in the power band this bike would be great for her. If not I would think a 4-stroker would be the way to go.  Now back to the 250 I agree with Alan on this for anyone that has been riding a while. I currently have a 125 and it gets me where I want to go in the sand. My riding buddies have a YZ400f and a WR426. So I am a little under powered wtih these bikes. I imagine a 250 would be perfect for me (my size) in the sand.
