What's the main differences between an offroad bike, like my TTR-125 and
MXer like a YZ-80? I know the engines are 4 and 2 strokes respectively, but
what are the main differences in the frame, suspension and other components?

TTR 125 is for trail riding, YZ80 is full-blown race bike....

TTR maybe 12-16hp, YZ80 around 24-26hp (CRANK people!)

TTR weighs about 25lb more than YZ80

TTR has drum brakes rear, YZ is all disc

TTR has maybe 6-7" suspension travel, YZ80 around 11"

In a 5 lap MX race the YZ80 would most likely lap you twice on a TTR-125...

'A' grade YZ80's do the 90' table top at our track no problem, it would be
suicide to try on a TTR 125!

the ttr has a doughy 4s trail / play riding engine, the yz has a snappy,
peaky 2s that can compete effectively on an mx track. Same goes for
everything else basically, ttr for fun trail riding, yz for fast
racing. the ttr will be very easy to ride, the yz won't. I hope you
only wanted something as general as that...

Wheelies - and the ability to get your friends to loop the thing when
you tell them it is only an 80...it's a TOTALLY different bag...the YZ
has about a 400rpm wide powerband. You have to be on your game to ride a
2-stroke 80...and like to do clutch work.

Is this a quality response for Sir Bob?

I'll admit. You are right. However, they share a lot of similarities. For
a complete set of specs go here (hey it is a manufacturers website so I know
Bob will support the information)
http://www.yamaha-motor.com/01motorsports/01mcy/offroadbody.html


> TTR maybe 12-16hp, YZ80 around 24-26hp (CRANK people!)


Which website gave you that? I'm surprised they'd advertise that their own
bike varies as much of 2 hp depending on which TTR125 you buy.


> TTR has drum brakes rear, YZ is all disc


Actually, only the TTR125L version has the front disc. The regular TTR125
has drum both front and rear.


> In a 5 lap MX race the YZ80 would most likely lap you twice on a
TTR-125...


Bzzzzt... wrong. All depends on the rider. I have personally witnessed a
pro rider on a TTR125 L blow by a B rider on a CR250 down a back hill sandy
straight.

It would be suicide to try it on any bike if you aren't an A grade rider.

I thought you only provided useful posts Bob. Hmmm, this wasn't too helpful

I bought a y2k cr80 for my wife. It's a bit much for her, it will loop out
if you don't know what you are doing. I wish I would have bought her a 4
stroke. I saw a young person riding a ttr125 at the track a while back, it
looked like a well mannered bike. I guess it all depends on where you ride
and how experienced your wife is.

Well, seing as I have a YZF250 that wouldn't cut it. She does the laundry
so I can't justify giving that up for an XR.

Now, if it was a CR and riding gear I'd consider it :)

What about if we crash her through a fence and tear the front end off
her? Do we have to pay to rebuild it, or is it "you crash it, you buy

My wife has been riding my old kawasaki KE 100, and can't keep up to me on my
yamaha IT 175K (old enduro bike), especially in deep sand and steep hills.
I'd like to see her on an enduro bike but she's only 5'3" tall and not too
strong, so bikes like the WR 250 and KDX 220 are out of the question. She sat
on a TTR-125 and likes it, but I sort of get the feeling that its not a big
enough step to be worth the money, and she would still be lagging behind even
intermediate riders like myself. There are a couple of barely used kx 80's and
a kx 100 for sale in my area, and I wonder if one of those would be a more
appropriate bike for her. She's never going to race nor does she want to do
massive jumps, but she would like to be able to keep up to the pack when we are
out trail riding. Are kx's too race oriented to have fun on the trails? Am I
underestimating the ttr? It just seems like the kx has more power, more
suspension, less weight, better brakes, and a similar seat height.

Maybe you could pick up the KX80 and get some cylinder work done for a few hundred
bucks to smooth out the power delivery. I've heard of companies boring/porting
KX60s to get a broader/smoother powerband for trailriding and/or less experienced
riders. I would start with the 80 vs. the 100 because there's probably more room
for modification.

As much as I dislike two strokes, the KX is probably a better deal. The
TT-R is under powered and under suspended. The KX100 has incredible power
for such a small bike. It's not as forgiving on the trail as the TT-R but
it has all you need when you need it. She'll be a better rider six months
after riding the KX than she would be after a year on the TT-R.

well, I am 5'2", female, and just graduated from a KX100 a couple of months
ago. I rode mostly in the woods with it. She could definately keep up on it,
that would not be a problem. You'd probaby want a different pipe/silencer
than the stock one though, since it doesn't have much low end. It's way
better than the 80 though, and the tire size being bigger sure helps in the
woods as well. I just had to really keep mine in the pipe, and blow it out
on the fire roads, since it doesn't put so well in the trees.
I only tried riding the TTR-125 once, and I was bored shitless...it seemed
really gutless to me after being on a 2 stroke.
The 100 will probably blow your IT away, that's what I had (75 IT175) before
I got the KX, and it was way too heavy for me.
The KX is light, managable, and lots of fun. The only thing you can't really
do with it is ride the dunes...it just doesn't have enough power...that's
why I went to a YZ125..since I"m a sand lover.
I also tried the KDX220, and although I could reach the ground, there's no
way I could pick it up if I dumped it...too heavy.
feel free to email me, or she can if you have any other questions!

My son has a 2001 KX 100. What a great bike. It handles well, the
suspension is plush but can still take the big hits, and the engine is
fantastic. It has all of the power you expect from a small bore 2 stroke,
but with the power valve, it actually runs great a half throttle and at
lower RPM's. Can't say enough good things about the bike. My son hads big
smiles on his face every time he rides it!! And that's what it's all about.

That sounds like a neat idea, but I'm leaning toward 100 for the larger wheel size.
It's good to know there is a potential remedy if the bike is too peaky for her.

I would be curious how she does on the KX 100.

Last Sunday I rode with two women, one on a TTR-125 one on a TTR-125L.
Both bikes made it up some steep climbs, but the TTR-125L with the larger
wheels with a front disk brake looked like it had more potential.

1991-2000 XR200's have fairly low seat height at 33.5 inches
vs 34.3 for the 2001 KX100. More weight, drum brakes and gas
that won't work in your IT175 are the main disadvantages.

I have a 1987 XR200 (and 1999 XR400). The XR200 is typical XR.
No big hit, but lots of torque out of the motor. Mine starts in
a few kicks cold. One kick hot.

Holley,

I am thinking about a TTR-125L for my brother/son. Neither has _any_
experience riding bikes. My brother rides snowmobiles and is into sno-X
with me - jumping my fiancée's snowmobile all over the place.

Would you consider the TTR-125 as a waste of money at this point? My son
sat on it and he said it felt "right", which says a lot since he sat on
about 15 bikes in the last couple of days - including the KX 100 which is
his second vote. I like the price (since I'm fronting the cash) and I like
the fact that I won't be doing a top end every month being a 4-stroker. I
also like the 'mild manners' of this bike. I have no interest in my ex-wife
freaking out because my son got hurt while riding with me.

If my brother and son improve to the point where the bike is too lame/small,
I won't feel bad about sizing up to a 2T 125 like a KX, but I don't want
that kind of power to start and I would be pissed if the extra $1500CDN for
the KX 100 was thrown away because neither likes (read: are brave enough) to
ride it...

What was your riding history before jumping up to the KX 100?

Three months in he'll either be beating it to a pulp or you'll be spending
$$ out the wazoo to make the bike keep up with his increasing abilities.

Put a rev pipe on it to flatten out the powerband.

> What was your riding history before jumping up to the KX 100?

My son started out on an XL-80. Took him two trips out to start beating the
crap out of it. The KX-100 was a dramatically different bike but it earned
his respect. I put an FMF rev pipe on it and it make a tremendous
difference in control of the power. I can get a year out of a top end on
his bike. He does a few enduros each year with play rides sprinkled in the
rest of the time. The only thing it's lacking is a kick stand.

Thanks again to everyone who provided advice/insight on the ttr 125 vs. kx100
thread. I am now the proud owner of a 1999 kawasaki kx 100. We're taking it
out tonight so my wife can start getting used to the motocross powerband. It's
the same color as her last powerband (the ke100 was green as well), so hopefully
the adjustment is not doo difficult.

how much did you pay for that band stretcher?

why not get it between two screwdrivers and turn one screwdriver one way and
the other one in the opposite direction that would stretch it? - or and the
newer bands too thick to stretch without machinery ?

Get a flywheel weight for her. The Steahly is quick to install and
uninstall. It will make the bike's power delivery very controllable,
without sacrificing any of the real power. All you will lose is the
jumpiness in the delivery.

We took the new kx 100 out a couple times this weekend. The powerband is fine; in
her words, "It's a little scary, but I can handle it." One problem she has though is
the bike stalls very easily. Not so much on acceleration, but when she is stopping
the bike or sometimes just idling. Would a flywheel weight help for this?

More than anything else that you can do, except maybe not let off the

My wife's KX100 and many of our friend's KX100 do this exact same
thing. You can fix it by upping the idle a little or adjusting the
clutch. Once I replaced my wife's clutch plates and springs here
problem went away totally. A good side note for you is that adding a
torque pipe and torque reeds does not make the bike have better low
end, but it does give it way more power. My wife's first gear really
sucks now but second through sixth kick ass. Later Andrew

I think my CR's powervalve was faulty <seriously I do> so maybe it took out
the bottom end powerband? - hope those bottom end ones ain't expensive -
wait a min . . . what do I care I don't even own the thing anymore!
