80, 100, of 125???

[Drtbke1210]

hi i'm 5'2" and 95 lbs. i will be doin track racing (but probably not motocross for a while) and some trail riding. If i were to get a 125, i would probably have to lower the suspension. i have long legs so i can it on about a 34" seat(I sat on a crf230f). my budjet is about $2000-3750ish. I have never ridden a dirt bike but i think i will be going with a friends family that has an xr50, klx 50, kx65, klx110, and a cr85 expert. i can start from the top. i am worried about gettin bored with an 80/85. I'm also kinds scared of a 125 since i'm only 95 lbs. i would have to control my throttle.

thanks

At 5'2 and a complete newbie on a bike I think a 125 mx'er would be a mistake. If your planning on track riding mainly then a KX/RM100 would be a good compromise.

I would get the KX/RM100 if i were you, its directly between an 80 and a 125 and can kick serious butt on the track or trail. The only thing better than a KX/RM is a KTM 105 SX. The best larger displacement mini, imo, would definitly be the new KTM 105 SX. Those are supposed to do some serious damage to the competition! The new SX is definitly worth taking a good hard look at. They are both roughly $3500 otd i think. That would leave you money for gear.

I had forgotten that KTM came out with a Supermini this year. The KTM is another very solid recommendation for you.

Even if i just wish that i owned one, i am a self acclaimed Orange Advocate. ; P
KTMs Rule!

 

[Drtbke1210]

how much are KTM's compared to kawasaki and rm100's???
thx

 

[Drtbke1210]

at my local dealer, the out the door price on a ktm105 is about $4,500
theyre so expensive ecause they're rare. the 125's are cheaper on cycle trader. lol
should i look used???

I would stay away from the KTM 105 since it is such a new model until they can prove themselves in reliability. I have seen a handful pushed back to the pits in the middle of a race. The KX/RM 100 has been around for a while now and is a proven solid bike. At your height and weight and experience, I think a KX/RM 100 would be great! Plus if you want to save some cash, you can probably fine a used KX 100 (like a 98-02) for less than $2,000.

Try to get a ride on a 100 and maybe a lowered 125, see which one has the most usable power the you can handle, and even if it isnt orange im sure you'll be happy with what you decide. :)

 

[kx134]

a older cr 125 is pretty tame, and if you are like most 95 pound kids, you are probably up to 110 by the time you read this. 85 no way. 100 great, but you'll wind up selling it. If you have 2000-3750 you want something that will last. It's true that a 125 is a lotta bike for a light kid, but if you want something to keep for a few years, the 100 will probably be too small.

 

[pyrofreak]

I guess i wasnt really thinkin about the whole growth sprut/puberty thing, lol. It will depend on exactly how much your gonna be growing and how long you want to keep the bike.

 

[Drtbke1210]

my dad is 6'4" and i'm starting to grow. i found a 2003 kx100 for $2200 with mx gear icluded. the bike is 3 hours away though and my parents don't wana drive there.

 

[kdxtodd]

you might as well buy a 125
