I'm 5'5 and I weigh 125 pounds and im 15 also could I race this bike in the 125cc class or the 250 4 stroke class in America in Michigan?
-
Yes.
The 125 & 150 are the same bike.
-
Yes but could I race them in those classes like could I get sponsored racing a KTM 150sx in those classes?
-
I'm sponsored and I race a 150 in the 250f C class
-
In America and can I do it in Michigan?
-
Yes I live in Texas I'm sure you can race it in michigan. Look bro I'll give you the best advice I can give as only a novice rider. I started riding a year and a half ago and knew that the best way to learn was a 125. When you're a beginner it really doesnt matter what size bike your on most of the time your lap times will be the same. You'll just be faster in certain places on a 250 but it would be way more dangerous. The 150 man It's the best bike i've ever ridden so fun, so much power, just an awesome bike but the power delivery on it certainly wouldnt be fun for a beginner in order to be fast on it you have to carry momentum, it basically rewards you all the things you learned on a 125. I went to the ktm oak hill ride day where Tommy Hahn blew up the 150 in one day, I asked his opinion of it and he said its the most fun he's ever had on a dirt bike and thats what a factory 125 feels like! But in all honesty just be patient man i've learned you cant rush motocross it takes time and there are numerous things you have to learn. There is no bike you can buy and just be ready for even the novice class. Learning and progressing is part of the fun just enjoy the ride!

most amature races are 200cc and under, 201cc to open. i believe up to B level

Thanks but everybody says the the yz 125s have no bottom end for trail riding because I'm going to be trail riding for a whole week at camping

Then don't ride the bike in the bottom end... And use the clutch...

I'm a biggner and not used to power

I don't think you are listening to what you are being told in here.
A 125 is probably too much bike for you.
If you insist on getting a 125 , be aware that none of them really have alot of bottom compared to a 250
When a 125 gets revving, it produces A LOT of power.
To create more bottom end in a 125 you need to lengthen the intake tract between the reed block and cylinder.
Moose racing makes an aluminum spacer called a "TORQUE SPACER" for almost every 2 stroke ever made.
They cost $30
This mod alone will give you great bottom end for cheap
Your other option is to lengthen the exhaust tract after the port
FMF makes a pipe called the "GNARLY"
It produces a ton of torque and is made out of 18 ga steel so it's tough
It costs $200
It will work with the stock silencer
HOWEVER
If you are going to be trail riding you should also equip your 125 with a spark arrestor
FMF makes 2 great models that do not rob power
Turbinecore 2 ($120)
"Q" ($150)
The "Q" is a little more expensive but it is quieter than the Turbinecore, which is a good thing.
Loud bikes, although assumed to be faster, are not as fast as people think.
They only seem faster because the rider is subconcsiously scared by the loud sound.
It is a natural reaction that you have no control over and has been scientifically proven.
The loud sound also pisses off nearby people that do not share your love of dirtbiking.
The combination of of these items {torque spacer+Gnarly pipe/SA) and the addition of an 11 or 13oz flywheel weight
($110 from stealthy)
will give you a ton of bottom end and will smooth out the power delivery throughout the entire throttle range.
GOT IT????

ok i'll be that guy. i read your other thread and from the sound of it you have zero riding experience. if you go hop on a 125cc motocross machine 1 of 2 thing are going to happen. 1. you wont even get it going and your going to stall it out and flood it then fowl a plug etc... or 2. your gong to loop it so hard on your a-- you wont know what hit you. eventually you will figure it out but you will be chugging that 125 around fowling plugs left and right and to be honest you will learn zero and have about as much fun as kicking rocks.
you need to learn how to ride. most on here have got agree with me even though we are all pro 2t but go spend 5-700 or even less if you can find one and buy an old xr100 and go ride the snot out of it. then when you have comfort, control and a little seat time under i would tell you if your heart falls to the 2t side sell the little xr and go find a big wheel cr 85. you said it yourself, your 5'5" and 125 lbs. your smaller than my wife and she has followed these steps of progression and now i can happily say she is a decent rider.
just my 2 cents but hey i have dont know much after 20+ years of riding and racing motocross and teaching many numerous kids and adults the fun of riding. i would hate for you to ruin what is the greatest sport buy forcing yourself into or onto the wrong machine.

this is what it should sound like when you ride a 125. enough said.

The '67 Kawasaki 120 is also a great beginner bike, if you can find one (in other words, find another bike).
But seriously, the bike you're looking for depends on what you want to do with it. If you're out to go straight for zero-to-racing, I'd say just don't - start with trail riding or something just to get the hang of using a dirt bike. The thing with trail riding is that you can get away with using a machine that's WAY beyond your skill level to race, and not get in too much trouble unless you're an idiot (and by the way, a very significant percentage of the world is). When I was your age, I was on a 250 two-stroke, but then I was also much bigger than you. I recommend starting with an 85 or something. They're a bit like dogs in that they're not terrifically dangerous, until you really push your luck and back it into a corner, but until then can be your best friend. A 125 is more like a trained wolf, which can maul people to death on your command but may turn on an inexperienced master. A 250 is like a trained tiger, which is as deadly as anything you'll ever need, and can actually be surprisingly cuddly and playful (but god help the man who gets too casual). And then finally, there's a 500, which is sort of like having a Tyrannosaurus as a pet, capable of killing everything in its sleep, including you.

very nice analogy jetz ;D

As Westside said, Learn to ride first.
The worst thing you can do is buy a bike that scares the shit out of you so you stop riding altogether. :(
Buy an old XR or similar, thrash the shit out of it, THEN buy a 125.
A friend of mine started riding just 5 years ago at the age of 35.
Never been on a bike before in his life.
Got him a XR200 to learn on.
After a while he got faster and faster until the poor little bike was having it's neck rung everwhere.
Now hes on a KDX and loves riding. :)
-
What these guys are saying is true. Definitely don't get a 150. Too much extra money for 25 extra cc's that will pop you on your butt. If I were in your place here is what I would do
1. Attend a weekend MX school where they allow you to rent an crf100 or another small bike and listen to everything they say. Get use to the power delivery and learn what a power band is. Since you will be getting a two stroke, ask if they have a two stroke you can ride. Take it nice and easy.
2. Go out and buy an 03 Yz125. Best 125 motor you can get for bottom end. Also, it is a five speed.
3. Buy an FMF pipe and preferably a TurbineCoreII silencer (best pipe for bottom end imho) or the Q which is quieter.
4. Get some friends with riding experience to help you adjust to your 125.
And to answer your other questions you can race a 125, 150, and a 250 two stroke in the 250 class on an amateur level in most states.
-
Oh.. and I can say that the XR is the best option. I started out on the 200, and rode the wheels off of it. Actually, I rode it so much that it just wouldn't start anymore(my fault actually but that is another story). It took several years on a slow, heavy bike in order for me to safely hop on a 125.
-
I read this young fellows post, and didn't see him write anything about not having ridden before.** I Did see his comment about being a beginner, so it could be the absolute case - but it could also be the class he rides in?**. Perhaps it's the typical question about becoming sponsored that new riders often come out with that has lead some to think he's an 'absolute' beginner.
If he already knows how to ride, and takes some of the advice given by some here, I see no problem with a 150. It, to me, would be easier to ride than a 125. I noted him saying he's not used to the power, but we've all gone through the stages of moving up with bikes, and most of us have survived.
As it is, I see a lot of put downs (but amongst them , some very good advice) of him.
It seems to be a really good way to drive the young bloke to riding a 250F, what with how easy they are to ride........
Apologies to people if I've been a doofus and missed him as being a completely new rider, but if he's not, piling on him isn't going to help keep a young bloke on 2ts. Which is something most of us would like to see - more 2ts being sold and ridden.
*PS,
I just saw his other thread - I think he's got a valid comment about being scared a bit by a 74 CR125 chassis'd 185 as having the potential to scare him. I doubt that it would be a very shmick example of a conversion, and if most people here jumped onto a 74 CR125 chassis' bike, they'd give themselves a fright. I raced CRs etc in that era, so , whilst they were good things then, I have no rose coloured glasses about old MXers compared to now, even though I have quite a few. :D
-
yeah bearorso, this is the third thread he has posted on the same topic. I imagine that someone told him about Sponsorhouse.com, and he has gotten one or two sponsors from there, highly doubtful that he has a fullride with the experience he has claimed.
Chris I want you to know that with your limited experience, jumping into racing is a bad idea. I have personally seen the effects of what happens when people think that MX is as easy as it looks. Parents that by thier 13 yo a 85 for a first bike and take him straight to the track after a couple of weekends of riding in the yard or nieghborhood sand lot. They've seen these Pros on TV or at the local track flying over doubles and 80 foot tabletops, and think that because they successfully managed not to loop out in the first couple of weeks learning to ride, that they are ready to go hit that 80 foot tabletop.
this usually results in an ambulance ride, and sometimes they get a lift from the coroner.
Seriously man
Get the RM85L, KX85L,( Both of those are the bigwheel models) KX100, KLX140, XR200,CRF150 (not the r), DR200, DRZ125l, TTR125L, something that you won't get yourself into trouble on and get some saddle time before going to the track. trail riding is the best way to become a better rider add to that a motorcycle school, and you'll be on your way to racing MX in a year or two. Don't listen to your buddies that are already on a 125 or 250f that have been riding for several years, and trying to make you feel like a dork for getting a play bike or a smaller/older model than thiers, dirtbiking is not about who has the newest coolest ride/gear, it is about FUN.
It is about being in control, and believe me riding a bike that you cannot control is no fun.

jetz,
I gotta say that post scared the crap outta me. :o
trannasuarus what?
-
As it is, I see a lot of put downs (but amongst them , some very good advice) of him.
I don't see any put downs at all. From the sound of it he has had very little experence on a bike. If an old XR185 motor scared him I don't think a 125 would be the way to go for him.
Of course only he can answer that question.
Better he start of on something easy and then progress then give up altogether because he scared himself shitless.
He could be the next RC though, We don't know. ;D

True, but he has 2-3 threads over the same subject, and on every single one everyone is telling him the same thing.

Find a mid 90's CR80. The 85's seem to have a little too much kick, but the 80 Hondas seem to be a little smoother power band. Great beginner bike in my opinion.
-
Who knows maybe the kid is born with riding ability. My 1st mx bike was a 125 and was wideopen on day 1. A 85 cc would be big enough, but I suggest getting a 125. Try to find a cr125 05 to 07, the cr125 has the best handling and there very durable. I put a rad valve on my 06 cr125, it helped the low to mid range power alot, it comes off corners a gear higher and lifting the front wheel, good stuff.
-
Oh yeah he's a modern day Bob Hannah.
-
Am I the only one who thinks cr 125's are dogs. They're sooo slow i've ridden one with the whole boyesen set up pc exhaust all the goodies and the yz and ktm just felt like it had way more punch.
-
??? My friends dad was keeping up with 450's on his 04, even passing them on the track... :-X

Not the 05-07's
-
the one i rode was an 02 so maybe that yr the motor sucked or somethin
-
it's not always the motor that get you there first.
it's momentum, line choice, and preparation, that win races
-
I know I was just comparing the honda to every 125 i've ridden here's my breakdown none of the bikes were stock as far as pipes and reed cages. I'm a top 5 C rider in the local stuff so not super fast but I can deff ride.
02 Honda CR 125: I actually probably had the fastest lap times on it cause it was easier to keep it pinned everywhere but it felt slow
05 Yamaha YZ 125: Had a great motor it felt pretty good everywhere, I really didnt like the handling very much.
Kawasaki KX 125: I've never ridden one
01 Suzuki RM 125: Great handling, good suspension, the motor was only good in one spot up top.
06 KTM 125 SX: Very strong motor but not as rideable as the others I'd say the power came on hard and it wouldnt be a good bike for beginners
I'll just put this one on there for fun and if any1 wanted to know
09 KTM 150 SX: Awesome brakes, pretty good suspension, the motor honestly feels like a 125 on steroids it pulls so hard, but its all mid and up top, once you ride with the hydrualic clutch I'll never go back to anything else.
-
Yeah the 02 cr125 didn,t have a strong motor. My 04 cr125 stock was slow too, motor work is needed the transfer ports are too high. So you deck the cylinder-lowering it, port,head mod, borre carb to 40mm,icat, pc pipe,silencer,v force reed on it, I want to try a rad valve on it if I keep it,since the rad valve worked great on the 06 cr125. The 04 cr125 modded makes 37-38 hp and has a super long mid range, the 04 now is stroked and borred 22 foot lbs of torque, 40 plus hp. I,m prob. going to sell the 04 cr125 or the 06 cr125, have to make my mind up. I think a mod bike is a tough one to sell, what do you guys think. thx

All I have to say on this subject is that it is waaaaay more fun to ride the crap out of an under-powered bike than to be scared shitless on a bike you can't handle. A 250 two stoke motocrosser has more power than 90% of the dirt bike riding population will ever use to it's fullest potential. I'm 5' 10" 190 lbs and am 5-6 seconds a lap faster around an average track on a 125 than a 250. Dirt bikes are power-on handlers - they go faster through corners, whoops, jumps, etc if you can keep the throttle pegged. How many of us can realistically do than on a 45 hp 250?? If you are really a beginner, buy something like a KLX110, or even an old suzuki DS80, learn throttle control, braking, weighting the outside peg in corners, wheelying (including nose wheelies), then think about a race bike. 2 stroke or 4 stroke, you will either hurt yourself or break your budget learning on a race bike. Just my 2 cents. ~ Russ

X2. The 150 is the perfect bike.

you are about the same size as my wife and she is a complete novice and her first bike is an 05 rm 125. the first day riding she fouled a plug so i told her to ride in 1st gear only. she wasnt going fast but on the straights she cleaned it out enough that she hasnt fouled a plug since.
Now she has gotten used to it and can keep the revs up and she hasnt crashed it once due to the power, i just made sure that from day 1 she knew that if she twisted that throttle too hard it would spit her off before she knew what was going on. as she got more confident and used to the bike she can ride it harder.
if you want a 125 or 150 go for it but treat them with respect cos they will kick your ass if you dont
