I Am Looking For A Used 125 2 Stroke Just Wondering What People Think Is The Best Brand? I Really Want A 1998-up Cr 125 Because Of The Aluminum Frame But I Want The Brand With The Biggest Powerband Since I Won't Be Racing It All The Time. Thanks For Your Advice.

cr125 motors blow, everything is real strong but the motors are no good...

i had a 2000 kx 125 and it hit pretty well (no fear of hitting powerband)... and the motor was really good, sold it last year and it had the stock piston, gaskets, plug...

it was solid

ALL used 125's are maintenance headaches. Most get the snot beat out of them by fast guys, or negleted by dweebish kids. Either way, they're flogged after a few years.

You might consider a KDX200. Reasonable weight, quieter, and the motors last about twice as long. Just a thought.

the kdx200 also happens to be slow as a snail, I agree though it is very hard to find a good used 125

Looking to spend $1000 or under $1000 if possible to keep money for my other toys. The only reason I want a newer bike is that mine is a little outdated a 1978 rm 125 and I want a mono shock and something that has parts more readily available.

Your best bet is to find a top 5 "A" riders bike that races a 125 Still and has a mechanic that keeps the bike in top race condition...Why



1. the bikes suspension has been serviced and most likely revalved and works so much better than what comes stock.



2. the Motor most likely has HD Clutch componants, Quality Pistons and topends, Porting, head work & a dialed in carb and aftermarket exhaust system.

3. extra air filters and parts usually come with the bike at no charge



125 2-strokes do not make good used bikes....But if I were to get one id go with a bike like I described above.



they can be had but not for what you want to spend......

Last year's model is "outdated" an RM-C model will be cool for years to come.



A $1000 125 will break you in repair parts. Grab some decent shocks, a 79-80 250/400 front end and school the wannabe's. Running top 5 in Open B on an 83 Husky CR500 was a hoot. Air cooled, drums, forks mounted rightside up, 4 speed, twin shocker.



The rider is more important than the ride. There was even some sword swallowing sphincter spelunker on here recently saying how slow a KDX200 is. Try to hang with a 300lb 40 year old on one in the MI woods, skippy. Bring whatever you want. Dare you;)

I do agree it is mostly the rider but the bike i want to buy is a steal of a deal. It is mechanic owned and here is just a short list of the new parts:



top/bottom end,

clutch

plastics,

fork seals,

graphics and he only wants $1000

i recently bought a 2003 CR125R for 1800 because i thought it was a steal. I drove about 4 hours to buy it seeing only pictures on the local MX district classifieds. the guy selling it ended up being about 14 years old when i met him in person. he rolled the bike out of the cover of darkness in the garage and let the sun shine on it. i looked it over, and it looked a little beat... but for 1800 what do you want. it started first kick, which i found reassuring. that kind of "at least the motor is good" feeling. so feeling a little obligated from driving so far, and really wanting a big bike again... i payed him for it.



Got it home and REALLY looked it over and i could plainly see what a cob job bike i had bought. it was a bike that was POUNDED on by a fast rider... probably passed hands several times, then ended up in the 14 year old goons hands who rode it as a glorified xr100. it has the biggest rear sprocket the kid could buy so he wouldn't have to work to get it in the powerband... or maybe so it wouldn't stall so easy its kinda hard to tell. there was hardware missing EVERYWHERE on the bike. like they lost all the bolts to one body panel so they borrowed from every other panel. the tires are balding worse than a 'nam veteran. the clutch perch and lever are a really cheap looking adjust on the fly style... clutch cable is starting to fray. throttle is some really goofy looking unit possible salvaged off a really old bike. maybe it was aftermarket in the 80's? the aftermarket seat cover is loose, faded, and has kind of like frayed parts in it. The beautiful perimeter frame has marks worn into it where the shroud plastics rubbed it. thats part of the reason i figure it was ridden HARD. the rear hub has been broken and welded. and the best part is that 2 weeks after owning the bike the "first kick" motor blew up about 10 miles away from home with nobody around to help. i know its dumb to ride alone, but nobody was available that particular night.



Now i have about 400 dollars in parts at cost (i'm a mechanic at a bike shop) on my steal of a bike, hours of labor (sometimes hard to get motivated to wrench on a bike after you do it all day), and its still a pretty beat bike... just fresh and beat. The time I have in pulling the motor, splitting the cases, cleaning, scraping gaskets, cleaning, bead blasting, cleaning, would easily be over 10 hours. The shop I work at gets 40 an hour labor. retail on my parts would have been closer to 600 or 650. So now you are adding 1000 onto an 1800 dollar bike if you dont have the ability to do the mechanical work. Cant afford a 3000 dollar bike? Probaly shouldn't be looking at a used 125. Look at buying a used bike like buying a new bike, and making payments. Money down (buying the bike) and periodic payments (replacing worn out junk parts).



Thought i would vent my frustration. At least I learned a valuable lesson on what to look for in a bike before i buy it. This will most likely be my last used bike ever.
