Help me choose: SX125 2015 or YZ125 06

The 4CS forks are horrible, which sucks because the engines are really good on those 15 and newer ktm/husky bikes. 
 

on a used bike, especially ones in your price range, I’d say it’s best to be prepared to drop at least $500 on parts shortly after you buy it. Whether it be on tires, sprockets, fork seals, oils and fluids, or whatever else, you’re more than likely going to need to spend some coin on something once you bring it home. I’d say it’s best to prepare yourself for that. 
 

based on your budget alone, I’d go with the YZ. An 06 is the same thing as a 2021 with the exception of the plastics. Buy it for $1,950, get the suspension serviced, throw some fresh tires on it, and go rip. 
 

Merry Christmas! 

Offer the dude with the YZ $1700 and be on your way to good times

I’m leaning towards the yz, I don’t like when I read, “just rebuilt” 0 hours. K why though lol. Ride to for a while, see if you like riding enough, sell that in a year for probably about what you paid, and go get a new or newer one 

I own a KTM 150, but with those I would get the YZ. The 06 YZ is basically the same as now and parts, plastics, etc readily available. The 2015 KTM is like 4 generations ago as far as looks of the KTM, the motor was updated in 2016, forks in 2017 to AER. If you go Austrian, buy the 2016 as it had the latest motor. Not sure where you are located, as not sure what SE stands for, but also take parts availability into account. Those are pretty decent prices based off US standards.

Personal opinion on that, often because the work is so cheap and simple on two strokes but you know people will ask anyway, so you do it so that:

A. You can sell it knowing it won't come back on you or stitch anyone up

B. Knowing you're selling a decent bike and can stick to what you want for it.

Most of us are buying and selling because we just want something new or different, not because it's needed. I agree bodgers and idiots, or straight up scammers or unscrupulous people, can muddy this up and make people rightly suspicious, but there are legit reasons. Like the above or folks building a bike for fun and then realising they just don't need it alongside their main bike or aren't gonna get back into riding as they planned, that's quite common it seems, etc, etc.

To the OP, I'd go with YZ I'd they can drop some money off it or the Husky.

I agree with Richy on the rebuilding part. Have an 04 RM125 I built last winter just for fun. Put WAY more money in it that I should have building it. I did ride it a couple times though, now just sits since I have a 150SX. I need to sell the RM this spring, but will be hard losing money on the deal.

I don’t know.  I’ve completely rebuilt top and bottom ends in some of my 2-strokes in the past, put a heat cycle or two in them and then sell.  It’s not always a red flag.  Sometimes you’re rebuilding it for your own peace of mind and then decide you want a change.

I only use oem parts, especially in the bottom end.

Now if they say fully rebuilt with hot rods kit, or some other cheap aftermarket parts, I tend to lean away towards those.

I’m gonna go YZ 

I did the same thing recently, rebuilt my YZ, put an hour of riding on it, and sold it since I wanted a 250F again. Just because it was recently rebuilt doesn’t mean there’s an issue with it.

Sometimes you buy a blown up bike cheap enough with the sole purpose of rebuilding it to sell on. Not uncommon for a fresh rebuild to have zero hours. Ask for copies of the receipt or pictures of the rebuild for proof.

Go with theYZ and make sure the shift stopper lever is updated

Those are all very cheap prices, not that I dont occasionally see running 125s around $2000 but those generally need lots of little things before they are track ready.  That said, its hard to go wrong with a YZ125.

I paid $3600 during the market increase for a clean 2006 YZ125, I'd jump all over that thing!

I’d go with the YZ as long as it was done with good parts and maybe knock a couple bucks off, if it doesn’t pan out get the newest Austrian bike you can find, the 16+ motors are really strong. Don’t be so scared of the 4cs, both of my bikes have them and I rode them for over two years, never knew they were “the worst fork” ever made until I read about them on Internet forums. Most people who complain about suspension probably don’t even know how to set sag so always take it with a grain of salt. 

Is it difficult to get Suzuki or Yamaha parts in Sweden?

What do you weigh? Rmz with ohlins would be tempting especially if you are heavier. 
 

The yz is known for having better roll on power than the ktm which can be helpful for a beginner and obviously the suspension is pretty good.

no used 250 4 strokes for me.  used 2 strokes are easy.

I don't have an opinion on the 4 strokes.  I can tell you that riding a 125 hones your skill and is a great place to start.

$1900 for a Yz125 in the U.S. is a steal.  I would grab that bike today.
