"Above average"

What things have gone wrong with the motorcycle?

The one thing so far that I didn't like was the oil drain plug on the right side. Too easy to strip out by over tightening. My fault.

Guess I could say I don't like the bolts that stop the triple tree from hitting the frame. I have bent many of these. Where the bolt screws in is getting bad... but still works!! Crushed the e-box by the neck also.. but still works!!

Worries me about the chain being so close to the hydro clutch too. But once again, no problems.

General comments?

Very happy with the bike. Very nimble, and light to handle. Quick enough, and makes a nice trail bike with the right sprocket.

One of the best web sites for support groups out there. Any questions are answered. This is a big help and makes the bike worth more... to me.

What would be better for woods riding and racing, the KTM 250sxf or the KTM 125sx?

I own a 2003 125 SX and it is an absolute weapon off-road.. it has immense acceleration (quicker than my friends 250 SX-F) and is so much lighter and flickable through trails it makes his SX-F boring (literally).

As long as you jet it right, it will not foul plugs, and has awesome low end power and will chug along like a tractor all day. The performance for a 125 is breath taking, and the sound it makes echoing thru the woods is awesome!

Look at most of the top professional off-road riders, they prefer the two-stroke... the smile it will put on your face is worth it alone.. they are the cheaper and better choice.. 125 SX all the way!!! You won't be disappointed, GUARANTEED

What is the oil to fuel ratio on a 2003 125sx?

Thanks.
