Shoudn't ever need to rebuild them really.  As long as the fueling is not messed with or increased along side any de-restriction (not running lean) there shouldn't be any piston problems, and apart from that, there's nothing else in a stroker.

Great little bikes, my old 125 KMX was more than capable of 85.

Crossers do tend to be a little more "needy" than a traily would be but a lot depends on how you ride it - use decent 2 stroke oil, don't thrash nuts off it and it should be fairly reliable.  Generally a bigger CC will have been thrashed less.

I had a KMX 125 too when I was 17 - we took the airbox lid off and the neck out of the front pipe and it went awesome - better than my CR at the time (and then went bang) - as DX said - if derestricting then watch out for running lean and melting the piston  :shock:

KMX 125 and the RM 125, pretty much the most stolen bikes of all time  :lol:

One wire and your away...

That's something to bare in mind though. Scally [!Expletive Deleted!] will just pick em up and throw them in to the back of a van, so disk locks aren't worth it. Chain em down every time.

thanks guys
I know more than well that if they want something it will go but it will be in a shed, its just for a weekend thing thats why i dont plan to spend a great deal on it.
I only asked becase evrytime I see an add for a half decent little 2 smoker it always says its just been rebuilt so I was wondering if it would be just as well to get a 4 stroke

What is a rebuild in a stroker?  Other than a big end bearing take the head off and replace the piston / rings / gudgeon pin / small end (which all comes in a £30 piston kit) there is nothing else.

If an engine has just been rebuilt (see above ;) ) I'd guess that it's been de-restricted and has the incorrect jet fitted. a couple of seconds of WOT and the piston will melt.  To fit a new piston in a KMX esc crosser there access is OK, it's about 30 minutes.


Just dont ask me how I know  :roll:

I'd say it would depend on what you are using the bike for. If your a top class rider who is a the sharp end of expert racing then yes you will need a fair amount of maintanance, top end rebuild every 10 hours at a cost of at least £75.

If you just want to goon around a field for a couple of hours every weekend then it should be ok, just don't forget to use a reasonable 2 stroke oil and clean the air filter every time you go out.
