I was wondering if anyone knew if the exhaust from a KMX 125 will fit a KMX 200? Mine seems to have snapped due to rust at the swan neck. As far as im aware the only difference between the 125 and the 200 is that the piston and barrel are bigger. (top end wise) I have a 125 exhaust laying around and dont really want to have to pay 100+ for a complete system.

Many thanks.

I improved the top end of my last 200 by sending it to Stan Stephens , I think I had a stage 3 tune. I also changed the sprockets. Sorry I can not remember what too.

The pipes are different.

If you manage to fit the 125 pipe to your 200, you will loose the top-end power.

You need a KMX200 pipe to get full-power

the 'big one' exhaust systme will fit if not i think you can get adaptors for the manifold

The frame is the same size but the exhaust port will be bigger on the 200 barrel so i doubt its the same, i wouldnt think it would take alot of work with a grinder and a welder though to get if to fit if you have got one try it on there it cant hurt.
