Old Kdx guy here, but new to the airheads. I have a pretty nice twin shock, air cooled kdx that was sold to me as a 1979 kdx 250. It has kdx 250 stickers, but it must be either a 175 or 400, right? Or what don't I know? Maybe it has a Kx 250 engine in a 79 frame? 250 mx top end on a 175? Are there numbers on frame and engine to verify size and year? It also has an obviously user modded exhaust which exists on the right as normal, with a factory pipe, then crosses over to the left with an old but nice answer silencer. Why would someone do all that? Any performance reason, or just a bored previous owner? They did a good job on the exhaust, but this whole bike baffles me. No pun intended

1979 KDX400, 1980 KDX250 and 1980 KDX400 were twin shock.

Maybe someone used a KLX250 frame??

Post an engine number and VIN / engine number. (head tube of the frame / front steering tube)

Here is an image of a 1980 KDX250 - crossover pipe.

Heck yeah. Great post.

I think I know what I got wrong. I have a parts bike, sold to me as a 1980 kdx 250. Different sellers. Parts bike is a unitrak with the exhaust on the right. I took all my info on blind faith. I bet the 79 is actually an 1980, and the 1980 is newer. Thanks all.

1980 was the first year for the KDX250. 1979 was just the KDX400. 1980 was KDX80, KDX175, KDX250 and KDX400.
