the question may be pre production kt250 models (500 made) versus what the true prototypes were.

take some pictures and post them. You asked a good question.

confirms the shock screws and frame differences.

No slotted screws holding on the shocks...

The bottom triple tree of the pre-production models had the steering stop ground down.  Also note the two bolts holding the key switch.

More differences between the pre-mass production models and 00001-004??  Another air box shot, Horn mount has only one bolt, Swingarm has a bolt instead of a rubber plug in the oiler, and front brake arm.

Right hand shifter spline sticking out.  Airbox differences

I think the preproduction prototypes were 350s.  What I am calling prototypes are the early hand produced machines that were sold in the States.  Some sample differences are below. The K instead of Kawi spelled out in the side covers, right hand shift spline in the clutch cover.

Would love to document the KT250 prototype differences (frame numbers KT2-00001 to KT2-00499) to the production KT250 pieces, any interest here?
