I recently purchased a 69 450 scrambler I was wondering if the vin corresponds with it's build number,
my title shows the vin 450203 would that be the 203rd built? Just curious.

Quite possibly since the numbering began at 450001.

To be correct, your bike doesn't have a VIN . It has a frame number, which isn't quite the same thing . (And many US imports didn't even have that, only an engine number).

Was your bike the 203rd built? Possibly. It's certainly an early one - as all the American bikes are - as, according to Ian Falloon, a new frame number sequence of 460001 started in July 1969.
