I have a DT1 S . Gears (have not had mine open to see what differences - possibly finer or coarser teeth ) and ratios appear to be the main difference (ratios are I think the same as later DT1 's. ) . From what I have seen with the bikes delivered in Aust. possibly some had a small tacho and others did not. A 21" front wheel was a "GYT" option as well as some other engine tuning items. Fewer "S" bikes produced than any other early DT1. That probably sums up the main differences.

Also I think the "S" tins were gold with a black pinstripe?

Could be right on the colour as that is what my 2 are with a black oil tank and silver head light ears...… Bit hard to find pics. of an original DT1 S although mine is still in original paint and colours.(one of mine is missing head ,carby , cylinder, exhaust etc. )

I have a US market parts book for a DT1 S .
It shows the Fuel tank and Oil tank as the same part numbers as DT1 B .
That's Candy Orange ( Gold ) tinware , but also a Pearl White option too .
That may not apply to KJB's Australian bike .
