The tripmeter (little square block type as fitted on US models) you can still buy brand new in KM's. The original 78-84 tripmeter upgrades to the RMX250 tripmeter and is the same looking thing. I got one and the only difference from memory was that the RMX one had a more rubbery reset knob rather than hard plastic. Also i think its the same as the modern DRZ400? tripmeter in some markets too. I figured this all out ages by researching part numbers but i lost all the exact specific info from my computer. If you are good with siuzuki numbers and also have Zedder you might be able to work it out too, otherwise start looking at 90's model pre ADR??? RMX250 as they have the KM tripmeter.
If you still want the round speedometer then the 76 TS250 is the closest alternative. Only difference is black face rather than brown. There are guys out there that can reproduce the faces though because i bought repro faces for a CB750 from Holland and they are very good, properly printed (not stick on decal) with ND logos and look like they are originals. If there was enough of a demand i guess he could do them for Suzuki speedos too.
Here we go
original mile tripmeter is
Part # = 34721-41411
Part Description = _
Model Count = 7
PE175C 1978 172 PE175 DUAL PURPOSE
PE175N 1979 172 PE175 DUAL PURPOSE

PE250T 1980 246 PE250 DUAL PURPOSE
PE400T 1980 397 PE400 DUAL PURPOSE
then that goes to this in Miles so a lot of these models will have KM equivalents in other markets which is part number 34721-40600
Part # = 34721-40610
Part Description = TRIP METER
Model Count = 45
