It should not be wrong, with a small displacement, single cylinder ... enlarge the difference in speeds makes very wise behavior (for industry that restrict, it depollue ...).
For us a sporty staging is dynamic behavior, even everyday on the road  ;)

I will come back with the SP staging, I must have the references of the gears that differ from the 4DL  O:-)

4DL2 is TZR-SP
3NC is DTR-TDR origine  ;)
4JT is tz125
1C3 is yz 125 +2003

There are plenty of elements to cross, a gearbox of a utility road bike is the worst of the worst case ... ::)
You will notice that the YZ is quite similar to the TZ with the exception of the primary gear ratio ... I let you interpret this fact where one pulls short and the other long, while neither is overdrive  ;)

Do all the TZR125 gears fit in all models?

4DL1, 4DL2, 4FL, 5AE,4FU have similar cases and similar gearbox
3BN (DTR and TDR) have trees, pinions, bell clutch similar to TZR and so must exchange

2RH is similar to the DTR and also to the TZR of this top (I have to compare the bearings to be 100% certain) ;)

I prefer working from a transmission 4DL by its staging and excellent finish

Back on the days they introduced them as "F1 mirrors"....  ;D But they are tiny and do their job, you can get them e.g. here..
