-
I have a RD 125 LC 30w egine is missing .
Like to now if its possible to fit the DTR 125 engine.I know the cilinder head connecties missing on the rd frame.
The 2 lower frame connecties are in the same place in the block?
TZR and DTR
Thans for your thouhgts

I would say that it may fit easy the DT125LC and the early TZR125 2RK engine. I remember a DT125LC fitted a TZR 2RK engine without mods. The DT125R engine type is not similar on the mountings.
@MadGyver Then its bether to find a TZR125 2RK engine .
Thans for the soulutions Mad

That's a shame.
Cannot you not find another RD 125 LC engine to go into it?

I'm assuming the DTLC and RDLC shared the same motor.

From what I've heard, the LC engine is more performant than the DTR engine.

The RD 125 LC yvps 1 gy have 27 pk .
The TZR 125 2 RK 2rk ,i can find the specs.
If the TZR 2rk have more ,is the best option smile -
RD and DT LC are the same block, but gear ratios differ. RD has a close ratio gearbox and DT has a wide ratio. Close ratio is not ideal if you want to go offroad IMO. Primary drive with clutch and 'middle shaft' length differs in the the LC engines I compared. Definitely get a LC YPVS engine if you go that route, -more usable power than without power valve. I have a DT LC YPVS close to stock, I reshaped the head and installed a Zeeltronic and put in 0,3mm carbon reed petals, the rest is stock. Goes well and has really good midrange torque for a 125.
I think the DTR and TZR engines are the same block too, but there is probably the same gear ratio difference, and possibly more
I have not tried dropping in a DTR engine in a LC frame (have only one DTR engine and many LC's), but have thought about it. Let us know if you try it!
