should the ZS172FMM-6 be 6 speeds?

1-N-2-3-4-5-6? my final gear is only 5. i know this version of the 172fmm engine is rare but i keep seeing people saying it has 6 gears.

The original Templar X has the 172FMM-3A (5 speed) Listed in my sig below.
The 6 speed was released later in the same year:
172FMM-5 (counterbalanced 6 speed).

Can you take a photo of your engine stamp with "172FMM-6". Never seen this before.

The 5 speed engine is very common (but not in the Templar X), thousands and thousands of the -3A out there, and exceptionally reliable and easy to maintain. I sold my newer 6 speed Templar X. I like the kick starter and the absence of counterbalancing gear. To me, he counterbalancer just adds weight and a potential problem. And it is a dirt bike. I couldn't care less about a little vibration!!

The -3A is still available in the Templar M (Amazing $1600 bike today!).

What is the engine model number on yours? It is stamped behind the gear shift lever. If you have the 3A, consider yourself lucky!

I bought this engine in september of 2023 from an Alibaba seller i have bought other engines from. I also know 1 other person in arizona with the same motor he purchased around a year before. There are multiple videos in Russian about the motor on youtube. if you google zs172fmm-6 you will see it refered to as a 6 speed. it definitely is not 6 speed but i have only about 5 miles on the engine while trying to tune the carb. what is the recommended idle speed for these?

I have one of these in customs right now. Mine is going on a RPS COndor 150. Please update with experience, tuning, suggestions, etc. Thanks!

the 172fmm-6 is the 4 valve head, 5 speed non balanced engine.


if you wanted 6 gears then the engine designation is the 172fmm-5 counterbalanced 6 speed.


the dash number does not relate to the number of gears....

That 5 speed 4 valve engine looks GREAT. I wish I could justify ordering one to install in my Templar X. Awesome. The price is more than half of what I paid for my entire motorcycle!

Just as a data point, but my 2023 engine is stamped -3, but is in fact a 6 speed. I thought I read somewhere about some early ones being that way, but can't remember why or where I read it for that matter.

If the bike sits at idle of under 1000 rpm it probably has insufficient pressure for more than a minute. Exact number might be 1250 or higher. I don't mind a 1400rpm idle, but it is probably higher than needed.

Your question slipped through un-noticed, but I thought I would revive it.

If you only idle the bike for moments on the trail, 1200 rpm or even less should be OK. Sitting at a red light for a couple of minutes, maybe 1300rpm would be better.

I'd like to hear others comments on this.

Depends on the intake and exhaust. Is it a freeflow system, or the more restrictive stock system?

A free flow system can idle at lower speeds than a restrictive system.

I guess in some way (outside of the obvious ambient or engine temperatures), the oil thickness also plays a role, but I see no reason not to idle at 1k rpm, so long the idle is consistent (and not constantly oscillating between 800 to 1400 or so).
So long the bike doesn't stall...
