Decided to go for Galfer to match OEM, and liked the look of the slotted wave design the same as the Factory TM bikes use...
Appreciate the follow and comments, loving the bike!

Graphics look great - really clean look!
Where do you find parts? Sweet build!
TM did it right and instead of just using an over-bored 125 they built a completely different engine with a different crank, stroke, cylinder etc.
These pics came out amazing!
Would you say it's worth/possible upgrading an '05 YZ125 to operate on a somewhat equal level?
Debating whether to modernize the YZ that I already have or spend the 9.5k USD a TM costs here.
For the record I'd go for the 144.

Do you know if there are any major differences between the 2017 and 2019?

Anyways since most people here are from north america and are not so familiar with the TM's I'll try to chime in with some info. I live in Europe and here these things are still rare but more known than on your side of the pond. If you want to know the difference between any version of TM from the aluminium framed ones (from 2008 on), just go to the TM website and go to the download section. There you can find parts catalogues for every bike, frame and engine separate. Is there no catalogue, then go to the first catalogue from the year before and so on. Even then you'll see that when you compare parts numbers not a lot changes each year, it's more of a evolution each year. 4t is 4 stroke, 2t is 2 stroke. Frames are unchanged since 2008 except for 2019 because the 250/300 has the oil now in the frame. Still the same frame but now with sight glass and some other small changes. Engine cases cannot be found on the catalogues because of case numbers which need to match, so it's difficult to check changes there but with some google search you'll come a long way 🙂. In your case it seems not a lot has changed. The bikes from 2015 on are the same until 2019. This year the 250/300 frame is different like said earlier. Also at 2016 they change the type of aluminum used for the frame, only difference than this between 2015-18 and 2019 is some fork internals, which you can easily order online for cheap and the stickers + exhaust. Engine wise there are more differences. From 17/18 to 19 they changed crankcases, piston and rings. All the rest is the same. From 16 to 17/18 they changed some gearbox internals, and some clutch plates. 15-16 had changes in gearbox shafts. All in all it's easy to find usg the manuals and a little bit of common sense. TM clearly states which parts are different from the year before. I Hope I helped you a little bit and if you have any questions please DM me because I don't know if BD wants his thread filled with things not really related to his build. If he's okay with it just post and I'll try to help.

I just did a ton of testing a few weeks ago at Varner Motorsports. We tested pipes, silencers, cylinder heads, fuel, jetting, cylinder porting, timing, ignitions, you name it. After 60 dyno runs (mostly on the 144) we picked up over 4 HP on both bikes.
The best combo on both the 144 was the stock pipe and PC silencer. On the 144 the HGS pipe that comes stock was clearly superior to the PC on the stock and modified cylinder. The stock pipe makes over 3/4 HP more and extends the power- band another 800 RPM.
This pic below is the PC pipe/PC silencer (red) vs the HGS pipe/PC silencer (blue)
The 250 dyno chart below shows a ported/tuned 2005 CR 250 vs a ported/tuned 2018 TM 250.
The bottom to mid is better on the high compression CR but the TM makes over 4 HP more on a very modest fuel (70% pump gas mixed with 30% Sunoco Supreme Leaded)
Looking forward to a ride report..
