DT125R FORUM

@HOTSHOT-III Thank you lad. I saw a video on yt about the tz style plastic but the link didnt work and google gave me nothing. Also i ride it as a hobby and mostly smaller tracks bc the bike struggles on bigger tracks, i live in Estonia. And about the suspention i was thinking on the rear shock you gave, but the front. I was thinking on putting heavier oil like w20 and spacers on the springs. As i said my budget isnt that big and most of it is going in to the restoration so i am going to be left with probably 300 to 200 euro for straight upgrades and new parts. I am gonna respond to this in more detail after Christmas. Right now im typing this on my phone and im a bit of a hurry with the Holliday activities.

Hello.

I am gonna restore/rebuild my dtr 125 1997 and i made this thread to post what I'm doing and to ask for advice.

My plan of action is to:

1. Take everything apart
2. Remove rust and paint it with new colors.
3. Restore the plastics.
4. Fix my extremely soft suspension.
5. Fix/look over all the wiring
6. New parts

I was thinking on painting the frame with the metallic Subaru blue, does anyone know if it will look nice? Also I'm gonna paint over the plastics and try to put a Honda crf 250 2017 rear plastic tip on it, I don't like like the original rear plastic i think it looks like a egg. If anyone knows if there is a yz like rear plastic that fits without modification please tell me.
I'm gonna start the restoration some days after Christmas and then I'm gonna start posting pictures. Any advice or stuff to look out for before the build is greatly appreciated. Also my budget isn't huge so i cant spend a lot on new parts or stuff like that. The main thing i want to do is give it a new look and make it look like a roadworthy motorcycle, right now it looks like a barn find that was kept somewhat nicely. Excuse my english its my 3rd language.

Hello again.

Ive returned and i will start my build waay to late in to the summer.
Ive ordered new parts and id like to know yalls opinions
The parts:
Full Athena exhaust,
piston,
turn signals,
Plastics,
Pwk 36 carburetor,
Athena gaskets,
Bearings and bushings,
And a little paint.

Im planning to go full black on the plastics and put dark blue decals on them, also im going to paint the frame yamaha 403 dark blue.

Ive already upgraded my front suspention with dt 125 1980-1990 sumting motocross springs, heavier oil 15w, and put the stock spacer in my right fork. For the rear ive maxed out the shock and it rides lika dream even without the new parts yet.

The engine is in pretty good condition, all the gears are good but ive noticed that some bearings need to be replaced. I am very suprised that my crank is still good and not rattling beacuse ive used the bike for enduro/motocross/road usage. But my 3mb00 cylinder has a mirror finish and with my old piston has 75 psi but it still ripps and keeps up with a 2017 ktm sx 125 on full gas. Im sending the cylinder to my local shop to get it honed, then il run it with my old puston till the new parts arrive.

On the electrical side, everything is in meh condition. I need to rewire some parts and make some adjustments so i can put on my new turn signals. The biggest problem tha i have is that my derestrictor switch dosent work on the first try, i need to switch it for 30 seconds or so that it derestricts it and i have been thinking of putting somekind of a toggelable repeater on it so i dont have to mess with it, but i havent decided.

About the frame. It has some rust and dabage but mostly its all good, as a said before im thinking of spraying it with yamaha 403 dark blue paint, other than that im going to replace my swingarm bushings tomorrow, beacuse they are shot and rusted as hell.

For the drivetrain i bought a 15/51 sprokets so i can cruise at 90km/h in about 6000rpm and the top speed should be around 135km/h according to gearingcommander website.

Lastly i would like to ask, is there a way that i could increase my revs to about 11k rpm? Right now it maxxes at like 9.5k and dosent sound the best.

All the feedback is greatly appreciated.

I forgot to add that I use this motorcycle as a daily driver and as a dirt bike on the track. Its really good on the track but my suspension is too soft and I cant jump with it.

@SpookDog that would be the thing if there was a good electrical scheme of my 4bl 1997 bike

@SpookDog i searched a bit and found my bike is actually yamaha dt 125 rn 1997. The rn model is restricted to 80 km/h and there is almost no info about that bike.
