how to build RM125

[Marc.com]

this is one of the best I have seen recently, built for one of the Coral bosses in the USA, but never delivered, check attention to detail

Damn it Marc did you have show that!
I have a 125T sitting in the shed thinking what i might do with it as I've nearly finished the "C"
Along with a YZ80H,2 x YZ80K's,2 x CT90's,SL70E..........

Heres the T




The big end seized and the previous owner had an RM100 as a bitsa and used the crank and top end into the 125 cases.
I have all the original bits,just need to rebuild the 125 crank and re-fit to bring it back to a 125 (one day)
cheers...mario

Looks like you've got two different bikes there MarcFX (the one in the air). Regardless I do like the detail on the top one, I like the drilling in all the hardware and the fresh re-built look.

actually they are come to think of it.

I am working on 125C I scored for $400 the other day, motor is original bore and looks good, the rest arrived in bits.

Monaro, what are those rear shocks, Progressive? Just building an RM100 -using 125 forks and swingarm, unfortunately with the RM100 14" shocks it seems to be sitting too low and the 125 shocks are fecked... javascript:void(0);

shocks are too short, try 15.5". You are limited as to what shocks fit the stock frame and swinger.

Hi loydee,the shocks came on the bike.They are dual rate spring MDI brand and measure 398/400mm eye to eye.
As marcfx said you will need around 15.5 or 390-400mm and if running the body at the top you will need shocks with the extended mounts at the bottom to clear the s/arm.
I just measured my rm100x shocks at 367mm and the rm125c shocks at 372mm.
I wouldnt mind putting original T shocks back in mine if i can find a decent set.
I tried my C shocks but yeah too short and the bottom shock spring end hits.
