Picked up an rm125 2004. In an ironic twist of fate this is my 3rd 04 rm125 ive owned over the years. Dont ask why, it just happened that way.
Its a little hammered, missing a few pieces, and dirt caked everywhere
The plan is to simply get it ready to just ride by replacing worn or damaged parts, fresh fluids etc. at this point if the parts works and functions its staying as im on a limited budget. if everything pans out ill do a full tilt built next year

tear down was the subframe and air box. the air box is just caked in dirt and oil. ill have this cleaned out nicely
silencer is...well...in need of attention. was missing about a 1/3 of the packing and what is there is soaked in oil and the mount was worn.
new packing is on the way and will have a shop weld on some new material
and picked this up off of ebay for a steal
the only thing holding the gas tank on was the retention strap but the bike is coming down
JB weld is not a cure all. both pipe on the right side were cracked and "repaired"
i ordered a set of used ones that were straight. Ill save these to send off for repair and bracing later on
And its all apart
im always suprised at what parts are missing, or worn, damaged or simply not attended to.
on this bike i am suprised none of the bearings so far are dry and actually have grease and only a handful of bolts have been seized.
Now that its all torn down, the first step back is to get the frame sanded and repainted
The Shop
DeCal Works Huge Plastic Inventory of UFO and Polisport kits.
Free shipping: VITALMX
Luxon 4-Post Bar Mounts
$189.95 - $239.95
Also swapped the rear spring for a heavier one and finished repacking the silencer
Ive gotten to a few other areas of the bike. I installed new brake pads and rotor up front and rebuild the master cylinder.
I installed a new Guts seat cover and seat foam
cleaned up the jetting, I leaned out to what PC recommended P: 40 M: 360 N:stock 2nd clip
For triple clamps, i needed to swap out the whole set to run oversize bars but I wanted to avoid dropping a lot on aftermarket clamps. Fortunately parts from other models in the same year range fit. I installed clamps from an 2006 Rmz450 without any issues aside from questionable clearance with the stops.
At the track I rode the first half of the day with the Fastways (lowered)
Overall they sit close to an inch lower and to the rear
The lower setting suited my legs better as i could grip the seat with my knees. Sitting was more comfortable and I felt more at ease in the rider triangle and the wider platform was noticed. The biggest issue i ran into was catching my toes in the deep ruts. I mustve caught them about 3-4 times, once going through a quick straight away (with ruts) that picked my foot up and one that really scared, caught my toes and pulled then down around the peg. After that i really tried to think of my foot position and had to focus on riding on the balls instead of my arches
For the sencond half of the day i rode with the stock pegs. First thing I noticed was my knees sitting higher, I felt a little cramped back on the bike. Once i was riding around when I was standing I did notice standing higher up on the bike, with this feeling I wasnt as worried hitting tall ruts as much or leaning the bike over on jumps
The Fastways are better than stock for their sheer size vs stock. As for the lower setting, Im not 100% on board with it yet but I have bad form and only put a little bit of time on them
This one is my sponsorship application photo on am 03 rm125
These two were on an 04 rm125 during a summer series. I thought racing a 125 against a field of 250fs in the novice class when i was a top 5 guy would be fun...it wasnt fun being buried off each start
I picked this 04 rm125 up in 2011. This one i regret selling as it was just before the two stroke craze really came back. I picked this up for $1000. It had been an amatuer race bike for a local kid so the engine was built well.
I used to kill it on starts all the time but today i was behind the whole way. It didnt matter much as by about lap 3 arm pump was bad enough i had to back it off to parade lap speeds haha. I at least had fun just pegging the throttle through the deep sand berms, but i would've loved to be fighting up front where i used to be but age and time away has diminished my skill. Goal is to at least 4 races this year to start.
Bike still needs some attention, sorting out the suspension settings, testing different parts, possibly warped clutch plates, and other small items

Ok, im picky most likely like everyone else here about tires. Im also on a budget which means not picking top level Dunlops or other models.
I've ridden every brand at one point, Dunlop 756s, Bridgestone m404's, Michelins Starcross, Maxxis and even Shinko's
so i feel i have a good pallet for tires.
I really like having my tires predictable and obviously have good traction which is what these have given. Other budget tires like Maxxis or Dunlop 952's I always felt lacked performance necessary for use outside recreational/OHV park riding. So far on Sand and Intermediate clay these have been solid especially when a pair is $130 on Amazon
Last race bike seemed down on some.power and when I did starts it was grabby/jumpy whatever. Finally opened it up to find flakes in the oil and it was silvery.
Plates didnt look too bad coming out, some obvious wear until I found this guy
I'd your wondering, if cracked and then shredded the missing pieces which explains the flakes
All in all two innermost fiber plates cracked and the basket has some notching which is no surprise
ProX sell a oem inner hub and pressure place and they are inexpensive... i ran wiseco basket and replace the proxX hub often
