I am not sure where it all went wrong. This project started innocently enough a father's desire to ride with his eleven year old son, to show him the ancient riding grounds of his youth, to point out the petrified track of a DT-1 yamaha, and over there the tracks of a pack of 400 Husky's. And there, in the parched desart soil, a scar gouged from the earth by a wide eyed KTM 495 racer! O for the smell of casteroil again! Well, first we need bikes. So after some reading I buy a new WR250F, and ride it a day or two. I tear it down. I order an over size tank, the suspention is sent to Factory Conection, the tires are scraped for maxxies and heavy tubes, we do the gray wire, the air box ,YZ cam and cam timing , jet kit, FMF Pipe, tall seat foam, pegs, grips,bars, tripple clamp, Well, you get the idea. Now for my sons bike. I start looking for a good kids trail bike. Something thats easy to ride with a tuff reliable limited fourstroke motor and state of the art suspention and brakes. We will need lights front and rear so he's not run over. And electric start. We need a WR 125F! What do you mean thay don't make one! A TTR 125E? Well thats a good place to start butt, and here are the pictures. Injoy!

Nice project... very good looking aluminum fab work - the bead on the rear master cylinder looks good with that paint on it. You might want to come up with a better hose routing for the rear brake- give it another inch or two of slack. It looks like a pinch waiting to happen on a large compression of the swing arm with that hard bend.

Sweet looking, sure wish Yamaha sold them.:ride: Any engine mods? Or just the airbox, jetting and pipe?

Nice, clean bike !

I would look to getting a frame cradle on there before the frame stretches.

Search the forum, it's the first mod most people recommend.

Just had a closer look at your master cylinder bracket & brake lever.

I couldnt seem to get the YZ lever to sitcorrectly, so I made a new one from scratch.

The bike is being stripped in the summer for powder coating so at the moment it's just painted matt black to keep the rust at bay.

I did the front end first (after reading some posts on TT) swaped it out for an new 05 YZ85 unit I found on E-Bay, wheel, brake, forks, T. clamps and finder. I added a Baja D. lighting kit and Moose racing hand gards. motor work, BBR stage 1 cam,Pipe,Jet kit,air box mod.,BBR air cleaner. On the rear end I used a new LE rear shock and aluminum swingarm (from TT parts. The best price around !) I cut the arms off and welded on the YZ 85 arms, added a YZ 85 rear wheel and brake setup. Cut the brackets from a YZ 85 frame (E-Bay $22.00 + $32.00 shipping) R.Brake lever is a YZ 85 and a TTR125E welded togather. Thats about it. Ed...

Super clean bike, excelent job. Now thats how it should be offered from the factory. The only thing left to do is the big bore kit. Any plans for it in the near future?

No, not at this time. the motor runs sweet, and austin is eleven years old, so I think we will just try to rack up some miles here in the desart and across the border in northern baja ( only 30 miles to the south). I do plan to fab a skid plate. I allso bought a set of big wheels, but I think he needs to grow a bit be for we put them on ! Ed...

What year LE had a aluminum swingarm? I considering doing the rear conversion like you did.

Greetings. I am not sure what year the TTR 125 LE started using the aluminum swingarm, But the the helpful guys at TT Parts can find it for you. Thats where I bought mine. I did see one on E-Bay some time back. Ed...

I should have looked at our bike before I asked. Our 03 LE has a aluminum swingarm on it.

I'm totally digging on this conversion! While all the others I have seen are pretty dang cool in their own right... this one totally looks factory. I'm in the process of collecting parts for a conversion of my wife's TTR-125LE to something similar to this... I just hope it comes out looking as clean.

Thanks for the inspiration, Hale-Yes! :thumbsup:

I could not agree more, that bike looks awesome. I would love to do that but I don't think my wife would appreciate it like it should be appreciated.

Greetings. If any one wants, I will come with a price to fab up your swingarm for you. You will need to come up with the aluminum TTR125 LE swingarm and the aluminum YZ 85 swingarm, and send them to me, and I will cut/jig/weld/and paint them (yea, there painted with aluminum paint from the factory, so when you weld them up, you burn the paint) and send them back to you.
