CR250R Conversion to ATCR250R

[atc250r18]

It's not that I want to copy you because believe me, I want my creation to be a one off that no one else has. It's just that your triple trees will fit my project perfectly. I don't want a kit or anything just the clamps. I've got my own plan that I plan on using for my swinger but I thought it would save some time to already have the clamps made up. If you don't want to share your stuff beleive me I completely understand. I feel the same way. Beleive me I'm not trying to push a conversion kit on you or anything like that. I just want a modern trike like you. My old 250r tells me that she's tired and wants to take a brake but she's all I got. My motocross stuff ain't got nothin on that ol girl. I'm just lookin for somthing great to feel a void in my heart. You know how I feel.

I'm sorry if this is being taken wrong.....I am NOT against other people having one of these....I was kidding more than anything. I doubt that the market would be flooded with conversions, even if there were a kit available. I have been thinkin of building a new set for this one...modified and tweaked a bit....and if I do, I can list these up for sale. If ya go back and re-read some of this thread, you'll see the guy who machined these for me ISN't going to be able to do any more any time soon. He is too busy with other things.... I am checking onto some other options. A friend a couple miles away has a small end mill at his garage and I may just have to do the next ones myself. We'll see.

As for the MX capabilities of this bike....I only got out on the big MX track for a few laps and kinda hit the step-up jump half and half. Too short to clear the whole thing, and too far to land smooth. Bottomed kinda hard. My fork seals are blown and leaking, and it is obvious that the long swingarm is making the rear shock too soft for any serious air. I kinda figured the rear would be soft, but that is fine for MY riding. I don't go real big, and I can't/don't really MX. With the front reworked, it will be a fine trailbike, and excellent dragger. As it works now, it would feel sweet out in the open Dunes.

Now, to build one for the MX track? I think with a shorter swinger, a slightly modified subframe (couple inches lower) and more/easier turn in the front end, it would work ok. Later.

Out Standing,How much would you say it weighs?and what is the stability like?
any more stable than the 86 ATC R?
I work on bikes all night at school (MMI)and dream of this sort of thing constantly.
Although I am not a fabricator I dream none the less and considering the amount of fabrication involved I doubt I could pull it off but dont know untill I try .
Exellent job ,I would definately send pics to HONDA.

Bump. Anyone have a vid of this thing MX'ing? Where is it now?

[350Xhilaration]

Suspension was too soft for MX. Blew the fork seals the first couple laps at TF 06.

Where is it now...parted out all over eBay. :cry:

Only vids were of it at TF drag racing and other vids already posted.

[SpeedBump]

Wow..long time no see on this one. Cool. I don't have any video of it MX'in. I did rip it around the big track at TF the year I had it there. It really wasn't too good on the track. With the stock subframe/seat setup it was a bit too tall. The steering was not the best either. That was my first crack at it and I didn't get it right. It wasn't horrible, but far from where it should have been. Ii also planned on doing more drag racing, so I built the swinger pretty long. That also contributed to its handling issues but mostly made it was really soft in the rear. It was a fun build.

It's where abouts now? I had some offers to buy it when I decided to sell, but I just couldn't get the money outta it that I wanted. In the end I kept some of the stuff that I could use for my other rides, and the rest was sold off in pieces. The triples and swinger was sold to one fella who said he was gonna build one, but I never heard from him again. It would be nice to find out. Thanks for the bump.

wow, that thing looks amazing...too bad about getting rid of it

but i guess now you have room for more projects!! haha

[SmurfanCoke]

Just spent the last hour and a half reading this whole thread, absolutely f*****g amazing, your dedication and reluctance to leave a half-ass job made for a very tasty machine.
Big up, an good luck with the next one......

[WLL]

I also here that you are supposed to do a topend like every 30 hours or something on those?! I mean come on, whats the point of a four stroke if you have to give it even more $$$ and maintanence than a 2 stroke.
just reading this thread now and wanted to say the point of the 4 is so the dealer can make more money from the riders. its called corprit greed:(

[WLL]

Maybe you just won't ever understand why most folks here think that this is the project to watch.

To each his own.

I think its awesome for all the reasons stated above.

Keep going speed bump!!X2 im fkn :drool: over it

[gomer202]

I know this is an old thread but does anybody know what year that cr250 is I would like to get some info on building one

[falloutboy]

K, so I'm hopping on the necro-posting bandwagon real quick...

I just spent the last hour reading this and get to the end, only to find out it was parted out. :rolleyes:

It was like watching the 6th Sense and finding out at the end Bruce Willis was dead all along! :wondering

I did notice the rear fenders and seat sat too high. Should feel slightly more chopper-ish, IMO

[250rRoostmaster]

Damn dude that's pretty nice!!

[TtownJoeShow]

Un F****** real!! good job!!! do you have any for sale??!! lol

[Atc GuY]

AWESOME build.

I'm not gunna start a 4t/2t debate, but I can vouch for a guy that did minimal maintenance (oil changes whenever), was on the original valves and everything else in the engine, and had well over 300 hours on his 08 yz450f. The guy beat the crap out of it, it spent most of it's life at 12 O'clock it finally go so low on compression that it ate all the oil and locked up. It unlocked but sounded bad, and you could crank it by hand. He figured it didn't owe him anything. It's been sitting since.

The choice to go with the aluminum honda frames was a good one! The 02 CR I had a while ago was a great platform and responded to turn well.

LOL. This is my good buddys build. This bike was at TF06. It did great at the drags. Looked unreal. The brakes were so good I remember it doing 90degree stoppies. A little top heavy. But that was the only downfall. Speedbump had some mad hours into this build. He is a true undercover Scientist in my eyes. Super smart and creative!
