New Bike Project!! CRF230F Conversion

Hey folks. Attached are some pics of my latest project. It's a conversion of a 2003 CRF230F. Basically, my objective was to take a relatively mild trailbike and turn it into a less mild, but well suspended all around dirtbike. First, here is the bike as purchased a couple weeks back:


The firs order or business was to strip the bike down to get some of the suspension work started. First, I removed the forks to be sold at a later date. Instead, I will mount a much better set of forks off a 1984 CR125R. Then I took the rear shock off and sent it to Hlebo Bros. to be revalved and rebuilt:


Here is the difference in forks. You can tell the wimpy 230 forks right away (they're on the right):


To make the new forks fit on the bike, I had to have my dad machine a spacer as the stem on the 125 is about 5/8" longer than the stock 230 one. Here is a pic of the triple trees I mounted with the new spacer....looks NICE:


I had to completely rebuild the forks and lower them about 1.5". While I waited for fork seals to arrive, I installed a White Bros Intake, a White Bros R4 exhaust, and installed the Honda power-up kit (new main jet and needle). Here is the bike with those upgrades...looking nicer.....:


Forks are now rebuilt and lowered. Here is a before and after pic of the fork legs showing the difference in length:


Forks are now on and look great!!! Just a few more modifications and the bike will be complete. Also got the rear shock back yesterday and put it on. Here are the forks about 90% complete:


Stay tuned for more updates!!! And very soon, a first ride report!

Hi there,

I was wanting to preform the same mod on my bike i weight about 200lbs

and I have a couple of questions if that is ok

you said that you shrunk the length of the forks by 1.5" was that to prevent it from it looking like a chopper?

also what was the cost of the rebuilt forks? What did the do to them, I guess more than fork seals.

What weight oil did you use for them

Do the forks have taps on the top to allow you to let the air out of them?

Did you have to get other bearings for the crf's stem what did you use

here is my email: trademeaccountemail@yahoo.com
if you can please send me an email with you recommendation and any tips on what i can do to my bike to make it more robust without making it stupid looking.

Thanks for your time,

Blake

Hi there,

I have a CRF230F5 and i wanted to preform the same mod as you preformed although i have a few questions

why did you lower the forks by 1.5"?
is that so it didn't look like a chopper? what did it cost to lower the forks?

also what was the cost to rebuild your forks?

what bearings did you use in the stem? CRF230 or CR125?

I am really looking forward to preforming this mod as my bike a little bit small for me but i don't want a high maintenance bike and I like what you have if you can please email your recommendations on what you think i should do.

Cheers,

Blake
