my 500af build - October 21, 2013, 07:13 PM

Always wanted a 500af, started with 02 cr250 and 91 cr500 donor. Did all of the work myself except the frame, found a great guy in Illinois that does amazing work - theres some pretty shady guys out there doing conversions but his work is AWESOME - he also races and is a professional welder. I have been doing some testing and just installed a decompression valve, two acl surgeries kind of demand it.





feels like a ferrari!!!

These are really cool. Is it really expensive if you already have the motor and frame?

I just depends on how much time and money you want to put into it, you can buy a new service honda for around 12k... If you do it yourself you have to decide what you want to put the 500 in first, I wouldnt recommend a gen 1 or 2 cr frame for obvious reasons... I have wanted one for a long time so I spent a long time researching it... a lot of time on cr500riders.com and came up with my own design that is pretty basic, the 02-07 cr250 frame is absolutly great, turns great etc... the motor was horrible, hondas attempt to kill of the two stroke imo, lol... I plan on getting back into mx instead of just racing in the woods and am a pretty big guy so I wanted to make sure my frame was done right.

I have an 02 cr250 that I have setup for enduro riding. I really like the engine myself but thats just me, plenty of power for blazing through New England forest.

The 02 had a bit of a slack front end and there is an after market set of 22mm tripletree/fork clamps that tighten things up.
I just run a bit less oil in the front forks and that works well but not the preferred solution.
I had bumpsticks redo the front/rear suspension with racetech gear. New suspension is a must as the factory stuff was a mess.

Also, the airbox will leak water. They make an aluminum ring that seal the box to the boot.
Might want to try a flywheel weight, I have a 10oz on mine but with that much power bigger would barely be noticed.

Very interesting. What exactly needed to be done to the frame?

Don't listen to Jar, nothing is wrong with the frame.
The 22mm triple tree/fork braces are bolt on items, no frame mods necessary.

This is the item but there is NO WAY i would purchase new.
Like the advertising suggest, it places more weight on the front wheel so it does not washout so easily. This issue was a big discussion back in 02.

Have fun with you big 2 stroker. I had a 96 KTM SX360 and love big 2 strokes. I found my 360 was far easier to ride than the honda, but scary fast. Had a few high speed wrecks in the woods on that thing! LOL

the bike feels pretty amazing to me but I need some more seat time, the 500 motor definitly increases the weight on the front so will have to spend more time riding it the way it is,

Nothing bad about the AF, the KTM chassis is just a easier swap.
