Cr500

A CR500AF in the making.. This will take a little while to do so bare with me for updates and i will document my build.... when funds allow me i'll do a little more....

First you take this motorcycle


Are you mad? No way in hell i'm chopping a thing of beauty like that up. No i've decided to take that bike to my grave.... Instead i have opted for another option. Unfortunatly it will cost me more money, seriously it would be blasphamy to part such a fine peice of motorcycle history


Over the last few months i have been compiling a few bit's and peices to make my project finally a reality.




So far i have poured a couple $$$$ on the engine, this includes Brand new crankshaft and cylinder. I will be running a wide ratio transmission.. I will document my engine rebuild also...



This wont all happen unless a have a motorcycle to put my new engine into, Luckly here's one i aquired earlier. It's a 2007 cr125. Very low hour bike





I've painstakingly been trying to determine the best method for a 125 conversion, after doing many many hours of research i have opted NOT to convert the 125 chassis due to the heavy modifications required to do the frame.


Leads me to the next part, i have just purchased a cr250 frame. This is 2006 model... These frames are the same 02-07... Luckily everything will bolt straight over from my 125...








stay tuned

Forgive my ignorance but what are you doing here? I couldn't follow.. Are you putting the 500 into a 250 frame? If so will you keep the old 500 rolling chassis untouched so as to not 'waste' a classic bike so you can put the engine back in one day if you want to?

Interesting thread.. I will stay tuned!

Red1, the thought crossed my mind, too expensive. Also the gen3 250 chassis makes for an easier conversion...

Nice work, coley. I will admit to cringing when you posted the pic of you CR5, but building one from scratch is Teh Win.

Personally, I've been wondering about building a KX500SF (using an 03~07KX250 frame) but then I figure that I'd be perfectly happy with an 03+ KX250....

This entire thread makes me happy. If you need any help for bits Coley, give me a call! I like any two-stroke project.

Really interested to see how this goes Coley. Happyish with my Service Honda based on a 2004 CRF250R frame which I bought as I lack the fabrication skills.
