2012 CRF500F---whoa, what?!
Posted 03 February 2012 - 01:01 PM
Curious, anyone know if this is merely a punched-out CRF450, or what?
What about the 2012 CRe125 2T ?
Heck, I did not even know that Honda-Montesa was "building" anything but the usual trials/dual-p stuff...maybe this is a 'testing ground" for American Honda, anyone know?

im building a crf 517 from a 2009 crf fuel injected bike the crank is being done with a longer rod to keep the rod ratio .
The longer rod would suit flat track and road race apps too with the stock bore and strokes.
Who is doing the rod?

I recently had one of my bikes punched out to a 490, which was almost the biggest I could go without increasing rod length. i could have increased it to 500cc but would have use an iron cylinder. I kept it at 490 rather than bumping it up to 500 because i wanted similar metals between the piston and cylinder so when I ride it in demanding conditions the expansion rate between them would be about the same and minimize the chance of seizing it. The bike still handles like a motocrosser, but with extra hp, which was my goal.
What I like about the four stroke motors is you can really personalize them to how you ride and the conditions you ride in. There are so many variables and things you can do to them its just like ordering off of a menu. Along those lines the heavy feeling I mentioned before on some of the BB kits I rode can be mitigated with extensive work. But it almost becomes cost prohibitive for the recreational user at that point.

That original site has a 2012 crf300r. I would love to have that.
why not take your current bike that is allready set up to your liking and add in a BB kit?
