Hey guys. Its that time of year again. Last race of the year was this past weekend so its time to tear it down and refresh. I am not sure how crazy this build will get but I will be going completely through the bike getting some powder coat done along with some other odds and ends. As far as when I will be completely tearing it down I am not 100% positive on when I will be doing that. I am working on building a data acquisition system for it so I can tune for some engine mods, the pipe and possibly a different fuel. I would like to get at least a prototype done of that before I completely tear it down. I hope you guys enjoy and can provide me with feedback good or bad and maybe some ideas along the way.
Here are some pics of it after the last race
And some during the Initial cleaning phase
and lastly this is what it looked like at the beginning of the season

The Shop
On a good note the front brembo brake system I bought showed up today. It is brand new with 0 Hours on it. It did not come with the bar clamp or hardware which sucks but oh well. looks like the line will work and when using the top bracket bolt the pads line up real well on the stock honda 270mm front rotor. the bottom hole however is not even remotely close but its better than i expected. So I will either have to rework the brembo mount or built a new one in solidworks and have it machined. I will most likely have to design a new one because getting the bracket to center on the rotor at had to add 2 washers. Any way here are some pics.
The KTM line seems to fit pretty well so as of now I dont see a need to swap it.
Here you can see just how far the lower hole is off.
2 washers were used to space the bracket and get it close to center over the rotor.

#1 Rode a buddies brand new KTM last year and the first thing I said when I got off the bike was wow I really like the front brakes. This was when the idea came about in my head but then I shrugged it off and went about my life.
#2 I was planning on upgrading to a braided line and oversize rotor this winter but I also plan on building a second set of wheels so I hopefully keep a nicer set of rims and tires for racing and an ok set for practice. This means I would have to buy 2 oversize rotors instead of 1 or I would have to swap mounts when I did rim changes and would not be practicing with my race set up.
#3 I have an 08 RM 250 that I have put my 17' CRF brakes on a few times and really liked that setup. I had already planned on doing some sort of upgrade on that bike (it already has an oversize rotor)
#4 I got the complete front system off a brand new bike with 0 hrs for $150. This is most likely the biggest factor of the whole swap. The way I see it for $150 I got a completely new brake system for my CRF plus inadvertently upgraded my RM brakes, saved myself from buying an oversize rotor kit and second rotor for my spare wheels, and also saved myself from buying a braided line for the CRF because the Brembo comes factory with a braided line.
#5 Its a Brembo haha
I also need to correct myself from an earlier post on the stock CRF brake size, it is a 260mm not 270mm. Not sure why I had that in my head.
