it's the big bottom end torque I like on the RFS engine that's missing from the SX engine...........
up to 7 k the xc has a strong advantage ?? or am I reading this wrong
There is no way. The 477 will have more power across the board. Im willing to bet from my experience that the curve will be identical just about 1-1.5whp less on the 450. Any takers on my bet?? LOLI have read the same thing. They supposedly have the exact same peak hp. The difference is how the 450 gets it there. They say it is way more expolosive off of the bottom and just rips it to the top, where the 505 is more of a smooth linear power curve. We will see though when the dyno's start pulling both of them.

Both bikes have modded stock exhaust and modded air box. Both jetted properly. This just showed the difference between the two. Pretty big difference. Its cool to see. They both are fast in their own way. Ill keep my sx. LOL
