That is way to broad of a question. Rider skill, weight and other things will come into play. It took a ported banshee to beat my 700 last year, and it just had a hotcam stage II cam, PCII, an intake and barkers. With those mods it ran dead even with RIPPENS FAST play ported 4 mil, (Jameys bike is not set up to race though, more of a hillshooter). Now with the BIG megacycle cam, new piston, TB bore, port work and bigger valves on my 700 it is gonna take a stout shee to beat it... Like these guys are saying, the 700s are no joke.
