Sometime back there was a post where 999R exhausts were discussed. I never did find out why the silencer on my 03 999R said "for race use only". I suspected like the Desmo (in a remote and small kind of way) the exhaust was packed separately in the crate and installed upon delivery. I spoke to a dealer principle and he confirmed the bike came with a separate silencer, CPU with a stand and cover. The silencer was lighter than stock, had no cat and weighed less by approx. 8 lbs (not sure on the weight difference). The real bonus was the increase of 3 to 5 HP. So with the HP measuring system used in 03, my bike was in the 142 to 145HP crank HP range. Not to shabby. He also told me the 03 bike came, less the tank with a full carbon fiber body. Apparently the newer machines lacked some carbon fiber compared to the 03, on the other hand I know the 05 had the magnesium valve covers and the braced swingarm in black whereas the 03 did not. Some of you know I recently updated my bike when I found a rare set of magnesium valve covers through BCM. Funny how that one upgrade seems to make such a dramatic difference, especially for those who know the 999R bike.
