I was just wondering what are the spec. diff. between these years of the RR

 

Its mainly weight and HP. And different color schemes. Sorry, but I dont have any specs.

 

Yeah as far as minor differences that Deimos specified they are the same bike. Almost any part either stock or aftermarket will fit an '03/'04 and visa versa.

 

'03-'04 were identical other than color changes. While the '05 looks almost the same as the '03-'04, it has been completely redesigned with lower weight and higher midrange torque. The front forks are now inverted and the front brakes are mounted radially like the 1000rr. The '05 weighs about 15 lbs lighter than the '03-'04 (about 425 lbs wet) and has around 106 rwhp (compared to around 103 on the earlier models). Quarter mile times are in the mid to high 10's and top speed is approximately 165 mph. Cosmetically, the '05 has only been subtly changed with redesigned air intakes and rear body work being the most notably different.
