......sold my second 1000rr on wed.....WAS thinking of quitting riding forever-----but 4days later, changed my mind and picked up a 05 RC51! its bone stock with about 1000miles on it! my comparison to my 06 1000rr with mods (arata pipe, tuned pc3, b&m intake) Handling: RC51 Power: 1000rr Tq: Slightly RC51 bottom line is, TWO TOTALLY different bikes! the LITER power of RC51 coming from a moded 1000rr is non existance IMO. i havent taken it in REAL twisties yet, but rc got stock dunlops 208s now...while RR had stock Diablos. oh and RC51's seat sux balls and hurts my back/butt after 1hr of straight hwy riding. RC51 has no clock also....and runs hot!
