well, I guess I'm a little shocked. I found out today that my 98 500 goes 125, and feels like it STILL wants to go faster. I gotta regear this thing so I'm not doin that kind of speeds. -1 up front oughta do it nicely. I dont recall any 500R having gone 120+, seems to me they topped out at 115, unless the weather was just right, or I shed enough weight and stuff that slows it down. I have no clue honestly.
