Been playing with gearing all day. The stock for my bike was 15/42. I tryed 15/38 and this seemed much better for every day use up and down the motorway even blasts. A freind got me a 16t for the front so now im running 16/38. The bike seems to pull it pretty good up most hills (tho you do have to drop down one if you have to roll the throttle for anything) and will easly run flat out on the flat if you give it some stick. Is anyone else running gearing like that or am i well over geared for this kinda bike? lol first gear feels like my rc45 now.
