ok, i am a c rider on a 2005 yz 125. im 14 and 5'7". i race new englend harescrambles. i try to stand up as often as i can and i do bad/ok. i usually finish 10th out of 14 with times usually around 10 minutes behind the average rider. ive had the bike for about a month and ive been riding for around a year so i dont expect myself to be very good yet but i have to be doing something wrong. is there anything you guys/girls do when you come to stuff like hills/rock gardens/logs/roots. any tips would be great.
