hey i just bought a used 06 250 with only 2000 miles on it. i really enjoy the bike,the fastest i went is prob about 65. i was just wondering what rpm should i bring it up to before it kinda get outa hand? cuz i dont´ wanna mess up the bike since it sound like is pushing it when is up to 65 mph, can anyone let me know what the limit is and can i go up to 75 constanly without ruining the bike??
