Newbie here! Anyone know what temperature range is normal for a 250r....just bought one...it isn't bored over at just pipe reeds...etc...bolt on addons.
This really depends on several factors, including how fast you are going, how much airflow you are getting through the rad, what type of riding you are doing. You could technically be anywhere around 150° - 190° and still be in a normal range, depending on what you are doing, for a stock cylinder.
