I need a triple tree for a 1989. I requested and purchased a triple tree recently. It turns out it's the wrong one. Triple tree facts: the triple tree I need turns out to have the same lower as the 1200, but the upper (on the backside will have the casting numbers 1NL) will facilitate the second gen need for a vibration dampener system. The important thing here is, lower half of triple tree fits both 1st and 2nd gen. Upper half of triple tree has casting number 1NL and has bigger holes to facilitate the vibration dampener system. So, bottom line is, I need one for the 2nd gen. Look for the "1NL" on the under side of the upper and that will be the right one. It's not very distinct, but the old style is cast with "26H".
