and most of that was the electronic reverse
Even if you go to the DD lite, it's only 11 lbs off (plus servo). MBMS is correct in that figure of 8 lbs, it's on the low side of 7 plus the servo which was about a lb if I recall.
You can see the figures right on bdx's website.
"New for 07' - UP M's and Crossfire is our Diamond Lite Drive system that takes off a true11 lbs (07'-08') 4lbs (09') of unwanted weight"
If you're going to do weight loss mods, weigh the old compared to the new so you can have a real comparison. The advertised numbers are all rounded up from any of the aftermarket companies, if you listen to them, and you have 15 mods, you could be off by almost 10 lbs. In all the mods I did, there was one mod from Bdx that saved a little more than they claimed (xxlbs+ 5oz if I recall, can't find my list right now) all the rest were very close or rounded up.
