Thanks Redpillar. I was guessing 4ish pounds and, yes - that's noticeable.

Mine's an 07 and has the analog cluster so I'm wondering if I'll lose a bit more due to the difference in the digi/analog stock clusters.

I was very impressed even with the Endurance model that I installed on my 400EXC. Ran off internal battery power alone and the batteries lasted maybe 2 years.

 

Maybe another pound or so?

 

I'd be very happy with a 5 pound weight loss overall. Plan on another 5 pound weight loss with the purchase of a new lightweight battery for next season. 2 pounds less on the 300R exhaust system and maybe 1 more dumping the rear inner fender junk off the rear. Maybe 13 less than stock. Add a couple for a skid plate and another 1 pound for the Tusk handguards. All in all - maybe 10 pounds off.

As a show of good faith, I'll see if I can lose 5 myself.
