Fascinating. I never would have believed that a battery could save 11 pounds!

 

What swingarm?

 

Great find....easier than shaving 11lbs off my gut!

 

You won't be able to tell any difference in performance, w/ these upgrades.

 

Who makes the swingarm?

 

Try telling that to drag racers!

 

Exactly!!! When I use to drag race quads on dirt, the general rule was take 15 pounds off and you would gain a 10th of a second. And that was only running 300 feet. Less weight equals going faster!!!

 

metmachex quality is excellent about 20 lbs weight loss

Hey, I've done my share of drag racing, @ the strip and on the street. 30# (about a tank of gas) off a 700# bike is less than 5%. And yes, you'd need a precision timing instrument to detect a difference in the 1/4-mile.
