LOVE the 6th gear in my 07 RG. Like mentioned earlier. about 70-75 seems to be the sweet spot in 6th.
At 80 mph I'm running 3,000 rpm's (70 mph in 5th puts me at 3,000) . I like to stay in the 2,500 range which puts me at about 75 mph.

 

Isn't the six gear in the new transmissions still 1:1 ratio just like 5th in the old transmissions???? the screamin eagle 6 speeds were overdrive transmissions, i think thats the way to go...
