longer range cruising needs...

THATS because your 5th gear is higher than the HD 6th gear and I get around 45mpg on my 250HP Roadster
 
 
I can't say yet, I was to go on a 1500km ride last weekend but going this coming weekend. I am hoping my bottom does not get so numb and I can ride longer.
I think a good rub-a-dub by a pair of female hands would do wonders to a numb bottom , after a day of riding . I always try to stop my day riding in places where massage parlors are available
