why is 6th gear so tall?

[pkoko]

The difference between 5th and 6th gear is really small. Why didn't Yamaha make six hear a cruising gear with much taller ratio? Like the corvette

Probably because this bike gets better gas mileage at 6-7k then at 3-5k.

I just find that hard to believe. There is less frictional loses at lower rpm. Why do those members who change the front sprocket get better mpg?

I wondered the same thing although the mpg is better about 6k to 7k

I seem to get better mileage as well in the 5k-6k range than 6k-8k. Haven't put on the new sprockets yet (that happens with the next tire change, and service, I figure at 16k).

For whatever reason, and YMMV, the 6R seems to like the lower rev range -- less buzzy, and (for me) better mileage. I'm rarely over 7k, unless I'm pushing it on a highway, or passing in low gear...

The 6R get the best mileage on my ride around 6500 RPM (less fuel % on the data logger)

We don't gear up to rev lower, we gear up to go faster at a given RPM! LOL

What ^^^^ he said!!!

so what you guys are saying is, 30 miles to the gallon isnt good gas mileage...

 

[Cerebus]

30 mpg is horrible for this bike IMO.

check your:
tire pressure
air filter
change gas stations

shift at 5-7krpm....
lean forward, not straight up

etc. etc. etc.

MAy be a bit off topic but....I got my bike with zero miles and a full tank. Im keeping rpms right at about 6200 on freeway which has been 90% thus far and I got 134 miles to this tank. I rode twisties today keeping the speed at about 50 so 5k or so but varrying from 3rd to 5th gear and only got about 100 miles...so meh
