Good question! The C14 is lugging a bit at 65 mph going uphill or into a head wind because it's only turning about 3K rpms and the serious torque starts kicking in around 4k. I may be able to get higher gas mileage in 6th vs 5th above 80 mph, I just have never been in a position to do any good comparison testing of the higher speeds. I think it is save to say that the mileage will drop considerably in either gear at high speeds, the C14 is pretty wide in the front with a huge radiator and is pushing a lot of air.At first I thought: "That's the point of a sixth gear 'overdrive', to be tall" and wondered how it was actually hurting gas mileage. Makes sense though as the C14 engine tune is biased more for upper RPM HP than low and mid range torque so it's 'lugging' a bit at 65mph. I wonder what speed the Kawa engineers had in mind when figuring the ratio? Autobahn?Absolutely, the 6th gear is so tall that it reduces gas mileage. The overdrive 6th works great on a downhill or a tailwind but about 80 percent of the time I can get better gas mileage by riding in 5th.....which is lower geared than the FJR's 5th gear.MCRIDER007,It already has 6 gears but needs a lower 6th gear ratio that you can actually use most of the time and....
Do you feel the C14's 6th gear is too tall?
Mr. BR
If you want to compare gear reduction ratios, 6th gear is 3:40 and 5th gear is 4:08........ 5th gear on a GEN2/3 is 3:92. I think a 3:70 would be a good ratio for 6th.
