any one know if the gears in six speed are the same as a five speed up till 6th.

another words is a 6 speed basically a 5 speed with a extra gear thrown in?

 

Not that I am aware of, if I remember correctly both 5th gear in a 5 speed and 6th gear in a 6 speed are both 1-1 ratios. Unless you are talking about a Baker OD6 gearset in the trans.

 

I've got a SE six-speed in my 06 Road King.The first five gears are exactly the same as stock,the sixth gear is an overdrive,completely extra.I use it only when I'm cruising at 70mph or better.Absolutely fantastic to be doing 75mph and turning the same rpm's as 65 in fifth gear.

 

sometimes yes, sometime no.

a 6 can be a "close ratio" with a 1:1 final

or it can be an overdrive with a .86 ( or so) 6th gear, 5th is a 1:1

andrews has charts as does baker drive train

andrews has a doc:

28_RatiosMPG-pg28.pdf

which I find very handy for ratios/rpm/road speed

depending on what you ride, what you are doing, overdrives can be achieved by a smaller rear pulley ( and doing away with belt guard) 65 tooth sometimes retains same belt ( had that on my evo bagger), 61 tooth requires a softail belt ( i have this on my FXRp)
or a slightly larger front pulley for overdrive

the new harley stock 6 speed is a 1-1 6th (just like the 5th in the older models)the make the primary and final drive ratios taller,and basically add a lower first,not low enough in my opinion.its worse on the 07-08 models the 09 up have a slightly lower final drive ratio,if your adding a six speed to a 5 speed bike i would recommend one that uses a true overdrive.

 

6 speed in an 06? Not a stock gearset, an SE gearset replaced the stock 5 speed, right?

 

Never heard of an overdrive in any sense other than the output shaft of a trans turning faster than the input shaft. A primary drive can be altered as can a final drive but that doesn't make those items overdrives.

 

Yes,I had the transmission gearset put in a few years ago and the sixth gear is a 1;86 ratio,really meant for cruising at 70mph or more.The extra on my engine is the 95ci kit which gives you the pulling power for the sixth gear.A real nice set-up.

 

in looking at my owners manual. On my evo ultra it says 5 gear is like 3.6 or something to one. Everyone says both 5 and 6 speed are 1.1 but my manual says something else. so what is it...IDK for sure

 

5 speed - ’85-’93 (except ’93 Softail) - stock 32T front / 70T rear pulley - 3.37 final drive ratio ( Domestic models!)

5 speed - ’94-’06 (except ’95 Softail) - stock 32T front / 70T rear pulley - 3.15 final drive ratio

the .86 or 1:1 ratios we talked about are the ratios of the transmission only

final drive takes in the primary drive ratios + tranny + rear belt pulleys
