That's common sense, more gears faster you can go same with cars. A overdrive tranny will outrun a car without OD because there isn't another gear to go into
Correct. on a 3-speed you typically get a 30% under drive to a 30% over drive, with 1:1 in the middle.
Some 5-speed internals may be higher, 35%-40%, but in relation to speed it's where that 1:1 ratio is that determines top speed. I usually set 1:1 @ ~35mph at peak power rpm.
Vroom-Vroom bud, gears rock on an MB ;-}
And From what I was told the 66/80 actually are the same thing but in the United States measurements make it a 66 and Chinese measurements make it a 80.
Whoever you told you that is an idiot.
Cubic Centimeters is friggn' volume math.
For a cylinder it is simply Width x Length.
What the Chinese do is measure the entire length of the cylinder, and not the real volume with the piston in.
This is simply to overstate displacement size for marketing numbers and that throws all comparison tests off.
The actual real volume DISPACEMENT with piston in is 66 Cubic Centimeters in the known galaxy, calling it anything other than what it is shows a disregard for facts and I discourage that when I can, as should you.
THERE IS NO SUCH THING AS A CHINESE ENGINE WITH 80CC DISPLACEMENT!
THE PISTON ONLY DISPLACES 66CC OF VOLUME WITH PISTON MOVEMENT LIKE EVERY OTHER ENGINE IN THE WORLD IS MEASURED.
Sorry for the rant, but I get questioned at times when I post a bike for sale
@66cc and get asked if I can upgrade it to an 80cc like everyone else posts.
I say ENOUGH of the 80cc BS and the end of 66/80cc advertising!
It's friggn' math! It can't be both!
