1 down = ?
ok everyone says something diff about what 1 down in the front is = to going up in the back . i hear guys saying it = 1 - 1/2 up in the back i heard 2 -2 1/2 up in the back i even heard it = 3 up in the back so what does 1 down = to how many in the back for sure ??? anyone know the right answer to this ?? and why there right ?
thanks .
thanks .

Example 1, close to stock gearing:
15 on the front, 45 on the rear equals a 1:3 ratio. A -1 front would in fact equal +3 in the rear.
Example 2, Big rear sprocket:
15 front, 60 on the rear. Now the ratio is 1:4. So now that -1 would equal a +4 change in the rear.
Example 3, exteme parking lot stunting gears:
14 front, 70 rear = 1:5 ratio you get the point by now

Re: 1 down = ?
i agree with Kyle, well atleast -1 front is like +3 rear.. for yer 900 get a +5 will make some difference and when yer read ycan always do a -2 in the front and it'll be like a +10 rear for yer slow stuff..

Re: 1 down = ?
Not quite understanding you guys saying "going down 1 in front is LIKE going up 3 in the back"
Are you saying if you go down in the front, you have to change the rear spocket +3 ?
I have a stock 04 R6 and hear it's common for people to go down 1 in the front to a 15 tooth...are these guys changing out the rear as well? Or it's LIKE going up in the rear? A bit confused...

Re: 1 down = ?
someone answer this for me just a simple YES or NO i dont really want an explaination just yes or no
if you have two of the same bikes but one bike you go -1 in front and the other you go +3 in rear is the power and everything the same???

Re: 1 down = ?
i disagree....here's my
although the ratio may be the same,
a smaller front sprocket will increase torque.
a larger rear sprocket will cause the wheel to rotate at a slower speed and lower the speed at which the engine's powerband starts.
example 1: if you were to leave stock rear sprocket and only go down 2 in the front, it would not be equal to going up 6 in the rear.- your top speed would stay very high, but there would be alot more torque from the engine making wheelies easier and making the bike much faster off the line.
example 2: if you were to leave the front stock and go up 6 in the rear, again it would not give you equal results to 2 down in front.- your top speed will reduce because the wheel cannot rotate as fast anymore and the rpm at which your powerband kicks in will be reached at a slower travel speed.
either way or a combination of the two ways will make wheelies easier, but i belive that they yeild different effects/results.

heres my for some reason 1 down on 900 RR dident do much for me ,but when i went up 3 on my gsxr it made the world of diff . i know there 2 diff bikes but why did it seem like that for me with 3 up on gsxr i could gas it up in 3rd , on my 900 i have a hard time geting it up in 2nd with the one down .
