-1 front +2 rear.. I did this and it made a difference but nothing to crazy rpm sit a little higher but nothing crazy. Lost a little high end but nothing i will ever notice b/c i dont plan on maxing my bike out
Is it true that when you change the sprocket sizes.. example 530 to 525, it increases speedo error?? My 03 gsxr 600, ever since I installed the new kit....speedo is way off!! and I definetly notice the slight rpm increase.But its all good considering the acceleration gain!!
It's not going from 525 to 520 or 530 to 525 that changes the speedo, it's changing the tooth count on the sprockets. More importanly (I think) is the size of the front one because that is where the speedo drive gear and sensor are. But the problem can be fixed for about $100 using a "speedo healer" or "yellow box", which will recalibrate the speedo for your gearing changes.
I just went with the 520 conversion. -1F +2R. I still haven't tested it out because I have a few more things to do. From what everyone has told me...you WILL feel a difference. Go with MotoMummy.com awesome prices and ships in no time. Good luck brotha
the sprockets determine your final gear if i'm not mistaken. Divide your rear by your drive sprocket and you get your final gear ratio.
45 divided by 15 is 3.0. so 3.0 is your final gear ratio.
3.0 is the number of rotations it'll have to turn in order to turn the wheel once.
So once you kinda play with numbers.. you kinda see that the back is less drastic of a change per tooth vs. the front sprocket.
Steel is also a heavier choice vs. aluminum, but doesn't wear out as fast.
Steel 4tw imo.
Knowing this you can kinda get a feel for what you want to buy. I'm in the same boat and have done a bit of research on this and my friends r6 forums. Lots of info out there, and i recommend knowing as much as possible.
