wouldn't -1/+0 still bring the bike to roll faster than stock though?
It's somewhat humorous that I am debating so heavily over 1 tooth in the sprocket (now considering -1/+0 vs -1/+1) ughhh decisions... I just want to enjoy my bike and I hate messing with things like this sometimes in fear that I'll change things to something I dislike and spending the minimal money I have in the process.
Like I said brother, the -1 front sprocket for your front and oem chain is a CHEAP MOD. One of the best bang for your buck mods possible IMO. Try that if you're so indecisive!
-1 will lower your minimum speed from stock. -1/+1 will also reduce your minimum speed in 1st gear as well, but a bit more. -1/+2 is just too steep for that bike and even the 3rd gen R6 IMO. It's much easier on the clutch for race launches, but that's about it in my book as far as it goes.
-1/+1 is great on my 02, but when I run a 190 on it I like it a lot better, but this is really cause that bike wheezes up top near redline unlike the newer models do.
It's all up to you. If you haven't done a lot to the bike, and this is what you're buying and you don't buy a lot of shit often, debate it for days bro. Fcukit man, I would too. Ask around, text your boys, call a friend, PM Melk-Man, see what he says. He had one REAL BAD ASS 05, so check with him and see what his opinion is.
The more you go with this shorter gearing, the worse your gas mileage is as well as it reduces the life span of your engine as well. That last one is something nobody ever mentions, but it's a fact that operating at higher RPMs all the time will clearly and surely result in faster wear...
Change only as much as you think you need to make the bike more enjoyable without killing it's range, rideability, speedo error, etc. There's a lot more to consider IMO. But I can surely tell you that with -1/+2 and even my -1/+1 on the 02, I am in like 4-6th gear all over town so I don't sound like I'm in a fcuking race at all times.
Good luck pondering!!
