When i return from my deployment I am going to be getting new tires and possibly changing the sprockets. I plan on michelin pilot powers in 120/65 front 150/60 rear. From what i have gathered to stock sprocket gearing is 16/41 for my '03. I was thinking of going maybe 1 or 2 teeth up on the rear or dropping 1 tooth on the front. Would it even be worth it? I've been looking at this spreadsheet someone made and it almost doesn't seem worth it. Would the acceleration difference be noticable? I would still like to be able to do aprox 120+mph and all of those combos keep me at that. From looking at this spreadsheet and playing with some number it looks like the 16/43 combo would suit what i am looking for but i'm not sure if i would even be able to notice a difference to make it worth it. The 15/41 gives me what i look for but alot closer to redline(11k). I'm having a hard time deciding. I'm sure droping a tooth up front would be noticable but i'm hesitent because of the reading i've done it says that it will wear out the chain alot quicker. Would it really be that bad? Just looking for some input here from the experts. Thanks.
