Okay, now that I've ridden it, it seems like the bike is almost looking for another gear when I reach 6th. Recommend changing rear sprocekt a couple teeth to make it smaller? I am getting an exhaust this week, but I don't see that making the top end open up anymore. If anyone has changed the gearing to improve top end, what size sprocket did you go with? I use Sidewider sprockets Ti-Moly series on my off road quad, but don't know if they make street bike sprockets....any info please.

What top speed are you trying to reach? What RPM do you normally cruise around at?

I'm really not wanting to get to a ridicuous top speed, and as of now I am still breaking it in and maintain the speed limit for the most part. I just feel the bike needs a little more on the top end. The RPM's that I've been to thus far is around 6500 to 7000. Maybe it's just me and I think it needs to be opened up a little. I really don't know much about these bikes, so what I think I need may not be exactly what I need. I'm just going by the way it feels...but that could be the breaking in.

Right now im running -1/+3. My speedometer is off by 15mph. When im on the freeway my rpm's are around 7-8000 cruising with traffic i think around 75 or 80. I've only had an R6 for a couple of months now but i can role on the throttle in sixth gear from around 60 and it will bring me all the way up to 170mph really fast and really easy. I would just stay with the stock gearing if not increase the back a couple. :hammer

well i can tell you two things

1 get sprocket specialists sprockets cause they are the best out there

2 if you go for more up top your gonna lose some down low, so unless you plan on riding in your higher RPMs alot of the time, its not worth it :cheers

Yeah, sprocket specialists gave me some good sprockets a while back. I really don't want to run in the higher RPM's in the bottom end. I will most likely stick with the stock gearing for now, get my exhaust on and let her breath some. I think that's the problem that I think is going on, I feel like there isn't enough breathing room there. Thanks

sorry i think that i wrote that out wrong, what i meant was if your gonna cruise the streets with that type of gearing your gonna have to stay in higher RPMs to have any get up and go like it has now :cheers

You're gonna make your bike slower if you throw any smaller gears at it! It already doesnt have enough power to pull redline with the stock gearing.

If you go up one or two teeth in the back, you will be able to pull redline, and have a little more bottem end. You won't lose much topend this route. The lower gearing is better acclerating, and more rpm's is gonna = top end gain.

Personally, i think the bikes are geared rediculously high...probably for MPG claims by the manufacturer. I've got 520 chain and sprockets, and am running 15-49 (-1/+1) and with a recallibrated speedo, I top out between 150-160.......and that is still stupid fast! Alot of riding in those speeds will surely shorten you're life.


But, that's just my opinion.

I guess I am failing to see what it is you are trying to accomplish. I am not sure what you mean by "I think that's the problem that I think is going on, I feel like there isn't enough breathing room there"

Do you want more power in the lower RPM??? If this is the case, you bought the wrong bike. The R6 doesn't start making power until about 8-9k RPM. If you want it to feel like you have more power in the lower RPM, then you will want to LOWER the gearing. That will be adding teeth to the rear, or dropping in the front.

If you want the bike to be going faster for a given RPM, then you want your gearing taller. So add a tooth up front, or drop a few in back. I think this is a BAD idea on the R6 as you will be giving up some accelleration, and if you run the RPM too low... you will be lugging the engine down. Not a good thing on a low torque engine that is DESIGNED to rev high.

Stick with the stock gearing for a while. Once you are through your break-in, THEN see if you want to change the gearing. Once you get the revs over 8k, the R6 comes alive. Below that, the power is under-whelming.
