Sprockets

I do mostly highway riding, but I was thinking of getting a sprocket kit. Anyone know if it will make a big difference in fuel economy if I drop one in the front and add one in the rear? If it doesn't make a big difference I would like more "get up and go".

Wow! you are fast, you were haulin' @$$ when I past you.

I dropped two in the front on my 2005 R6 and you will get more 'get up and go' / off-the-line take-off response. The drawback is that you lose top-end speed. I didn't care, plus the other mods I did to the bike, made up and over what I lost.

The issue that you will run into, though I forgot how it goes, is going down in the front and up in the rear, end up cancelling each other out. Someone on here will be able to tell you what the conversion is, like if you go 1 down in the front and (I think) 2 or 3 up in the rear, it cancels out. I forget, like I said.

You could search by threads started by me, since I know I started one about this topic. The answer will also be there.

Dude you just bought your CBR600RR, the best 600 supersport of 2007, and you're already talking about wheelies, stoppies, riding only on the highway, and getting a sprocket kit. This isn't that kind of forum, and that's not what that bike is made for. Chill out, buy and wear all your gear all the time, take the MSF if you haven't yet, do some reading, and practice riding with proper technique.

That being said, a sprocket kit like you are talking about will REDUCE your fuel economy because to go a given speed you will have to be at a higher RPM. People do the gearing mods you are talking about to increase acceleration, and they give up top speed in return. Also, people will do a more dramatic gearing change for stunt bikes, like 2 down in front and 6 up in the rear, or something like that, because it makes wheelies extremely easy. You would need to make the front gear larger and/or the back gear smaller to increase fuel economy, but that will also decrease your acceleration, although it would give you a higher top speed. Also note that changing your gearing will make your speedometer incorrect and you will have to buy a speedo healer.

Actually, you are thinking about -1 front being close to +2 in the rear. If you do them at the same time you get even more low end. They don't cancel each other

Fuel wise, you will get worse mileage because at -1 +2 your revs will be higher.

No, going down in the front and going up in the rear ADD together, not cancel out.

Well, I figured I wasn't correct, but I know it cancels somehow. Like if you go down in the front and down in the rear then? I don't recall.

However, I didn't do a speedo healer on mine. Just had a cop with a radar nail me with a radar gun, asked him what the speed was and subtract all the time. It's easy! But I did keep the original sprocket if I want to change it back.

I think mine is recommended 2 up in back and 1 down in front, from the stock gearing. read it somewhere. But no biggy to me I'm happy with it geared stock. Or i could have it completetly backwards. No need to regear mine i don't stunt or race so when i get new chain sprocket i always get stock gearing size. maybe one these days i'll get my lazy butt to a track day LOL.

Who needs tools i got zip ties & electrical tape

1 down is pretty darn good on the SV, it really brings it's accel up. You can get one for like $20, it's a cheap very good performance mod.

Easy easy, you don't have to be so critical. I'm new to sport bikes, I have alot of fun on mine safely. I don't mean to give the wrong impression, I do value my life. I'm just asking questions so when I'm ready I'll know what to do. Thank for advise though.

Wow! you are fast, you were haulin' @$$ when I past you.

I have the exact same bike and put it through it's paces. There is no reason a new rider needs to be fooling with the sprockets unless you are trying to make it into a wheelie machine or looking for the best ratio for the track.

BTW, reroute your overflow tubes or you will stain your left lower fairing.

I went -1 front +2 rear on mine and it changed the gearing quite a bit. At 80 I run about 7-8k now compared to 4-5k I dropped about 50 miles on a tank too. This was actually just doing the -1 front as I already had +2 in the rear.

i went down one on the front, im really happy with it, -1 +2 would have been too much, then again im on a liter bike so take that as you will.

No crap your bike is white it's in your avy, we have the same exact bike and color. If you look at the BOTM this month, you will see mine.

I ziptied mine pointing out, mine's stained already though. You just have to work with what slack you got and try to make those stupid tubes point away from the lower fairing. I have no pics of my bike from that side to show you. I take em from the other side to not show that stupid brown stain that won't come off.

Green is where it has stain (after this pic was taken), Red is where the tubes come out you can take off the fairing and try to zip tie going straight down, but I was afraid of getting fluid on my tires as I was riding, so I zip tied mine well out to the left of the fairing.

I don't want to push you in any direction but I do believe that the best tool when it comes to riding is doing your research here on the net! I found some good articles when I started riding a few years ago and I think they helped me more than anything else! Learning proper technique is more important than making mods to your bike. Especially your bike!!! Its a great bike stock and VERY capable!

http://www.sportrider.com/motorcycle...ide/index.html

Do me a favor and read every article here on this website as I have found most useful and there is so much info here it will take days to go through! There are plenty of tech articles too.

Hope you find it as interesting as I did.
