Hello All,

New user here. Active in other forum (mazdaspeedforums.org) for my 06 MS6. Also currently ride an 07 Ninja 650r for over 2 years now. Looking to upgrade to the R6, CBR, GSXR, ZX-6R level and have been doing my fair share of reading and researching of pros and cons. Also spent yesterday test riding quite a few.

This is not a question of "which is better", but more specific to the R6. I'm a casual rider, with occasional spirited rides through the mountains.

I've narrowed it down between the R6 and the CBR. I love the styling that the 2006+ R6 models have and am leaning that direction. The only thing I struggled with is the higher top-end. It felt like I had to give it a ton more revs to get going, and really didn't start pulling until much higher, which I confirmed in quite a few reviews online. Since I don't plan on tracking it this seemed like a disadvantage to the 07+ CBR lineup that I test rode which had a much more linear power delivery.

Question: I was talking to a friend who used to have a R6 and he geared down his front to improve his low-end. Just wanted to get a grasp of what others opinion on this might be: Does this only impact low-end and not the midrange? How much does it actually affect the odometer, if at all? General response to my analysis above?

Thanks in advance for any advice!

Think of it like shifting gears on a bicycle... the engine (your legs) have the same power but the different gearing allows you to get torque to the wheels better for a given speed. When you have it in a low gear, like when you go up hills, it makes pedaling easy but you can only spin your legs so fast and are limited on your top speed, more or less. The same is true for changing the gearing on the motorcycle. Your revs will spin up faster, getting you the more powerful part of the rev range sooner, but you will be limiting your top speed. If you're okay with limiting your top speed to 135-140 mph (depending on gearing) then its not such a big deal.

I went -1 in the front on my 2005 R6 and I like it. I might try -1 in front and +1 in back next time. Going -1 in front changes the speedo/mileage 9%. You can buy things that plug into your bike (speedo healer) that correct this, or for the 2006+ you can flash the ECU and correct for this. I already had 35k miles on my bike when I changed the front sprocket, so I didn't bother.

If you want mid range, why not a v-twin or triple? Or a liter bike?

if you're only riding street, you should save yourself some backache and go with a comfortable bike. if not a sport-touring bike, perhaps a gsxr 600 or zx-6r. they are both MUCH more comfortable for street riding than the r6. if you find you need more "low-end" you probably need to take it to a track...

gearingcommander.com it doesn't explain why but it'll show the effects of changing the gearing.
R6 is the least desired on the street, but it's personal preference. The r6 is fine for street tho, it does have a weak low end but it still takes off faster than most cars you'll see. I almost like having all the power exclusively up top. only in the power when you want it and not having to short shift to avoid holding onto a rocket.
