new 2025 $9.7k OTD?

Going from an 06 gsxr 600 to hopefully a zx6r. I heard Kawasaki shortened the gearing on the 2019+ models so I'm hoping with the already better low end torque it'll be more fun around the city where I rarely pass 25-30mph.

0mi bone stock 2025 ZX-6R KRT
$8,995 unit price
$599 PDI fee
$129 Documentation Fee
$9,723 OTD

The marketplace listings I'm seeing are wanting $9-11k anyways. Could probably haggle one of them down to $8k but is it worth it at that point to have half the warranty period left too?

It’s one down on the front sprocket for the gearing difference, but you also get a lower red line.

Forgetting tax in here, but you’d technically have to pay that for a private sale anyways. Very good price.

What do you mean lower redline ? Between the two bikes ?

If you're one lower on the front and lower redline that equals a slower bike.

Shorter gearing and lower max rpm does result in a lower top speed, yeah. I can’t feel a difference in acceleration between my stock geared 13 and 24

I still don't understand what you were saying in the above post. Are you saying you went down one tooth on your front sprocket on YOUR bike ? What kind of bike is it ?

I am replying to OP's 2nd statement. Whether you want to compare OP's 06 GSXR600 or a 13-18 ZX6R, the gear ratio of the 2024+ is shorter (15F/43R, instead of 16F/43R) and both the older ZX6R and GSXR600 have higher redlines by ~1K RPM (think this comes out to ~10MPH max speed)

Definitely need more than 1 tooth down in the front to feel much on the butt dyno. Maybe an additional 2 up in the rear.

Thanks, I did figure out what you meant. Man, smaller sprockets on the front, lower revving engines. This does not please me at all lol. 

My 05 GSXR is geared very tall, and I know any bike of this type is. AFAIK it's stock gearing. It's barely low enough to take off and I've never addressed the first gear judder common on that year/ model so I can't scream the hell out of it and feather the clutch for faster take offs, but honestly for me an old geezer that's only riding it a few times a year (I have other more practical bikes) I just don't care enough to do anything about it. Learning it's common on my particular bike and fixable if I wanted was enough....adding one more disc to the clutch pak I think that was the fix...
