I would be in on the "group buy" or whatever, if, @Gravesport had more to disclose at this time, especially dyno numbers, or brake pad data to share.

I have respect for @Chuck Graves , I remember rooting for him when he rode a Team Hammer bike about 30 years ago?
I remember rooting for Grant and Josh back in the day, too.
I don't want to spend my money just because someone got preferential treatment with the ZX-4RR, and @Gravesport definitely has it.

FYI
We have 3 tunes developed at this time
Unrestricted
Unrestricted for the Graves Cat back system
Supersport for the Graves Full Ti system
All 3 tunes have incredible gains
Yes, I'd like to know what each of these three levels offers in the way of performance gains over the stock bike (which we don't even know yet ! :confused:)

What else was done for the the Supersport tune with the Graves Full ti system ? Airbox/velocity stack mods, etc.

Why can't we see the numbers?
Are you guys sworn to keeping it a secret until the bikes hit dealers?
If not, post it up.
I would like to see a stock pull vs each state of tune Graves will be offering.

I don’t think Kawasaki has released official HP numbers for the US market yet. So I’m sure there is an NDA.

Here's a candid shot from the race shop. The cat back exhaust looks really clean on the ZX-4RR.

Looking good !

Is that a ZX25R in the background ?

Also, a question since you guys have a bike actually there -
Do you know the physical difference between the stock seat and the Kawasaki accessory sport seat ?

Thanks ! 😉

The super sport tune is stock with the Graves Full Ti system only and pump gas or VP MGP

By that, do you mean it doesn't matter ?

Or does it mean the #1 option (unrestricted) can run on pump gas, but up to the 3rd option (Supersport with full ti), it can be optimized for the VP fuel ?
We did the mapping with VP MGP. This is a stable consistent fuel. Pump gas from just about anywhere in the country will work ok with this. There are similar fuels available from other companies that will work when or if the VP MGP is unavailable. The VP MGP is the Moto America spec fuel and if you are in another country and need something similar it is a match to the spec of most of the motorcycles road race organizations.
