[Toxic-Male-ZX6R]

Hey all,

I'm Az from NW UK and it's great to be hear alongside fellow like minded people. Was riding in the early 2000's for a number of years, first bike was a Ninja ZX6R J2 in blue, loved it. Got married, kids etc and stopped riding...

Roll round 2022, a number of years later going through divorce and child arrangement order and finally no wife to stop me getting back on a bike

Got myself a 2019 ZX6R GKF 636 and loving it. Starting to pimp it out with current mods being, TST Industries intergrated tail light, illegal show plate on the back, TST Industries elite fender eliminator, Scorpion Red Power carbon Serkat taper slip on and bypass pipe. Ready for decat next week and then a dyno tune to get every drop of power out of it.

Looking forward to seeing you on the forums 👍

Oh, by the way my username is what I'm supposed to be in other people's eyes 🤣 I guess you can figure that one out 😉

Awesome bike, welcome friend! I have the same year only it is in gray. I will say this, they are incredibly fun! One thing though, your catalytic converter is actually inside of your exhaust headers. So, you could punch it out or swap your header all together. But the metal box in front of your rear tire is actually just a pre-muffler. It is a great way to reduce weight though if you end up removing it!

I have done similar things to mine, as you have yours.

They sure are amazing machines! You have a nice setup there👍🏼 That rear tyre looks huge, what size are you running?

How does yours feel after the decat and flash? Was there a noticeable improvement in perfomance across the rev range? Do you also feel alot of heat without the heat shield on the pipe?

I've already removed the pre muffler on mine and replaced it with a by-pass pipe from Scorpion, however they don't seem to produce a header for it which is strange 🤔

A local motorcycle exhaust specialist (Max Torque Cans) has had a look at the setup on mine and he can cut out the cat and replace it with a pipe linking in to the slip on. Can't wait to get it done on Thursday 😊

I think I'll complete my upgrades with the Evotech exhaust hanger, crash bungs, levers and bar ends and with the TST LED front indicator lights 😊

When my bike was stock, it was pretty stale feeling up top, in the high RPM’s. After I swapped to a full system, and had the ECU flash done. The difference was day and night. The bike power wheelies in 1st gear now, not snatching it, or slingshotting it up either. Top rpm range is much stronger.

My rear tire is a 180/60/17. Not exactly the correct size, but it’s a tire.


Graves full system quotes 13hp gains up top, and 11hp gains in the mid range with their full system. But I’ve never dyno’d my bike before and after. So, I have no idea how much power it makes. If I had to guess I’d say maybe 123whp-125whp. But I have no idea 🤷‍♂️

A lot of guys on this forum are legit track guys who can actually drive, so they feel like most HP modifications are a waste of time and money. Because being fast on a track comes down to driver skill. I totally understand this thinking, but I don’t really have any race tracks near me. So, my bike is just a street toy that pulls hard as hell Lol.

Got to say with the larger tyre you have it gives the bike more of a wider presence, and looks insane. I'm going to have that as option for mine once I replace the rubber 👍🏼

I can imagine the extra power and wheelies in 1st gear as you accelerate.. I used to have a R6 that did the same and it sure was fun. Hopefully after I get mine on a dyno I'm hopeing to achieve a stronger and smother pull through all the gears.

Yep, being a fast street toy sure is the aim after all the mods 😂 and definitely going to be looking to get it on track whenever I can. Not to thrash it about but more to understand its power and limits for better rideability.

This Njnja is going to be a keeper for many years for me therfore I want it at its best and for me to use it to much of my abilities as possible.

The big back tire does look freaking awesome lol. it’s only a little larger than the original though 180/55/17. I only grabbed it because I was curious and I also got a great deal on the Metzeler set. I started changing/balancing my own tires now though, so it’s easy enough to swap back to the original size and try other options as well.

 

[Toxic-Male-ZX6R]

That's pretty cool you can do that. Did you notice any difference with the wider tyre??

The 180/60/17 has a very aggressive profile and is mostly taller, and it does have a slightly larger contact patch touching the road at all times. From what I’ve read more throttle can be applied on a more aggressive lean angle while maintaining grip with the 180/60. I have not driven enough to have a solid opinion yet though. I’ve only put a couple miles on the tire so far, it has been pouring raining pretty hard here for the past few days since I‘ve just installed it. I will say this, the bike tips in easier. Leaning feels as if your falling right on over with little effort needed on turns. However, my opinion is a little skewed because my S22 was toast and squared off after 4,400 miles on it. Bridgestone sales the S22 factory tires in 180/60/17 as well. The 180/60/17 will alter your gearing some by making it taller more mph. But, the 2019+ ZX6R has such short and aggressive gearing I don’t think a change would really be necessary at all for gearing. The 180/55/17 is already one of the best tire sizes available. Especially in the S22. Your tires are excellent, mine were just bald/squared and needed replacing is all.

Wow, I'm surprised to hear your S22 had so much wear after only covering 4,400 miles on it. I'm definitely open to the idea of going for the 180/60 when I do eventually replace mine. Just hoping to get more than 4,400 miles as they are pretty new lol.

I guess it makes sense with the 180/60 having a larger area of contact on the road and providing more grip, and being easier to lean and on the turns. Thanks for the input 👍🏼 I think it can only improve the riding experience on what already is a pretty serious machine and the bonus is, it's gonna look more of a beast as yours already does.

I covered over 100 miles on mine today as soon as the sun came out and the roads had dried up.
Damm I enjoyed every second of it through the country roads. I do get the traction light coming on here and there when I pull hard through the gears and thats with it on the highest setting. Wondering if the 180/60 will make this happen less often.

Man, I thought getting 4,389 exact miles was amazing life span! I am coming from a 2007 Suzuki GSX-R1000 as my last bike, and I went through tires every 1,000-2,000 miles depending on the tire, some tires went as fast as 800-900 miles lol. so when I saw 4,500 miles on the rear S22 tire I felt blessed. Honestly, the factory pressure of 42 psi rear, and 36 psi front for the S22’s will provide the longest life span with the least grip available. I did have mine slightly less PSI than that, but not by much as I wanted longevity too. I have seen people squeeze out 5,000+ miles on a rear S22 but it was in bad shape with wires showing. I did cut mine open to see how much rubber was left after I removed it, and it was not much rubber left at all, maybe like 1mm thick of rubber and then it’s all inner core/wires/etc. I’ll say this, when I was at about 4,000+miles with the S22 on long trips down the highway the rear tire would get so hot, it would begin to melt. I felt like I was riding on a balloon sometimes the rubber was so thin.

Also, the the front will need to be replaced around the same mileage, if not sooner than that really..Not because it is bald, but it’ll be cupped like crazy. Cupping tires is not a bad thing, that’s just how front tires are on motorcycles. It’s from the tire gripping and twisting on the road for thousands of miles It just begins to deform in shape and fold at the tread grooves and it’ll look like a Lego after a while. It’ll still ride perfectly smooth, but it won’t look very safe is all. The only front tire that won’t cup easily is a slick tire as far as I know.


Anyways, 4,400 miles is really good life. That’s like 7,100 kilometers. You won’t find much better life than that without slightly compromising on tire grip. And if you need more grip as it is, I’d lower your PSI some.

Wow you been chewing through the rubber, you must be riding quite hard to go through them that quick.

I was hoping to get just under 6,000 on mine at the recommended pressure and that is with fast road riding. When I replace I'll be doing both of them and was thinking about going with the Pirelli Diablo which I've had in the past. To say that I read the reviews on the Metzeler which you have and they sound pretty good.

How much we taking in lowering the psi for more grip, a couple of psi per tyre??

I've currently done just over 2,000 on my current set so let's see how it goes.

These Racetec RR K1’s might last (3,000 miles) I’m still trying to dial in pressures. I’m at like 28 psi rear, and 31 psi front. And it literally feels like god like level grip. So much grip you can actually feel the front tire grabbing and sticking in corners. I also notice zero hopping on the rear tire under hard acceleration on bumpy roads. It’s like riding on a big grippy doughnut.

Some great tires that literally just came out are the new Pirelli Rosso IV Corsa’s. The Rosso IV’s were already newly released, but now they just optimized them even further with slightly stiffer side wall and they are Rosso IV Corsa. I ran Rosso IV’s on my GSXR1000, I think they are super competitive with the S22 with just a tad more grip and slightly less longevity than an S22 offers.

You’ll be hard pressed not to just install another set of S22’s again when the time comes though.

Enjoy your bike, ride safe. And maybe go get an ECU reflash done if you already have not done that.

28 psi!! Didn't know you can go so low. I guess with the wider rear tyre it's working.

I've juts dropped mine off for the decat and as I type they have called to say it is ready... Can't wait to go and collect it.

Next step is get it on the dyno 😊

 

[PhotoAl]

Oh yes, if you are looking for better grip the manufactures recommended pressures are too high. Don't recall when but a number of years ago everyone went the 36F 42R as a standard. I used to run much lower pressures with my FZ6, CBR and ZX6R.

On my sport touring bikes I've run closer to the 36/42 PSI pressures. That is mostly for better tire wear when doing a long haul with lots of interstate travel. Thinking about my next trip now. Leave in a couple of weeks and will go visit my sister in Michigan. From there will either go to the UP and then west or west on the ferry over to Wisconsin but wind up in ND and then Canada and ride across the plains to the Canadian Rockies. Then drop south and head back home. Maybe 3 weeks and 6,000 to 7,000 miles. I run Michelin Road 6s and for sure they will be flat in the center when I return even running at 42 in the rear. On the ride out the Tracer 900GT is nice but when I get to mountain I find myself wondering if there is a good way to load my gear on a ZX6R but then not he ride back I realize have to have something of a compromise since I'm not young nay more.

Hi all, new here too.
Just got to reply to this though, your insurance will be toast in the UK if you change tyre size. Other stuff like pipes and paint are just wriggle room for them to duck a claim but if you swap tyre size they will take a very dim view as your bike will be un-MOT-able. Its also a crap idea, Mr Kawasaki spent a lot of time and effort making the bike work with the standard rubber size... a taller ass will screw your rake angle (not surprised the bike tips in easily), it will be twitchy as a nun in a brothel at speed!

Hi Poacher

Welcome! I'm kind of sorted for insurance. I have a motor trade policy for my business with personal use on it and it also covers bikes any cc 😊 That saved me having to take out a separate policy just for the bike, happy days

Hi, my point was that if you had a woopsie and the insurance assessor looks at your bike and spots an incorrect fitment of tyre your insurance will be invalid... void... not worth a carrot... toast... In short, its a terrible idea!

Other than that, love the bike! It looks the nuts as it is
