I have a 2023 ZX6R ABS with a LeoVince lv 10 slip on and stock air filter. I’m considering an ECU flash, aftermarket air filter, and eventually a full exhaust system.

For people who have done these mods on a 2019–2023 ZX-6R, was the difference actually noticeable on the street? I’m mainly interested in:
•throttle response and smoothness
•midrange/top-end power
• how much power you realistically gained
• whether a full system was worth the cost over just a slip on + flash
• reliability or drivability issues afterward

I’m planning to keep the bike for a while, so I’m more interested in a good long term setup than just making it louder. If you got a flash who flashed it? Im considering moore mafia

What is the real difference in reliability between these two motorcycles, especially in terms of the engine, and how long they last over time, and what is the risk of fatal breakdowns?

I just bought this bike and noticed this. Please swipe for more pics!

Help pls

Previous owner didn't ride the bike as much and didn't do any maintenance (he had it for 600 miles before I bought it off of him.) Should I bleed the brakes out at this point? Fluid's not dark but people have said to bleed it every 2 years.

I’m looking for an exhaust other than these bulky slip ons that are wrapped in that fake carbon fiber I personally think it looks tacky any recommendations are appreciated

Co worker sold me this zzr for 2500 good deal or nah ?

I didn't start out riding with a specific love of Kawasaki. They keep finding me.

First a Copart rebuild of a structural damage 2022 Z900RS and now I welcome a damaged and sorry looking 2025 Versys 1100S to the stable.

Zero intention, they just keep finding me at the right time when I need something to repair to distract me from the world.

Saturday was a blast!! Weather was amazing! Couldn’t think of a better way to spend the day!! For those that don’t know this is Summit Point Main.

i’m short and weak and refuse to use lowering links on my next bike so what does a girl do in the sitch? i’m not a speed demon by any means but would like something quicker than my r3. not ready to upgrade yet but hopefully at the end of next season.

what would you guys recommend? would a seat shave be enough to make a 636 work for me? or should i play it safe with the 4rr, slightly smaller bike with seat shave would probs work well for me. will i be satisfied with the 4rr? if i go for the 4rr i plan on doing full exhaust and ecu tune.
i know people say the 4rr is a waste because it also expensive for a 400. but im happy to spend on a bike if it is the right one for me and i’ll have fun with it for a while. i’m planning on this next bike to be a forever bike. no plans on upgrading after this if i can avoid it.

happy to hear everyone’s opinions.

edit: also adjusting the preload? should help me touch the ground no? thoughts? worth it?

edit: wow thank you all for the thoughtful replies!!!!!

FAQ:
i don’t wanna lower it because a bike is built with the stock suspension height for a reason!!!! i want my bike to ride the way the engineers designed it to.
i want a 4cyl. i just dooo, i can’t help it. high reving, exciting top end, and i like the sportiness of the 4rr over a 650. and i don’t necessarily need 600+ ccs which is why im super open to the 4rr over 636 as well.

edit:
also i just have a good feeling about the 4rr. i think i’ll have fun with it and be comfy on it. my bf has a 600 so if one day i rly desire a proper super sport i know he’d let me ride his and see if it’s right for me.
thank you for all the thoughts and opinions. i think when the time comes i’ll go for the 4rr unless something massively changes between now and then.

edit: does anyone know if kawasaki has plans to update the 4rr soon? the new 6r body looks amazing and i'd love that look on the 4rr.

edit: GAAAAH IDK i want a 636 mannnn. should i just lower that bitch? drop the suspension 1inch, do a seat shave like 1.25 inch? adjust the preload? and wear big boots and call it a day?

I have a 2021 kawasaki Teryx 4 800. Are the oem or more expensive belts worth it?

Hey guys,
I need some input. I bought this 08 Vulcan 900 Classic LT about a year ago. It’s got 8000 miles on it. And a couple of times after I have been riding and one time from the start, it felt like it was choking like it was just losing ability to breathe is what it feels like it doesn’t feel like it’s losing gas or not getting fuel to me. But when I would pull the clutch lever and rev, it would smoothly rev but in gear It would choke out and it would do that for a ride always when I tried to pour on the throttle, but it would allow me to maintain driving speed and the next ride it wouldn’t do it. But then today, whether I was disengaging the clutch or not, it was just choking to death. And it wouldn’t hold speed at all until I finally had to pull over and cranking the throttle on it It felt like it was either drowning in gas or like it’s not exhausting or getting intake but the air filters brand new and clean. And I recently changed the oil and inspected the oil screen, which is completely clean. Have any of you dealt with that before? Or have Any ideas what this might be? Thanks in advance for any and all input.

Tbh, I’m honestly so upset right now.

My ZX4R is basically my baby. I’ve had her for less than a year, and I’m still very much in that “park, turn around, and look at her one more time” phase.

I parked her in an underground garage and went to a yoga class. I was only gone for about half a day.

When I came back, my baby was lying on her side. Someone had knocked her over and just left.

And somehow, my helmet was gone too.

The parking spot itself isn’t covered by any cameras, so at first I thought there was basically no way I’d find out who did it.

Thankfully, my dash cam caught enough of the other vehicle for me to identify some of its features. I then checked the cameras at the garage exit, and luckily I could see the same vehicle leaving and get the license plate.

So at least I have something to give to the insurance company.

I’m still waiting on the damage assessment, but there’s a real possibility they might call her a total loss.

I’ve had this bike for less than a year. I literally just went to yoga for a few hours. Ugh.

I know motorcycles can get knocked over while parked, but coming back to find your bike like that is such a horrible feeling.

Anyway, just needed to vent a little. Hopefully the insurance side of this goes smoothly.

2025 Ninja 1100SX. Celebrating three weeks of ownership and already just below 1k miles.

Bike was cool. Me......

I'm looking at trading in my 22 Ninja 650 that's mostly stock, with over 24k miles on it to a dealership for 4k and pick up a 26 ZX4rr theyre selling with all fees for 10.5k. I think its not a bad deal, if anyone thinks I should street sell my 650 let me know. What I want to know is about the ECU upgrading, my fiance is getting into riding so I was hoping I could just buy a second ECU and swap them when I want to ride the bike tuned up and then when she rides it, tune it down. In my experience with working on cars, you can't just swap PCMs as they are integrated to the key system and log your mileage, i don't know if bikes work the exact same. Also some advice on who should tune my ECU

I've recently picked up an interest in taking photos on a cheaper Kodak photomatic camera, and the photos give an old vintage vibe. Took this one this morning in the driveway.
