My birthady was the 25th! I just picked up some tools from your site for my Ninja 400, how cool would it be to win the ZX4RR!!!

[@SacredCowStockyards]

I feel like this is the new gold standard for sportbikes. It's nuts, and it revs to the stratosphere, like a superbike. It's 400cc, so it's not enough power (and just as importantly, not enough TORQUE) to get away from you. It's exactly the right amount of power not just for a beginner but for just about any street bike. I honestly feel like this would be a forever bike.

[@aaronferguson9328]

yea i own a r6, and a 600rr and i literally cant use them at all, the rr is fun mid range but the r6 is going jail speed before i can use it, about to be trading in for this thing

Great video. I didn’t think it would sound so amazing without the muffler. The ZX-4RR reminds me of my first bike, a 1995 ZX-6…. I miss the sound and crazy power curve ever since I got rid of it. That’s why I put a deposit on one.

[@pranavhb1716]

The fact that it can gain near 50% more power after the dyno tune and a free flow exhaust is absolutely nuts

[@tw1st3d35]

You also gotta remove the 3-way catalytic converter and a full system straight pipe exhaust.

[@enderzebak2863]

thats because it is the intended horsepower lol

it always feels good to ride a slow bike fast because your using all the gears, pushing the bike to its limit and overall just safer cuz it isn't as deadly as going down the street ripping 180+ mph

[@SinOjOs-Transport]

Removing the muffler sounds kinda like the old Kerkers we used to run on the CB's & K1's back in the 70's & 80's. The megaphone was wa about 6 inches. The baffle reduced the exit to sbout 4 inches. 3 choices. 1. High Rpm short in lenth baffle. 2. Mid Range Rpm mid lenth baffle. 3. Low Rpm Long baffle. The more back pressure the better rpm torque & hp at low rpm. The mid provided, well, dont be surprised, best mid range power. The high, upper rpm gain. The difference was only in length. Not in circumference. Not a lot of sound difference. But was enough difference that power in the varios rpm region's was noticipal. Taking the muffler off the 400 rr. Simply made it sound more like before catalytic converters. With all the curves, catalytic convertes etc. I bet it produces more back pressure than the old kerkers i ran. As they were straight shots out after the initial down turn from the head. Looks to me. If you want to keep, or need to keep the original due to emissions or preference. No need in spending a lot of money to have a name on the pipe. I have noticed. None of the new pipes. Allow selecting baffling that can modify low, mid or high rpm output. Looks like the cheapest solution is simply remove muffler. Loud Bikes Saves Lives! If sound is an issue. Simply get a Super Trap end piece. You can add or decrease plates for the sound or high, mid, low torque. $50-$80. What the big new name brands charge. For simple slip on's. With no choice of tunability. Is a criminal act. WTF happened to building your own. Or modifying something off the shelf. Kiddies nowadays seem unskilled & lack in self produced invocation. Better to be the out crowd, self sufficient. Rather than the in crowd who is dependent upon others. But thinks it's cool because they spent a small fortune on a name. That does not allow them to control sound and or hp & torque at the rpm range they prefer to have a boost at.

[@gavinlee9478]

It sounds so good hopefully I can get my ZX6R to sound like this when I get it

[@gavinlee9478]

A little bit deeper tone though

[@BlatGirl-v8p]

I got the ZX25RR not too long ago. Traded my Ninja650 for it. Power band obviously totally different but ZX25RR is much more fun to ride and 650 was only technically a few more horses but heavier too! ZX25RR is 51bhp of fun! So sad they detuned the ZX4R for the states though. Basically, they are giving you a ZX25RR (which they didn’t bring into the country) for ZX4R money! Cheeky!

[@tysky9152]

My good sir. You just passed my grandma and she actually used you as an example of why I shouldn’t get a motorcycle. You think I’m joking, but you actually just passed her neighborhood.

Yeah a few years ago I was on my zx6r with Austin Racing exhaust in a residential area, just slowed down for some railroad tracks and gave it a little gas again to get back to speed limit at least. This old lady sitting outside motioned with her hands for me to slow it down. I just waved at her 😆 I wasn’t even going that fast but it kinda sounded like I was accelerating hard for a second. On my current GSXR 1000 R, that likely wouldn’t have happened.
