I love Kawasaki, I've owned the ZX9r, ZX12r and the Z1000 (2005). In this case I'd take the RS660. It is such a wonderful looking piece of kit plus 100bhp is about right.

[@eirikaustad7580]

I agree, and I really love the ZX-4RR. The price would be fine if it had better suspension in the front, and a ZX-6R style frame, but it doesn't unfortunately. However I'd only buy a Aprilia with a valid warranty, so that if it breaks even after me taking care of it, the shop has to fix it, and not my stupid ass.

Awesome video! More ZX-4RR content! We still haven't seen a decent test drive of the ZX-4RR after the ECU flash other than that highway pull. Please make that video!

[@starztrukk]

The RS 660 is actually my first bike. Purchased last year for my 25th bday. Took two MSF courses, one before buying and another with the RS. Bone stock. This bike is only as aggressive as you are. I've been keeping it easy as I learn - it's so fun to grow with the RS because there's no ceiling. Its power demands respect, this is an Italian machine after all. But every time I ride, it's always smiles. Flat power band means I usually don't have to drop a gear if I don't feel like it, bike stays ready. And so light - you can throw this thing all in a highway lane. At 2650 miles, I've already dealt with both an oil leak and a coolant leak (coolant leak required gaskets to be replaced under warranty). Keep an eye on those fluid levels and you should be fine. Looking forward to many more miles of good times. Edit: Casey's RS looks and sounds incredible. 🤩

[@killswitch8653]

I also got the rs660 as my first bike at 25 and I agree, I’ve been riding for 4 months and haven’t even dropped it yet and I’ve only come close to getting into accidents when I get carried away in my ability to take corners. As long as you treat it with respect and stay level headed it’s not a bike that will easily kill you over a slight mistake anymore than a 400 imo. And all the technology it has truly helps when learning and having confidence. The dash is very informative vs the typical dash you see on other bikes in the low to mid range. The bike goes when you want to and it’s steady when you don’t

[@joshayers8522]

@starztrukk Awesome Very descriptive in the areas allot of us are looking at When not what you want to hear but what you need to hear turns into your truth then you have sold someone and I'm sold.. thanks man

[@illmaticeric]

I couldn't agree more. I bought the extrema as my first bike. Everything you said is spot on-throttle control, respect for the bike and power, and checking my ego. The bike is a beast. With the aids, I learned a lot and realized it is forgiving and might have had a different experience on a lesser bike. I could ride this machine all day! Cheers!

[@chrisdavies4323]

First "Bike" was a Vespa 50 ET2 in 1996, not ridden since. I'm now 40 fat and half bald. RS660 is amazing as a first bike if you're mature (scared of getting hurt) enough. Paid £9k new for mine in October and just done the run in service. Now desperately awaiting global warming so I can ride the dam thing, great video from across the pond

[@ultimatemassive9501]

ZX4 vs the similarly priced Street Triple R would be fun too.

[@BooStairs]

issue is that those are entirely different bikes. naked bike vs supersport

[@ultimatemassive9501]

@BooStairs Their ergonomics are as sporty as the ZX4, if not more. The only difference is that they lack fairings.

[@dhowting]

As cool as the ZX4-RR is my pick is still the 660....loved it when it was teased, announced, released and today. It's beautiful, has the tech package and the sound is mean and beefy. I'm also with you on the Acid Green being the BEST colour!! I'd swap the seat out for a red one though, don't know what they were thinking giving it two red wheels and a BLACK SEAT??!!??

Yammie Noob - I like your content.... I hate the fact that I am on Europe and I cannot participate in the Giveaways.... Love your content! keep it up :)

[@YYTRiD]

I agree with just about everything said about the 660, I was looking for more of a commuter bike and the one big complaint I had about the 660 was on long stretches of highway I felt like I got blown around quite a bit. I ended up going with a Ducati SS 939, little longer wheelbase, a little more power. if you aren't looking for a commuter (I ride 45mins for work) then rs660 is really hard to beat.

[@2a-usa476]

I use my RS660 every day 50 minutes each way to work and have done 4 hour highway stretches on it and I never felt like it needed more power or like I was getting blown around, it's so much fun...then again mine is very modded and tuned

[@BenefitMe1000]

Lol I wish I had known more about the RS660 and what it had to offer before I just decided to hop on a R6. Would’ve been inclined to spend more time on this bike refining my skills before hopping on a dedicated supersport where I was just trying to survive the ride the entire time. 😂😂😂 Nice video Yammie. That thing is a beaut.

[@joseph9556]

I think a "gooder" comparison is a zx4rr vs cbr650r. Both 4cyl, close price point and riding position. 400cc supersport vs 650cc sport

[@F_M.Vlogs.]

Now that Aprilia has released the rs457 I wonder where the review on that will be made? And what are your thoughts on the rs457 being a beginner bike?

[@oxthemidget]

Is there a list of the mods/parts from the RS in the video?

[@jvillain9946]

Im stuck between getting a zx600r and an rs660. The 2024 zx looks great especially with the new tft dash and it has that inline 4, but I feel the aprilia will be more usable. They both come with basically all the same additions and have the same quality for just about the same price. If they ever updated the cbr600rr Id get that bc I think it looks so much more raw, like it wants to rip. The cbr and zx insurance is like 3 times more expensive than the rs though.

[@lordplaza]

[@JBGUNS1]

Would the Zx6r be a closer comparison video to the rs660 ?

so how would you, or anyone else in the comments, compare or what would you recommend between the RS660 and a zx6r. Those are the two i'm torn between, I like the looks of the new zx6r more, but the rs660 seems to have more street friendly appeal. I love the power on the zx6r, but I don't see myself tracking a bike anytime soon. Is there one thats clearly more comfortable, or should be more comfortable? Mind y'all, i haven't been riding sport bikes yet but i BADLY want one, i've been riding big cruisers for a few years. Right now it's just between zx6r and rs660. Been leaning zx6r though.

[@Fenmore50]

RS660 hands down. I have both. The zx6r is borderline unbearable on the street. On the track it’s much closer but I think Aprilia still gets the nod for better electronics and lighter weight.

[@flip_moto]

I cross shopped/tested the zx6r, gsx750 and rs660. went with the RS and put clip-ons in it. happy with the decision just on the looks and having a ninja is sorta cliche. However, on track, I curse every time a gsxr750 pulls on me at the end of straight. no problem keeping up or passing any 600s, but damn that cheater 750 bike. Recently rode a Duc V2, and sticking with the RS.

If you want power obviously ZX4RR isnt the Best choice However one is very unique and the other is another ~600cc twin. I guess it comes to a question if you had 600 already or not - you wont feel like missing out anymore

[@brianbelcher7279]

With respect to your opinion--- One gives you plenty of power to grow into and the other gives you just enough power to grow out of. One gives you the best styling in class (subjective), the other just looks exactly like a zx6 or ninja 400. One gives you cruise control and the best electronics in class, the other gives you decent electronics for the price point. I think 100 hp is the most powerful 600 twin on the market today by quite a margin. And i'd rather have "just another 600 twin" than a 400cc inline 4 that ever so slowly pulls to 70 hp while deafeningly screaming way over 10,000 rpm just because "oh, what a novelty!" It does sound good if that's important to you. But so does a zx6 for hardly more money. If you REALLY want zx6 sound, but you are a bit precautious of 120 hp, then i guess i could see why you would get a zx4. The rs660 certainly SOUNDS like just another 600 twin while the zx4 is the best sounding 400
