I agree, especially now that the bike is actually shipping out to owners.

The Z400 is a nice bike. I would be happy to have one. However, when you add the dealer jerk off fee of $1000 (that CSC does not have) it ends up being the same price.
OK for the same price I can have a name brand Kawasaki or Chinese. I get it. Even if the price is equal, the bikes are not.
For the same price CSC RX4 has a bigger gas tank for almost 100 miles more range.
A big wind shield. A tiny $75 option is available for the Kawasaki. The CSC has a 300 watt alternator for your accessories. The CSC RX4 has a better warranty. The RX4 comes with the engine crash guards. The RX4 has options for luggage. Most importantly, the CSC has a 19 inch front wheel.
If you like the stuff I listed get the CSC. If you like the brand Kawasaki get it for the same out the door price. Both are good choices for different reasons.

I would suggest simply renaming this forum to include both. We have little traffic as it is, and the bikes have so much in common.

Apples and oranges, isn't it? The Z400 is purely street, isn't it? Now if they had a Versys 400....

When I purchased my Z400 I received a U.S. Army veteran discount and a Rebate from Kawasaki, No “jerk off fee”! So my sales price for the Z was cheaper than the RX4, (Mr. Math, you’d better do the Math!), plus the twin cylinder is a lot smoother running than the single piston, unless you like vibrations.

Good Luck.

1cylinder it looks like you choose the bike that meets your needs and got a good price. Enjoy it and thank you for your service.

I found and read the published rider’s review of the RX4 motorcycle that was posted on the CSC home page. One item was very timely and important. They stated that an online library of tutorials showing how to maintain & service the RX4. I searched the CSC site but could not find tutorials dealing with the RX4. I really utilized these tutorials when I owned an RX3.
The second article stated the RX4 engine was a bit unrefined, and the throttle causes the engine’s rpms to speed and slow down unless the throttle is in the wide open position. There is occasional lurching when the throttle isn’t WOT! I had this similar problem when I first purchased an RX3 model years ago.
I’M HOPING THAT CSC, OR ZONGSHEN, CORRECTS THIS FUEL INJECTION PROBLEM BEFORE I PURCHASE AN RX4.
I’ll be waiting to hear that this lurching has been eliminated.

Certainly looks interesting.

1cylinder I have spent more time finally riding my RX4. As far as any lurching or surging, it is the same as my RX3. They both idle around 1600 rpm. Give it any throttle at all and you are at 3000 rpm. There seems to be nothing in between. With the power and gearing of the RX3, you really do not feel it surge. With the increased power of the RX4, you can feel this jump from 1600 to 3000 rpm more. After 3000 it is smooth as butter.

pyoungbl · 10-07-2019, 08:46 PM

I have ridden the Z400 a few times and really enjoyed its zip and general flickability. It's a fantastic little bike. With that said, it's not something I would want to take on any kind of a trip. The Z400 is strictly a street bike for short hops, one you really need to spin up to get it going. Once you have that engine spinning it's an absolute rocket...for 400cc. The RX4, in contrast, is a thumper. A 450cc single should have more torque at lower rpm and thus better for anything approaching off road. The basic designs are so different I cannot see any reason to compare them other than that the displacements are similar. It's like comparing a Lotus Evora 400 to a Jeep Wrangler...similar displacement but totally different design. I'd love to have both bikes (and cars) but that ain't gonna happen in this lifetime.

The Versus 300 has pretty much the same MSRP as the RX4. Your friendly Kawasaki dealer may really tack on a lot of extra costs, depending on where you live. I'm just more of a thumper fan.

1cylinderwonder · 10-08-2019, 11:15 AM

My Z400 has more horsepower, acceleration and weighs less than a RX4.
1. RX4—40.2 Hp, weighs 450 lbs, 27.3 torque.
2. Z400-46.6 Hp, weighs 362 lbs, 26.5 torque. It also goes 0-60 in 4.82 seconds, and the quarter mile in 14.02 seconds. And the engine has less vibrations. RPM @ 65mph: 6,500.

It feels like a thumper just a little at idle. By the time I get to freeway speeds, it really smooths out. Should be great for extended touring.

I finally added some luggage. It is really high quality water proof Pelican type cases not really meant for motorcycle. Works great.

Math Teacher · 10-11-2019, 01:06 PM

Here is a photo of the luggage I adapted to fit the RX4. I had CSC add the racks for the TourFella luggage, but not the cases. When these racks are added, the factory passenger grab bars are removed FYI.

Other things I noticed. The factory headlight is great. Even though the speedo and display looks the same as the RX3, the small lights for neutral and the turn indicator arrows are much brighter. I wonder if 2020 RX3 is also improved?

It seems easier to find neutral and the clutch lever has a nice smooth and gentle feel. It is like the Zong heard all of our nit picks about the RX3 and make them all better and more refined. Too many to list here.
