CSC’s 2021 RX4 Colors

The new CSC RX4 is here, and they are moving out quickly from the CSC plant in Azusa, California.  CSC Motorcycles is offering two colors on the new RX4, as shown in the photo above Steve Seidner recently sent to me.  One is a vibrant yellow and the other is a deep, rich blue.  I like them.  If I had to pick one, I’d go with the yellow.  Yellow just seems to work on ADV bike.  There are a number of changes incorporated on the new RX4 motorcycles, as outlined in the CSC mailer below.  The big ones are the spoked tubeless wheels, the new TFT dash, and a tire pressure monitoring system.

We tested the RX4 extensively when it first came to America and published a comparison between it, the CSC RX3, and the Kawasasaki KLR 650.  You can see those reports here.  I may well have been the first American to ever ride an RX4 when I was in China visiting the Zongshen factory not that long ago.   I rode the prototype (literally a 450cc engine in an RX3), and on a subsequent visit, one of the early preproduction models.

Tooling around the Zongshen test track on a preproduction RX4…those were fun times.

I love traveling to China, and I particularly like visiting the Zongshen plant and Chongqing.  It’s a city most folks haven’t heard of here in the US, even though at 34 million inhabitants it is one of the largest cities on the planet.  With that, here’s the info from CSC Motorcycles:

The new 2021 CSC RX4 is the motorcycle ADV riders have been waiting for. Powerful. Economical. Modern.  The RX4 is an all-around versatile motorcycle that is perfect for real-world riding – including highway cruising, adventure touring, or simply commuting to work economically.

The 450cc single-cylinder, 4-valve, overhead cam, counter-balanced engine produces 40.2 horsepower and achieves a top speed over 95 miles per hour. The RX4 is water-cooled and equipped with Delphi fuel injection and electric start. The bike features a six-speed transmission.

The new RX4 includes an adjustable windscreen, comfortable touring seat and foot pegs with removable rubber inserts. The RX4 features an all digital TFT Display Gauges: dash with digital speedometer, tachometer, odometer, trip odometer, fuel gauge, gear indicator, neutral light, temperature gauge, clock, turn signal and high beam indicators, and Bluetooth connectivity for caller ID. Above the dash there are USB and 12-volt charging outlets included as standard equipment.

The new CSC RX4 includes a 300-watt alternator to power accessories with two prewired outlets under the seat.

The RX4 features LED turn signals and brake light plus LED day-time running lights. The headlamps are controlled by an automatic light sensor. The RX4 has a standard 5.3-gallon gas tank with locking cap. With fuel consumption exceeding 60 miles per gallon, the RX4 has an honest range approaching 300 miles.

The CSC RX4 is outfitted with spoked wheels, black anodized aluminum rims and 80/20 tubeless tires.

The RX4 comes standard with molded side cases, mounting racks and a TALL rear top box – which is large enough for a full-face helmet. Or RX4 owners can select the OPTIONAL package of Tourfella aluminum side cases and rear top box, all with custom side pannier and rear mounting racks.

The CSC RX4 is an unmatched value in the adventure motorcycle category. The powerful and economical 450cc motor is paired with a huge list of standard features that cannot be duplicated elsewhere.
