Juki MO654DE Review In Detail

There is no question about the quality of Juki MO654DE. It is a champion performer. The stitch quality is excellent. However it misses out on a free arm.

Juki has some quality sergers and MO654DE is one among them. MO654DE is a 2/3/4 Thread serger. I will give a small introduction for those who are not quite aware of Juki as a brand. Juki is a Japanese company which makes high quality industrial sewing machines. They have been a global leader among industrial sewing machines for decades. 

Juki MO654DE comes with color coded threading system in which all the paths are well marked. This must make it very easy to thread. Tension adjustment can be easily done by turning the dial. 'Normal tensions' are highlighted for convenience. Super easy looper threading system is one unique feature of this machine. You can thread in a matter of seconds as the lower looper threader gets disengaged for threading. You just need to slide the thread into the slot and snap the looper into place.

Juki MO654DE comes with a multi-function presser foot which will allow you to create overlock stitches and add tape, elastic, ribbon, or sequins to your creations. It has snap-on presser feet for easy feet changing. The heavy duty knife system assures consistent and easy cutting for all kinds of fabrics. The built-in seam guide takes away any kind of guess work. You can easily adjust the cutting width by turning the dial, this will allow you to create perfect seams and rolled edges. The highlight of this serger is that automatic rolled hemming can be done quite easily with the flip of a switch. The differential feed adjustment system moves the fabric as you want it to be. Differential feed is adjustable in the ratio 0.7 : 2.0. Stitch length can be adjusted using the dial. There is an extra-high presser foot lifter which gives a maximum lift of 5mm.

Stitches available on MO654DE are

•    4-Thread Overlock
•    3-Thread Flatlock
•    3-Thread Narrow Overlock
•    3-Thread Overlock
•    3-Thread Rolled Hem
•    2-Thread Rolled Hem
•    2-Thread Overcast

This serger can sew at a speed of 1500 rpm. This is really fast compared to other sergers in the same segment.  It weighs around 15.5 lbs which is pretty light for a serger.

Ease of Use

Juki MO654DE is a quality serger, it has to be said. Even though MO654DE is lightweight, it is a stable machine, it never moves around when you are sewing at high speeds. Talking about speed, this serger can deliver 1500 stitches/min, which is really fast. You will experience this only when you compare it with 1300 stitches/min speed sergers of the same segment. This serger definitely has a powerful motor for high performance and at the same time it is quite good for going slow around the curves. This is something that really impressed me.

A serger provides professional finish to your projects and Juki MO654DE does the same. The stitches are of high quality. The performance on thick fabrics like denim is very impressive. The precise speed control and seam allowance markings make it easier for a beginner as well as a seasoned sewer. The machine comes threaded in the box. This serger has a wonderful knife, it cuts through almost all kinds fabric with ease. The 4 thread works quite well for swimwear like fabrics. 


There is no free arm.

No coverstitch option.
