【YSS】MONO LINE Rear Single Shock [MZ Series] MZ456 Review

Cheaper and better than OEM sus.

YSS Rear Suspension.
This product is MZ456, which is the least expensive model compared to MG and MU with a separate Tank.
We tend to focus on the presence or absence of Tank, attenuation, etc., but this product EmulsionType. It is also important to note that the part that is
EmulsionType refers to a structure without the membrane that is normally present between Gas and Oil. It seems to be a structure that cannot be turned sideways, which should not be a problem for normal use.
I think it may be affected by a fall, etc.... It should not be a problem for normal use...

For CBR650F there is a caveat.
First, the MZ456 that comes up when searching for CBR650F on webike is CBR650F But Late (Part No. 117-2511224). (Part No. 117-2511224)
(By the way, even in the later stage, the one for CB650F is 117-2511510, so it is different.)

117-2511210 is compatible with CBR650F first half. This product is common with CB650F first half.

As a side note, when I first purchased the MZ456, it was listed on the YSSJapan homepage as having a spring rate of 180 N/mm, but the product I received had a spring of 160 N/mm.
I checked and it was 160 on the YSSHomepage in Thailand, probably due to a model change (the model change for CBR650F changed the fitment a few years ago),
I think you copied and pasted the Spring rate as it was in the previous product.
I contacted YSSJapan about this misrepresentation and it has now been corrected.
I was lucky for myself because I was originally planning to wear a 150-160 Spring. I'm glad I didn't buy the pane...

Now, the installation.
Since it is a full cowl car, the removal of the cowl is a bit of a hassle, but once that is done, there is nothing special to be done.
If the jack is raised behind the center of gravity, except for the rear suspension, the rest can be easily removed by simply loosening the screws.
It has a ride height adjustment feature and was slightly shorter when opened compared to the OEM. it would be better to install it after the OEM standard.

After the replacement and sagging, I actually drove about 100 km.
The comparison is to OEM sus.

First, Spring rate 160N was just right to slightly firm for my 56 kg weight.
I was wondering if 150N would be acceptable if it was for one person only, but it seems acceptable. I might gain weight...

However, it is much better than the OEM suspension. That said, the OEM suspension is so hard that I have not felt Stroke at all (not that I haven't) since I bought the car new,
Still, I think the Damper kept it from stretching so it didn't repel.
Well, not only the 650F, but OEMSpring is often designed to be used by two people, so it is generally firmer...

Damper has only rebound damping and 30 levels.
I thought the weakest one moved a little too much, so I tightened it to 20 steps.
This is good because I don't run Circuit so I can just run normally.

It did not bottom out, nor did it run short on the extension side even with bumps, etc., so it is sufficient for our purposes for now.
I was originally dissatisfied with the OEM suspension and thought that the front suspension was too soft (damping was too weak on the rebound side) and the rear suspension was too firm, so I decided to replace the rear suspension.
Both front and rear finally feel like decent suspension.

Incidentally, the OEMRear suspension is about 100,000, so MU will cost you a ton, while MZ will cost you less.
The price is lower, the spring can be replaced, the damper can be repaired even if it dies, and the damping can be adjusted, albeit only on the extension side, etc. Frankly speaking, there is no reason to choose the OEM.

If I had to venture a guess, I would say that it is inexpensive, and although it is a bit shabby in terms of appearance, it is not that noticeable, so I think it is good enough. View detail

Better than new NORMAL

We decided to replace the Normal suspension because the shaking of the suspension was getting worse and we judged that it had reached the end of its useful life.
I decided to choose an Other Brand Product, and decided on YSS, which has a good reputation for its cost performance.
This Motorcycle suspension replacement is simply a matter of tightening the upper mounting bolt into the Screw hole on the Frame.
It can be done in a short time by simply removing the footpeg cover to remove the upper mounting bolt.
Since there are no instructions for installation orientation, I installed it with the ROD facing down, the engraving and Sticker visible from the outside.

I rode with the manufacturer's factory settings except for the suspension length, and it was firm when I stepped on it while absorbing the impact.
I think it is a good suspension that holds up well. I would like to find the right setting for my riding style by adjusting it from now on.

The delivery time at the time of ordering was around 6 days, but after ordering, I received an e-mail saying that the delivery time would be 3.5 months and delivery would be in July or August, which was a bit of a surprise,
I thought to myself, "It's not possible to keep up-to-date delivery dates for a large number of items, so I'll just wait patiently. Thank you Webig and YSS for your hard work. View detail

The stiffness, firmness, and suppleness of the new car have been restored.

The stiffness, firmness, and suppleness of the new car have been restored.
This is an over-marketed TDM900.

The motorcycle is used for touring (9) and running errands (1), and for touring, it is used for driving on mountain roads, ranging from a comfortable ride to a more aggressive ride with a safety margin.

Before the conversion, there was a feeling of discomfort and near-misses due to poor “splash” and settling before the corner and in the downhill deceleration zone, as well as a large vertical movement in the corner caused by the undulation of the road surface.
After the conversion, the large capacity was improved and it became easier to ride.

It is easier to ride and more secure, and the averaging speed of Touring has increased.

Setting is working Shop to intermediate/standard for now. The improvement effect by the conversion is clear and I am not dissatisfied with it, so I will leave it as it is for the time being.

The price was less expensive and helpful compared to other OEM companies' products and OEM sus, although they are no longer sold.
Spring is red, and I like it because it matches the color of the RedBlack car body. View detail

Performance in Touring is satisfactory

It is a suspension that moves smoothly, and the spring rate is lower than that of NORMAL. It is very smooth and comfortable to ride in the early stage, but it also holds its ground well after sinking down.
I would like to try to adjust it by attacking a mountain pass or loading two cans, but the problem is the pre-road adjustment, which is a maintenance problem of this vehicle (Yamaha 2GH). I wonder if there is enough space to move the adjustment tool. View detail

Expensive, but good

The Instruction Manual said to overhaul it after 10,000 km, but I asked the manufacturer directly because there was nothing wrong with it visually. I asked the manufacturer directly. I thought it would be good if I could run about 30,000 km. The ride quality is better than OEM. The springs are thicker and stiffer than the OEM ones. I thought they were good and I would like to change the Fork Spring to yes. View detail
