Fork Upgrade Kit

Fits: SUZUKI GSX-R150

5/5

We hope that GSX-R125User on the Circuit will find it useful!

It is supposed to be for GSX-R150, but I bought it for GSX-R125 because the distributor's website said it was for both 150 and 125. As a result, I was able to install it without any problem.
I also purchased this product as a Circuit Running and am satisfied with its perfect performance.
The installation process is a piece of cake if you have ever done a Fork oil change. Even if you have never done it before, you can do it if you have some tools. We recommend that you change the fork oil while doing the work.
The top cap of the fork is not screwed on like the FOR JAPAN MODEL production type, but only stopped by a C-ring using the force of the fork spring, so it requires a bit of hang, but as shown in the photo, it can be removed quite easily by using a Tie Down Belt and TWrench, etc. However, it can be easily detached by using a Tie Down Belt and TWrench as shown in the photo, or by preparing a 3-way Vise.
The Instruction Manual for the product is very unfriendly, but it seems to recommend an OilLevel of 125mm, so you will need about 200cc or less of Fork oil on the One Side when replacing. Also, although Fork Oil No. 30 is included in the package, it is not recommended to use Fork Oil No. 30. Use this with a Single Body. I don't think that's the case (it's only 250cc so it will run out after only One Side). I think the OEM No. 10 has enough viscosity, so you can mix No. 30 to your liking. View detail

MONO LINE Rear Single Shock [MZ Series] MZ366

Fits: YAMAHA SEROW225

5/5

I had my doubts, but I was right to buy it.

[How is it used?
The OEMRear shock on the SEROW225 initially caused Oil seepage. OEMOverhaul." To
I was thinking about it, but since Overhaul was quite expensive, I decided to install the YSS suspension that I was interested in anyway.
Was the one you received as per Image?
The actual product looks cool in the picture. My concern was whether it would interfere with the Frame, which is often mentioned, and whether it could be used for mountain play.
How was your experience with it?
Compared to the OEM, the YSS was the same length as the factory. I installed it on my car body as it was from the factory and there was no interference with the Frame on my WE.
Rear suspension was initially felt to be too hard, so I set it softer with 15 levels of damping in the middle, and also loosened the spring pre-road setting to make it softer.
The Stroke is the same as the OEM suspension, and with some adjustment, it should be able to do exactly what I want.
[Points to note]
During removal and installation, work with care as they are easily scratched as they are removed and attached in a light ring of wisdom.
How did it compare to other products?
Although we can't compare it to the OEM suspension, which was screwed up, the traction is firm. We have a wider range of adjustment.
It makes it fun. I was thinking OEMOverhaul if I didn't have an external suspension, but it was the right decision.

Front Fork Spring

3/5

It's not that bad from what I've tried.

However, the result was not so good as the objective of "Spring reinforcement to increase the braking power in the early stage of Brake".

The wire diameter of OEMSpring is 5mm. This Spring also had the same wire diameter of 5mm.
At this point, I thought, oh no.
Well, the density of the coil is higher than OEM's and the spring length is shorter, so we proceeded without thinking too much about it,
After assembling, I pushed it with my hand and found that the OEM one is somewhat harder.
I can't say for sure because I didn't measure the sag of OEMSpring, but OEMSpring seems to be 8.0 or 8.5 N/mm.
By the way, the sag after adding yssSpring is 17mm from the top of the Dust cover. (75 kg) The oil is Kawasaki G10 with an oil level of 100.
I am incorporating PD Valve, so I may not be able to rely on it too much.

I thought this might have been a hiccup, but I put it together and ran a test run, and it felt rather good.
Double column effect gives the feeling of pushing the Tire firmly at the back of the Brake and (OEM will inevitably have a stronger Air Spring effect when the Travel of the suspension is less than 20mm remaining). Breaking is more stable than expected.
The original idea was to install a PD Valve, but the spring was losing its edge, and the spring felt like it was bottoming out. I think it is a good enough Spring if it can rebound so well even with low viscosity oil.
This was a good experience because Double Column Spring did not have a good impression of Honda's suspension.
But hey, I wanted a more solid Spring than OEM, and I'm not going to buy another one. View detail

MINI LINE Rear Single Shock [MX Series] MX362

Fits: HONDA glom

5/5

Highly Adjustable Rear Suspension for the Grom

About quality and texture: I am happy with the quality of the rear shock absorber from YSS, the construction of this product compared to the Honda one is a huge improvement. All the metal surface and paint finishes are perfect. About the feeling of use: The feel from the rear end is much more controlled now with a suitably rated spring, unlike the Honda one designed for a 60kg rider the YSS shock can handle my 80kg with ease. Products to buy together: Some higher rated front fork springs would also be desirable to purchase along side the rear shock absorber and Kitaco have 5.5N, 6.0N, 6.5N and 7.0N options compared to the Honda 3.8N as standard. Difficulty of installation: The process to install takes about an hour, only 2 bolts holding it in place, I removed the rear hugger, seat and rear plastics then supported the rear of the motorcyce with an A frame and strap. A little difficult to do. Cost performance and comparison with other products: Good costing as you are getting a quality built rear shock absorber with all the adjustments available, pretty much all most people need as compared to the much more expensive Ohlins option that a lot of people go for which is over kill but does look more impressive. About shipping and packaging: Sea frieght is my preferred method of shipping due to the lower cost but not available for this product due to the gas and oil in the product I am assuming. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged. Any concerns, cautions, or advice when purchasing: If you are looking for a fully adjustable and well priced rear shock absorber that will solve all the problems that the Honda one has then look no further.

MONO LINE Rear Single Shock [MZ Series] MZ456

Fits: KAWASAKI VERSYS 650

5/5

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

MONO LINE Rear Single Shock [MZ Series] MZ366

Fits: YAMAHA SEROW225

If you're not sure, buy it!

[How is it used?
The rear shock of SEROW225WE, which is used for playing in the mountains, has become loose and the rear is not settling down. Normal shock overhaul contractor. or else I'm going to replace it with a Replace item." I have checked with several companies that offer overhaul services, but even though the pricing seems reasonable, the price is quite expensive when you add options such as new bump rubber installation.
I decided to replace it with a replacement! I consulted with my friend Mr. Y who was using YSS Rear shock on his SEROW225WE (5MP), and as a result of test riding, I purchased YSS Rear shock.
Was the one you received as per Image?
As mentioned above, I had test-driven the product beforehand and it was just as Image.
Was the installation difficult?
If you are able to remove the normal rear shock, it is not a difficult job.
If you are not confident, ask a friend who can do it or a pro shop.
How was your experience with it?
The overall length of the rear shock itself is the same as the Normal shock, and the spring is a little thicker. Unlike the 4JG4, which was equipped with a separate reservoir tank, the rear shock is an integrated type, but it has a high-end appearance when compared to the 4JG5-5MP4's Normal shock.
When installing the product, the pre-road was set about 15mm weaker than the standard setting by our friend Mr. Y.:The damping was set to Stock (14th Notch from the Hard side) and installed on the car body.
I used it for mountain play after city driving (break-in), but my Level (just a hair above beginner) driving is not good enough. "Exactly good" I felt it.
Pre-road is a little bit stronger than Normal shock, but damping is not so different from Normal. (As for the Flat forest road, we can go there with GunGun and Axel open).
[Included Parts:were they on?
ShockQuantity:SetBody and Pre-road adjustment tool (stick), Installation Instruction Manual and Sticker are included.
[Was there anything that disappointed you?
None at all, in fact, for me, the product exceeded my expectations.
For those who are confident in their skills, there will inevitably be parts that are lacking, but for beginner to intermediate level drivers, there are 30 levels of damping on the extension side (Webike stated 25 levels, but I tried moving it before installation and found 30 levels) + Pre-road (screw type with a wide range of adjustment) + ride height adjustment within 10mm, so it has a wide enough range of adjustment performance. It is a rear shock with a wide range of adjustment and sufficient performance.
Other items that would be helpful
Point and hang of installation
It would be Smooth to remove the exterior (Fuel Tank, Seat, Side cover) and Rear tire (probably impossible without removing them), and please make sure to stabilize the vehicle body properly.
I heard that the Upper Side may need some modification when installing on a pre-4JG4 chassis? Let's temporarily install it and check.
[Availability and clarity of the Instruction Manual
The Instruction Manual is included in the package, but it is so easy to understand that there are no problems for those who purchased this product for this purpose.
[Notes]
As mentioned above, you may be unexpectedly injured if the Motorcycle falls over during the work, etc. Please make sure that the vehicle is stabilized properly.
Although the various parts can be adjusted after installation, it is difficult to change the pre-road adjustment due to the narrow space for access.
[ITEMS TO BUY TOGETHER
Lift upSTAND makes it easier to work with.
[Opinions and requests to Manufacturer
If the price is a little lower, please let us know so that we can purchase a new one instead of Overhaul next time. View detail
