【AFAM】Front Sprocket (Steel) Review

I used it on my ZXR400L.

I bought it because of its low price. It is a safe Brand. View detail

After considering manufacturing quality and precision, as well as ease of availability

MY2010 F800GS is mainly used for touring and city driving. Although the mileage is not so high, the fee ring around the drive parts is not good and some drive noise is bothering me, so I replaced it.
We purchased this product after considering OEM Parts and each AfterMarketParts. I was concerned about the manufacturing quality and precision. Although it seems to be an imported product (even the manufacturing plant is unknown), it has the JapanFOR JAPAN MODEL inspection seal, and there are no particular concerns about its packaging, material, or processing.
The screw lock agent left in the hollow receptacle screw of the drive shaft (output shaft) was removed as much as possible during installation, and the splines around the outer circumference of the shaft were cleaned, greased up, and the purchased sprocket was installed.
There was no strange sticking feeling or strange rattling, and the excess grease came out in a beautiful flower shape (splined shape) evenly etc. from the gap between the shaft spline and the inner circumference of the Sprocket. This suggests that the machining accuracy of the Sprocket is not bad.
Check the front and back of the spring washer holding down the Sprocket and tighten the specified Torque through the Spacer. (50N・m) Tighten the right screw in the direction of the crank rotation. The usual method to prevent the Sprocket from rotating with the shaft is to apply a chain to the Sprocket before tightening it, or to prevent the Sprocket from rotating by applying driving friction with the chain or by applying a rear brake, but this will not work. However, this will cause the Sprocket to be pulled downward by the weight of the Chain and toward the rear wheel by the tension. I was able to fix the center of rotation of Shaft and Sprocket by gradually increasing the torque setting with the gear in 1st gear and without applying the chain. If you have a problem with the torque setting, this method seems to work fine.
The OEM parts for this year's model that were installed in new vehicles seemed to be made by ZF, but both the OEM parts that came with the vehicle and the products we purchased this time had a solid industrial feel, and I personally have a good impression of them.
Items that may be helpful in the replacement process are a torque wrench and a medium-strength screw lock agent.
AfterMarketParts has a variety of products, but we strongly hope that you will continue to supply products that emphasize material, precision, processing technology, inspection and quality control, and not just price competition. View detail

Driven Sprocket Replacement

In addition, the company has been working on a new project.
I searched for the same item and found that SUNSTAR has discontinued (?) the same part number. I found the same part number in SUNSTAR.
What SUNSTAR has is Quantity with Driven Sprocket:Set product with only the OEM Standard 17T-44 gun combination.
I looked for a replacement and finally found an AFAM 18 gun.

The reason for the change in the number of Sprocket's Ding, in the Number of teeth on the OEM.
(1) The response is peaky, making it difficult to handle in some situations.
(2) Tight HairpinCorner cannot be held back in 2nd gear, and the Torque is insufficient in 3rd gear.

By changing the number of pins, the Tight HairpinCorner can be used in either 2nd or 3rd gear, making it easier to handle.
Therefore, we chose AFAM to maintain that setting.


However, it takes about two months for delivery, which is unavoidable due to the order-made nature of the product.
I placed an order on 3/9 and received emails on 3/10, 3/14, and 3/15 informing me that the order was being arranged.
No progress report for about a month after that. (This is not good.)
4/17, The item is out of stock and the current estimated delivery time is three weeks." and then a confirmation whether to continue with the order or to callcell.
There was no alternative and we decided to continue ordering.

I received an email on 4/18 with a shipping notice (what the heck? This!!!!!!!!!!!!!!!!!!!!!!!!!!)

Arrived 4/19. (It took 40 days from order to arrival.)

4/27 installed at my favorite Motorcycle shop.
While replacing the Sprocket, we also decided to replace the Bearing and Dust Seal.
I thought about replacing it myself, but there was no SST and I gave up.


Impressions after the replacement are the same as before (laugh), easy to handle. View detail

Same number of dings as OEM

AFAM's 47 Gold sprocket and RK's Gold Seal Chain 520-110 and Quantity:I can ride with the same OEM reduction ratio of F14-R47 without any discomfort, but I really wanted to have more low speed punch, and after worrying about F13-R45, I came to a conclusion. I was really looking for more punch at lower speeds, so I decided to go with the F13-R45 after much consideration. View detail

Used for CB250RS-Z

[How is it used?
Used on CB250RS-Z.
I was wondering what to do about Front sprocket for the same car model because the only compatible products were XAM or JTSprocket and I was worried about the delivery time.
I was wondering if the Sprocket for the car models listed in the XAM compatibility list would work. So I looked into it and found this product in stock and purchased it.

Was the one you received as per Image?
I was a little concerned about whether the product would really work because the product image looks like an image and is different from the actual product.
As a result, there was no problem.
Also, the package was already opened, but the individual packages were unopened, so I used them as they were. The package was unopened, so I used it as it was.

Was the installation difficult?
It is easy to remove and replace the Sprocket Cover.
Don't forget Torque management as it will be the driving part.

How was your experience with it?
It was from the OEM that originally came with it, but there is a little rattling against the shaft. (Maybe it was like this from the beginning?)
There were no particular problems with driving.
Not sure about Life as it has just been replaced.

[Included Parts:were they on?
SprocketBody only.
If you want to replace the Plate and Bolt as well, it is safe to buy OEM Parts.

[Was there anything that disappointed you?
None in particular. Don't be fooled by the product images.

【Review】
Nothing in particular has been improved! I have the impression that Sprocket is a safe and reliable product.
It was helpful to have a Lineup of old cars. View detail
