【AFAM】Rear Sprocket (Steel) Review

AFAMAfamRear spokeROCKET (Steel)

I was looking for a Steel spot ROCKET that can be used with GSXR110 Wheels.
I think they will last longer than the ones we used before.

Unfortunately, it is Painted. View detail

Merit of de iron is not cosmetic.

OEM steel is fine, but if you want to change the number of teeth, you will need to use an external product.
However, extremely few people go to the trouble of replacing a Sprocket and choose steel.
Even if they were there, they would most likely purchase an OEM Iron Sprocket.
That is why Aluminum Sprocket is sold by various companies, but there is seldom a Sprocket for AfterMarket made of iron.

In addition, a large majority of those who dare to prefer the Iron Sprocket will be those who value durability!
Or it may be important that it is less expensive than Aluminum.
In a word, it's all about cosmetics.

However, the Merit of the Most Large of the Iron Sprocket is not cosmetic.
The Merit of iron is that it can maintain the good tooth shape when new for a long period of time!

When new, there is no difference in tooth shape between aluminum and steel, but after 3000 km, aluminum will begin to wear off.
However, if it is made of steel, it is not worn at all, and the slight difference in tooth shape at this time can be felt as the difference in smoothness of the drive.
If you use it for 5000 km, you should be able to feel it as a very clear difference.

This is because a slightly reduced tooth will cause the chain roller to move as if it is caught, even if there is no problem with the drive, and the feel will deteriorate.
It's not enough to say it's decreasing visually…, there's a pretty clear difference even if it's only a 0.1mm decrease.

Since steel products are unpopular, they are almost always ordered on a made-to-order basis, and delivery time is often several months.:In many cases, it is likely that Aluminum is being purchased.
However, for the purpose of maintaining proper tooth shape for a long time, you should wait and use steel.
Long delivery times are addressed by ordering earlier and earlier.

Material:Since it is heavier than aluminum, it should be disadvantageous in suspension operation due to the increased weight under Spring, but such negatives are not felt at all.
I think Merit outperforms it because of its longer tooth shape maintenance time, which means that the driving resistance does not increase as the distance is increased.

I don't know if the color of Afam's iron Sprocket varies depending on the order lot or if the specs have been changed, but the last time I ordered one, it was silver (Uniqlo plating?) with a textured surface finish, while the one I ordered this time was painted black,
Black paint has a smoother surface and is easier to clean, so hopefully it will stay Black paint Spec. forever.
The numbers are actually black. View detail

Used for SA11A

I tried to order an OEM Sprocket but it was rusty and cost about 9,000 yen.
It is not listed in the compatible car models, but it was a simple installation on an SA11A. View detail

I would like to use it again.

I was able to purchase this product at a much lower price than the OEM Product. The product in the picture is unpainted, but the one I received was painted black, so it may be good or bad depending on the person. View detail

For use with models other than TL250SB

Material of AFAM while NORMAL is 58T:Aluminum56T was attached but was replaced due to the limit of use.
Since most of the time we are driving around town or short touring within 100 km, the low GEAR of the tiger car was very hard to handle.
This time, I dropped it down to 47T, which is very comfortable for the aforementioned riding style, and I have no problem starting from the first gear (I was starting from the second gear before the change). (I was starting in 2nd gear before the change.)
Since it is made of steel, it is expected to have a long life. View detail
