[How is it used? Course and Enduro with CRF125F

Was the one you received as per Image? I used DID for the 520 Size, so I tried RK for the first time for the 428 Size. The color of Gold in RK is like a strong and flashy Gold with a yellowish tint.

Was the installation difficult? I chose the Clip type, so it's easy.

How was your experience with it? No problems, normal.

[Included Parts:were they on? Joint Attachment

[Was there anything that disappointed you? nothing special

I heard that the OEM non-seal chain of CRF125F would soon stretch, so I searched for a seal chain to replace it with a 428 size seal chain. I usually prefer DID, but I thought CRF125F does not need so expensive one, so I decided to choose RK's product because of their claim of RACINGChain.

I bought it for driving on forest roads.
Since it is not a seal chain, the operating feel is light.
It is easy to handle because it can be washed entirely with kerosene.
If the chain lube is not put on properly, it makes a squeaky and Gold sound on the way back after driving about 100 km round trip.
I think the durability is high, and I think it's as durable as the Seal chain.

the best part
It is a RACINGChain, so the width is narrow.
Clip joints are easy to use.
Gold in color.
Long-lasting.

bad point
When GB520KZU was painted Gold.
It was brilliant, but since this mxu
Anodized, Black, and Color:Unpainted's

[How is it used?
Model used:TS125R
Driving application:Off-road driving (Motocross play)
Period of use:About 2 years or so
Used for Conversion from OEMChain size428 to 520Size.

Was the one you received as per Image?
As per Image. felt Gold was more flashy than DID.

Was the installation difficult?
Since I did not have a Caulking Tool, I asked the Shop for one.
If there is a Caulking Tool, there is no problem as long as you have enough time and do not Crimp too much.

How was your experience with it?
With the OEM 428 Size, the clip joint was damaged when landing on a jump, and the 520 Size did not have such a problem, which increased the sense of security.
Also, compared to DID's Non-seal ChainERT2, the Chain width is not that much wider, as advertised. I felt it was as advertised.
Usability is installation vehicle model (D Tracker) Although the two products are different, we felt that this product had less Friction and the movement was Smooth compared to DID's VT2.
Plating in gold is also more flashy in this product, and if you like flashy, this one can be recommenedation.
Because it is a seal chain, there is not so much growth, and the maintenance cycle is not so large. (Refueling) The new system also eliminates the need to do this every time the car is driven, reducing the amount of time and effort required.
Conversion installation on TS125R was normal with no interference.
