SR400FI 유저입니다. 적산 2.7만km에 위 상품으로 교환했습니다. 기존 순정품도 상태는 양호했으나 추후를 위해 오일과 함께 교환하였습니다. 초반 순발력에는 변함이 없으나 체인 사이즈가 커져서인지 주행 중 리어에 무게감이 느껴집니다.

** Regarding chain link count: For parallel import vehicles or older models, the required link count may vary due to country-specific specifications or modifications to the chassis. If the chain is too long, please cut it to fit the vehicle. If the chain is too short, please contact us before performing any riveting work.
* For conversion kits, the stock chain size cannot be used; you must perform a chain size conversion.
* The color and shape of the delivered product may differ from the images.
* Please note that significant changes from the stock sprocket tooth count may prevent installation on some vehicle models.
* Durability is a reference value and is heavily influenced by riding style, chain size, and maintenance condition.
* Offset values apply to the sprocket only.
* The actual chain line offset from stock varies by vehicle. If the stock sprocket has an offset design, that value will be subtracted (varies by vehicle).
* Not all listed tooth counts are guaranteed to fit without interference. Please verify fitment for your specific vehicle and chosen tooth count.
* Lightweight holes are not present on all sprockets.
* Specifications are subject to change due to manufacturer requirements..
* The image is only for reference. The image shown may differ from the actual product.
A convenient drivetrain replacement set packaged with a chain and front/rear sprockets.
This set is configured with the stock front and rear sprocket tooth counts, eliminating the need for complex selection.
The chain is from a trusted brand, and the sprockets are manufactured by Sunstar, known for high circularity and high OEM adoption rates.
Recommended for those who need regular replacement parts but are unsure which to choose.
Except for some models, the rear sprocket is made of duralumin. Even with the same tooth count as stock, you can expect improved handling due to reduced rotational weight.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.

Fits:YAMAHA SR400 SR400 1988-2021 (520 conversion)
Oct 8, 2016
It was easy because it became a set
SR 400 The year 2000 drum final mold. If I think about 28,000 km once in a chain - Since I did not want to replace sprockets, I finally exchanged. I asked BIKE store to change according to vehicle inspection. Secondary reduction ratio is genuine 2. 947 This item 2. It is almost the same as 933, but 60 km before replacement at 6500 km after replacement at 5 th speed 3,000 rpm. Perhaps the previous sprocket has decreased considerably. Although it converts from genuine 428 to 520, it does not matter the sound. Drive for SR - Driven sprocket, because the chain was set, we could save time and effort to think about the combination.

It is a classic 520 Conversion.
Chain of 428 Size of SR 400 OEM is changed to Chain of 520 Size, Set which can exchange Sprocket before and after.
I decided to exchange it because some sticking of LINK part of Chain's Piece I used to date came out.
For replacement work, some OEM Parts Number will be required, so we recommend you to order at the same time. You can easily search it from Yamaha's Parts List.
Chain seems to be designed with an X-shaped O-ring suppressed Friction loss, but it seems that because of the high viscosity of the protective Grease applied to the new article immediately after replacement, the acceleration feeling improved so much There was no real feeling. After running for a while, I felt that I was accelerating very strongly with Smooth after cleaning hard and lubricating after a hard Grease dropped. If possible, it may be better to wash away protective Grease immediately after installation and make it move to Smooth from the beginning.
Regarding the driving sound, too, the OEM 428 Size seems to rise in rank order, so I am a little worried if I do not get used to it.
Drive sprocket is the direction to install (Front and back) I was wondering which way to do it. Unlike Driven Sprocket which can be judged at a glance, Front is hard to see. In my case, I mounted the face with the number of engraved marks facing outwards, and the Chain line came out, so I judged that it was good.
Since this handling instruction manual is not attached here, I think that it can be relieved in amateur work if attached.
Since the number of front and rear Sprocket chose the one closest to the reduction gear ratio of OEM, we can drive without any discomfort without losing balance of OEM.
Regarding the reduction ratio, it depends on the Tuning state of the Engine and how it is used, but I think that it is safe to follow the reduction gear ratio of the OEM if it gets lost.
