Large humanized color and excellent cosmetic performance
[How is it used?
The OEMSprocket on a YAMAHA XJR400R was quite worn out, so it was replaced.
I regretted a little bit that I should have done it earlier since the change was made after 38,000 km of mileage.
The number of pins is 45, the same as the OEM.
Cost performance is good, and there is a wide variety of coloring. We chose XAM because of its reasonable price and reliable manufacturer.
Was the one you received as per Image?
It was just as Image.
I was wondering about SUNSTAR, but for some reason I couldn't find 45 guns for SUNSTAR XJR400 in the lineup on webike,
I chose this item because it was on sale at a discount.
I especially liked the colors.
The color is somewhere between Bronze and Gold, and I think it has become a Large Custom with no strange gaudy feeling.
Was the installation difficult?
This was the first time I tried to remove the rear wheel and it was surprisingly easy.
Sprocket replacement is also easy, as it is simply a matter of aligning it with the hole where the Bolt enters.
The only thing left to do is to tighten it firmly to the specified Torque. If you have the proper tools and knowledge, you can do it.
How was your experience with it?
The driving feeling was very light.
This time, the Hub damper and Chain were replaced at the same time, so it is hard to say that this is the original effect of Sprocket, but it is a Large Advantage because it is lighter than the OEM Steel.
Since it is aluminum, I am concerned about its durability, but if it lasts more than 10,000 km, I would personally be very grateful for Large.
[Included Parts:were they on?
Nothing in particular, but I thought there was no Instruction Manual or something like that, but it was written inside the Case.
I noticed it when I was throwing it away and ended up not reading it lol.
[Was there anything that disappointed you?
Not so far.
I've read in other reviews that the anodized surface peels off quickly, but I think that's just because the surface seems to be treated with Teflon.

ITEMS TO BUY TOGETHER:Driven Sprocket and Chain, Hub damper also changes a lot when replaced together.

It was a darker Bronze color than the picture.
I fell 200 times rolling over on 2 Ding Down.
I thought it was Gold in the picture, but it was actually a Bronze color.

Accurate and lightweight
I bought this for Circuit.
For MINICourse is swinging to the side with the show.
Lighter weight compared to OEM helps reduce load under Spring.

be very light
The brown color is very luxurious. It weighs one-third compared to the existing standby gear. It's quite light, so I'm a bit worried about its durability, but I'm satisfied. View detail
Used on SR400 final
SR400 FINAL Used in OEM condition, exhaust system, intake and exhaust, ignition system and all other systems are full normal.
First, the Front sprocket is set to SUNSTAR SUNSTAR:221-20 Replaced with 19T→20T.
After driving about 500 km at high speed, I felt that I could still make it high geared, so I looked for a Front 21T and found one made by RCE EngineerRing. When we contacted the manufacturer, we found that the product was discontinued and could not be obtained.
Then, we changed our policy to change the rear sprocket and searched for one that was compatible with the OEM428Chain and found the following. The smallest 51T was selected.
I would have preferred Steel for its durability, but could not find it.
XAM XAM PREMIUM Series Rear Sprocket
Item number:A3207X51T
It was nice to be able to install the OEM428Chain as is, with no Conversion required for the 520Size and no Chain piece stuffing.
Now Front20T/Rear51T with reduction ratio 2.55 ← OEM 2.947 19T/56T
In this condition, the Meter reading was 4100 rpm at 100 km/h cruise, and I could drive with the flow without numbness in my hands, even at a crowded highway. After traveling a total of 650 km on the Kita-Kanto, Joshinetsu, Hokuriku, and Kan-Etsu highways in this condition, I have no problem at all cruising at 100 km/h. Overtaking lane 110-120km/h is also possible. It is possible to climb a hill on the highway at 100km/h with 5th gear. The maximum speed in 5th gear is 125km/h. Also, on ordinary roads, 5th gear is useless at speeds below 60km/h, but this is not a problem at all since the car can be driven in 4th gear. In fact, when driving in Bypass, it is possible to drive at 80 km/h in 5th gear at 3000 rpm, which is comfortable and pleasant. Acceleration is reduced, but it is acceptable.
We recommend this Spec. for SR400Rider, which is mainly for touring.
I would like XAM to produce a Stainless Steel Sprocket, and a 50T Sprocket.

Hard DuraluminSprocket
[How is it used?
I bought a high quality Sprocket as the GEAR ratio setting was set (and consequently replaced and removed further …).
Was the one you received as per Image?
The Duralumin shade is very nice, dull and not too flashy. Lightweight and no BALI, very nice shaping.
Was the installation difficult?
General Sprocket replacement can be used.
How was your experience with it?
I don't see the benefit of weight savings … it looks better.
[Included Parts:were they on?
There is no Bolt or Nut, so it is an OEM diversion.
[Was there anything that disappointed you?
It's not cosmetic other than the way it looks….
