![Racing Weight Roller 20×12 [13.0G]](https://img.webike-cdn.net/catalogue/images/13921/ksw-2012-130_1_TS.jpg)

Good cost performance, durability, and quality
The 6 pieces are under 1000 yen, but the pieces under 13g are finely lineuped in 0.5g increments, with little variation in weight, and the Edge is rounded and carefully finished.
Also, although the durability is not specifically claimed, it is good with almost no wear even after 10,000 km of driving, with only the Light tune level of the drive system and some Engine tinkering.

I appreciate the fact that they sell Single Body for consumables.
KOSO Pulley kit is required since the OEM Slide Piece is no longer available.
Some manufacturers do not supply small consumables like this, and have to replace them with kits for small items, so it is nice to be able to supply only consumables at a reasonable price.
However, I feel that the durability is lower than NORMAL, so I would like to see the durability increased.
The Weight Roller and Belt are still usable after 5,000km, but the Slide Piece is worn out and the Ramp Plate and the Gold part of the Pulley are touching each other. (Molybdenum grease is applied to the Slide Piece)

For those who have trouble driving at high speeds ...
I bought it because the maximum speed is a heady 114km and I was wondering if it could be a little more.
Spring replacement was a hassle, so I kept the OEM Clutch Side and replaced only the Pulley Side, which gave me 120km on level ground and +10km if I tried hard. (*Speed based on Meter reading)
The OEM weight roller may have been worn out, but the mid-range acceleration is no longer sluggish, and the car feels as if it turns from bottom to top without any stress.
I was expecting a drop in fuel economy, but I am very happy with the overall results, as I am getting about the same mileage when I commute to work as I did before the replacement.

Excellent cooling bell for clutch
About quality and texture
The clutch drum is made excellently, it is stamped steel, which has several advantages over the stock drum - improved cooling and reduced weight, which greatly helps with acceleration without losing dynamics due to spinning up excess weight + an increased number of high-quality starts from a standstill due to reduced clutch heating
About the feeling of use
After installation, the quality of clutch cooling has noticeably increased, it stops “floating” after 5-6 sharp starts from a standstill, now it can withstand about 8-9, which is a worthy increase, considering that the scooter is not a racing scooter
However, for transmission tuning this component is necessary
Products to buy together
There is no need to purchase anything with this product.
Difficulty of installation
Easy installation instead of the original drum, just unscrew 1 nut and replace the drum
Cost performance and comparison with other products
Low cost and complete monopoly, as for the Address 125 there are no other similar transmission tuning parts
About shipping and packaging
Good packaging in a blister plus webike packaging in the box itself, the product was not damaged upon delivery
Any concerns, cautions, or advice when purchasing

Quantity:I guess it's not as effective as a Set thing.
Standard Quantity:Since the set product was incorporated as it was, the effect was unknown, but when I actually rode it, it responded well.
I think I could enjoy setting the weight roller by adjusting the weight roller, but I probably won't do it because the work is too tedious.

Koso Lightweight Drive Face for my Yamaha NVX 155 / AEROX 155
The quality of the product is undeniably excellent. After I change the parts, I can feel a significant upgrade. This part upgrades my acceleration and my top speed. It's quite easy to install. No problem at all. Plug and Play just for Yamaha NVX and NMAX 155. Besides the significant upgrade in performance and response, the quality is very good.
It took less than a month to receive the item. My address is in Malaysia; it's quite far and understandable. Usually 1 month.
Well-prepared box to ensure the product arrives in good condition.
Overall, it's a great product and highly recommended.

OEM and Size are different so they don't fit. Defective?
With the right tools in place, installation was a breeze.
However, the dimensions seem to be a little different from the OEM and the Belt does not fit tightly.
Pulley surface has play and wobbles even when fixed
Quantity when riding for a few days to see how it goes.:The reinforced belt I bought in a set was torn to shreds when the drumstick snapped….
I returned it to OEM and it was just past the return period.
It became just Garbage.

The maximum speed can be increased by adjusting the large opening width.
Pulley and Clutch were also from the same Manufacturer, so we chose this one.
Depending on the drivetrain settings, it can be faster and more fun to ride.

Good
After the replacement, I feel that it is better than the original one. Durability will be known only after riding it, but I am satisfied with it for now. View detail
Koso power kit
Installed this kit on my 2022 honda adv 150 US version and man, it was what my bike needed. It comes alive at takeoff and doesn't stop till i hit the rev limiter. This is better than the S23 brand they sell here in the USA. 16 gram rollers is spot. View detail
Drive Series Set
I think this price is a good deal for the price including Face and Center spring etc. in addition to Pulley.
My impression after incorporating and using all...
Only the sound seems more energetic.
In the case of NORMAL, it is sufficient to replace only the Pulley, Face, and Clutch Spring.
Center spring is for high tuning such as bore up.
I can't answer what g was good for WR because I have my preference.
I think the maximum speed has been increased.
However, I think this Pulley is more focused on city-riding fee rings, so you should expect it to be able to keep up with other Motorcycles and SignalRace.
I think the re-acceleration performance is good, I like the Curve and the Curve start up at intersections.
Perhaps it would be better if it was Gymkhana.

Acceleration faster
My motorcycle is YAMAHA NMAX155. After riding for more than a year, this bike will vibrate very much when accelerating, so I bought this KOSO competitive Pulizhu on my webike. After replacing it, the start becomes light Many, the acceleration has also become faster, the shopping price of webike is cost-effective, and the accessories are authentic! -------------------------------------------------- -------- My motorcycle is YAMAHA NMAX155.

Parenthesis good but invisible.
Following the PowerKit and SPORTReinforced Clutch, the Clutch Outer was also replaced. The price is quite expensive, but the manufacturer recommends replacing the outer clutch at the same time as the clutch, so I decided to replace the outer clutch. Well, it may be a compatibility with Shoe.
The actual weight is 825g, which is only 5g lighter than the OEM. The width of the shoe contact surface is 1mm wider than OEM. I didn't feel any change in ride quality by replacing the clutch outer.
It looks good in parenthesis, and the tension is increased when working on it, but in the end it is not visible. The large wall thickness seems to have a good cooling effect. However, the Clutch is not used that often in Shiga Prefecture, so there may not be much benefit from it.
I'm going to finish the Custom for the drive system once and for all; the selection of the Weight roller may not be fully packed yet, but there's no end to it if I'm doing it.

Shoe area doubled
Following the conversion of the pulley to KOSO's PowerKit, the clutch was also converted to a SPORTReinforced Clutch. when the PowerKit was converted, the RPMs were too high for normal city driving and the vehicle speed was not increasing after 100km. We changed the center spring to AdvancedPRO, the weight roller from 16g to 18g, and the pulley boss +0.5mm to the same length as OEM at the same time.
As for the Clutch, the first thing to notice is that the shoe is much larger than the OEM version. The material also seems to have a good bite, and is considered to be much stronger against slipping. The Clutch Spring seems to be a little stiffer.
The clutch spring has been strengthened and the clutch in has been increased by 500 rpm to 3000 rpm compared to the OEM. I think this is the benefit of this change, but the data from the acceleration test up to 20km/h was slightly better. I thought it might be jerky and difficult to handle at low speeds, but it was not to the extent that I was concerned about it. The weight has not been reduced, and there does not seem to be any dramatic change compared to the OEM. Conversely, I can say that there are no strange Minus aspects.
Since the manufacturer recommends replacing the clutch outer at the same time, we plan to finish this drivetrain custom by replacing the clutch outer at the end.

You can feel the acceleration improving.
Weight roller17g(-3g)Center boss−I was riding with 0.5mm Spec. but I decided to incorporate KOSO's PowerKit because the rpm during shifting was at 6000rpm, a little lower than the delicious rpm.
Pulley is 2mm larger in OD than OEM, 126mm larger, and the gap with the case is only 4.5mm. 16g weight roller is 4g lighter than OEM. The center spring is spec'd at +1500 rpm. I think it means that the gearshift speed will be 1500rpm higher.:I measured the Set pressure and found it to be 42 kg, 4 kg higher than OEM. Free length is 133mm, 9mm shorter than OEM.
The gearshift rpm is now 1500 rpm higher than the Spec. In the Zero acceleration test, it was 0.2 seconds faster up to 20km, 0.4 seconds faster up to 40km, and 1.1 seconds faster up to 60km, and I feel it is much faster. Acceleration from AxelOFF is also good.
I had heard in advance that the maximum speed would drop even if acceleration improved, so I checked the maximum speed as well:the speed increase became worse after 100 km, and even worse after 105 km, but finally it reached 115 km, which was only about 3 km less than before the conversion. However, before the conversion, it was accelerating smoothly up to 110 km.
I am planning to add a Sports Clutch, so I will try to see if the acceleration past 100km/h can be improved a little more at that time.

Buy it
This torque driver definitely changed the driving experience for my Zuma. It held higher speeds easier and helped me get a few more MPH. Definitely worth the buy. I recommend this to anyone who is trying to upgrade their CVT for more efficient speed and riding fun. Koso has not let me down and continues to make me a very satisfied customer! View detail
The Screw part was too long to use…
In my case, I tried to install the Sensor via Adapter on my CB1100, but the part where the Screw is cut was too long to fit.
Also, Bolt is also Large, so diversion seems to be strictly necessary.
It is very inexpensive for its price range, so it looks Large sturdy if you assume machining or if you can afford the length of the Oil drain Screw.

It's nice to have a wider range of Settings.
I had been using NCY's Pulley face for about 20,000 km, but the face surface was starting to wear off, so I looked for a new face and bought this one.
NCY has been used up to now.
14 degrees 90g Flat where the boss hits
The new KOSO is
13.8 degrees, 114g, Type with a dent where the boss hits.
The angle of the Face surface is not stated in the product description, and after inquiring with KN Planning, we were told that it is 13.8 degrees.
I didn't have room for a Bose Washer at NCY.
KOSO can add as much as 0.5mm without difficulty, so the range of setting is wider.
