It works. It's just expensive!

One of my friends suggested that I change the shaft, and although I had no particular problem with it, I decided to replace it with a new, stronger shaft rather than continue to use the old one. I decided to replace the old shaft with a new one that is stronger than the old one.

[Axle Shaft]
Axle Shaft is a rod that drives the Wheel. The Axle Shaft plays an important role in supporting the Wheel so that the Wheel rotates around the Axle Shaft, and without the Axle Shaft, the Wheel would come off the axle.

[ASKULShaft's role]. ‥
◎Transmits the load input to Tire and Wheel to Suspension.
◎The Bearing, Distance Collar, and Axle Color at the hub of the wheel are integrated and fixed with the least amount of friction.
◎Brake Disc or Sprocket position is determined at the Center of Caliper or Chain line.
It's not just an iron rod. (^o^) /

Replacement of Axle Shaft
The effect that can be felt depends on the type of car and whether it is Front or Rear. 。 In general, the Front tends to increase the lightness of handling, and the Rear tends to make it easier for the suspension movement to be transmitted to the Rider, and the condition of the Tire, including the feeling of ground contact, to be easily understood.
→ I will try Rear!

What is Chromoly? ‥
The official name is Chrome molybdenum steel. Iron Combined Gold with a very small amount of Chrome and Molybdenum added to iron. 。 Specified to contain 0.1-0.5% carbon, 0.9-1.2% Chrome, and 0.15-0.45% Molybdenum 。
No change in strength even in high-temperature, high-pressure environments, and moderate "Shita" The material is used in bicycle frames, crankshafts, stabilizers, aircraft leg parts, etc., to absorb vibration due to its high strength and ductility.

[Merit to Chromoly]. ‥
(1) Rigidity is increased.
Axle Shaft is one of the rigid components of Suspension, so high rigidity and strength are required. 。 Always while driving "distortion" It is the only thing that supports the weight of the car body by receiving the large force from the wheel and suspension. 。
By reinforcing the suspension, the suspension is properly activated against external forces from the road surface during driving, and the tires are stably grounded to the road surface.
→ Improves straight line stability and minimizes yawing during corner rings.
Improved rigidity compared to the→OEMShaft, and increased front ground contact for improved cornering performance.
→Breaking is also more stable, as the back footing is more effective when breaking.

(2) Increased accuracy.
Except for a few special vehicles, production vehicles are limited by cost, and there are many areas in which compromises must be made. 。 The OEM Axle is also not as precise as we would like it to be, due to cost. Simply put, it is made finer than the original Size that we want to make. 。 On the other hand, the external ChromolyShaft is cost-effective and finished to a high degree of precision; the bearing, distance collar, and side color are all in perfect alignment, bringing it closer to the ideal structure envisioned by the developer. 。
The increased axial accuracy of the→shaft reduces Wheel rotation loss and lightens the push/pull.

Merit is all I have, the price is so high (laughs).

Replacement Procedure] It's easy... (；・∀・)
(1) Tire does not fall off (not on the ground) Lift to a degree.
Loosen the shaft fixing bolt on the Right Side with a wrench.
Loosen the Axle Shaft from the Right Side.
Loosen the fixing bolt on the Left Side.
(5) Remove the shaft nut and pull out the shaft.

Effect after replacement ‥
◎The rigidity of the undercarriage has been increased, and it is easy to feel the sense of gripping the tire, giving the driver a sense of security.
◎Because the body behavior is settled, effective Brakes that stop short are possible. In other words, less flexure and more stability than OEM.
◎The rotation of Tire becomes lighter and easier when pushing and walking.

The most obvious was at low speeds. No wobble when starting or stopping. 。 I think this is a large advantage for low-displacement vehicles that cannot use high speeds. View detail

It is difficult to experience as much as the front axle shaft.

Since the front axle shaft was replaced and the impression was quite positive, we decided to replace the pivot shaft as well.
#The Pivot shaft that had been in there before had no particular rust and was not out of Grease.

The assembly was done at the same time as the one-year inspection.
The fact that the Clearance was quite SEVERAL seems to indicate that this is a product that attacked the diameter Limit.
Rather than material strength, the above accuracy is a feature.

In theory, I vaguely wonder if ↓'s positives will occur.
Reduced rattling with the point that holds the shaft.
1:Swing Arm shake is reduced when banking (roll component of the vehicle).
→s ability to take advantage of sus
(The roll component generated by the gutter is reduced and the pitch component is relatively increased.)
2:Decrease in swing arm shake due to driving force transmitted from the Chain (yaw component of the vehicle)
→Tire will now be in series, increasing straight-line stability (closer to the ideal geometry Bird).
3:Decrease in blurring during acceleration and deceleration (Radial component of the vehicle)
→ braking and acceleration become Direct (rigidity of the connection between the Swing Arm and Frame is increased)

Compared to the Front change, I have to admit that the change in Pivot shaft change is difficult to understand.
It is somewhat tough to find a difference in Window shadetest.
The following is a sense of what it feels like when you try different things and pit them against logic.

Small turning is now Quick→1
The way traction is applied when →bank→Axel is on has been improved (I think).
I feel less tired when driving long distances &arr;2
I no longer feel fatigue on the left hand side, which I used to feel often, and I also feel less tired after long distance driving, probably because of this.
(thanks to the alignment of the geometry Bird due to the tilt of the Swing Arm towards the Chain side?)

Also, as a point of change, the vibration of the Engine seems to have decreased.
Maybe the movement around the Pivot axis has become more straightforward, allowing vibration to escape from the Frame through the Rear suspension? It may be just my imagination.

Based on the above, the product seems to be especially Merit for those who do Sports driving, where the suspension is fully used.
Also, if there is dissatisfaction with Suspension even in STREET use, it should have a certain effect. View detail

Satisfaction level is high.

Since the rear axle was out of stock, it was replaced at the same time as the front axle.
The quality is very high and excellent.
First of all, the weight is totally different from NORMAL.

After riding the car, it is clear that the Rear suspension is doing a good job by increasing the rigidity of the Rear.
It is the feeling that the Swing Arm moves vertically up and down without any blurring.
My motorcycle is equipped with the OHLINS Reserver tank model, which has improved the ground feel and road-following ability, so the ride quality is relatively better.

Personally, I am satisfied with the Large change, but I guess the only Neck is the price. I think it is a bit expensive in terms of cost-effectiveness. I think it is a bit expensive considering the cost-effectiveness, so I gave it a 4 star rating. View detail

Note that the head will be 1SizeSmall.

Replaced OEM Shaft as DAX Swing Arm Pivot Shaft.
It looks Plating and very beautiful, and is a little bit rusty OEMShaft.
Obviously there is a difference, but when you put it on, you can't feel the difference...
In other words, DAX's Swing Arm is extremely reluctant to move when the shaft screw is tightened.
This would affect ride comfort and handling stability.
I had been adjusting and tightening the OEM with double nuts for almost 3 years.
Since there was no maintenance, the Swing Arm was reluctant.
This replacement and maintenance will allow the Swing Arm to work cleanly and
The ride was very comfortable, but I could not clearly see the effect of these Parts.
It may be a good idea to think of it as a replacement that also serves as maintenance.

At any rate, when I drove the car after the replacement, the rear tires moved much better.
It seemed a little harder to turn. View detail

Pivot shaft replacement for 2021MT-09SP

Pivot shafts for the 2021MT-09SP, which were backordered, have been delivered and we immediately replaced them.
However, it is a simple work to loosen the nut, replace the shaft, and tighten the nut with the specified torque. I put the footpeg on the footpeg as shown in the 6th picture and the rear tire is supported by the tire clamps.
The nut is Torque 105N tightened, so it was loosened quickly with an impact wrench.
Shaft is supposed to be 0G, but I could not pull it out by hand. I lightly tapped it with a plastic hammer and it was tight only at first and then I could pull it out by hand.
Next, after applying a thin layer of grease to the shaft made by KOOD for replacement, I inserted the shaft into the pivot hole, but the hole position seemed to gap slightly on the Left Side of the body and it did not go in until the end. I tried to lift up the Rear Thailand and push it to the Left Side, but it didn't work well, and I thought it is not recommended to do so because I have another work to do. (Sweat).
At any rate, now that the Shaft is Penetrating, the Nut is tightened at the specified Torque to complete the process.
It seems that Thread compound application is recommended for Nut to prevent galling.

I have only done some light driving in the city, but to be honest, I have not noticed any large changes like I did when I replaced the front axle.
However, now that we finally have Front, Rear, and Pivot made by KOOD, I feel Refreshing.
Perhaps a comparison of riding with OEMShaft and replacement, or replacing all three at once, would make the difference feel more Large.
We replaced the Front first, then the Rear, and finally the Pivot, so we may have become accustomed to the changes.

Compared to OEM products, Pivot shafts have a very high level of precision and quality, and can be expected to provide a sense of ground contact and rigidity, but I still thought that Pivot shafts are a little difficult to afford in terms of cost. View detail

5/5

Front, Pivot, and Rear are all Complete!

What made you decide to buy?
We're on track for 2021! Stock and replace the remaining Shaft at once!

How was your experience with it?
If you compare it with KITACO's Hollow Shaft. "Magical stick" ChromolyShaft, also known as!
Whether the coefficient of friction is Small or "Magical stick" It's not a cheap part, but it's an excellent product of Made in Japan Quartier that only owner who replaced it can feel and pursue to the material.

What is the point or hang of the installation?
Pivot part is the fulcrum of the rear arm, so it is difficult to work on it every time. First of all, work carefully so as not to knock down the car body. Since the front axle shaft was replaced before, use the axle shaft that was removed and stored. The rear axle shaft of G-Craft Swing Arm is shorter than the front axle shaft. If I had the OEM rear axle shaft, this work would have been easier.
Once the KITACO hollow shaft is removed, apply Urea grease to the KOOD:Pivot shaft and carefully push it in from the other side with a plastic hammer. Push it in carefully from the other side. If you don't work carefully, you will damage the screw mountain, so be careful.
Tighten the rear suspension lower bolt at the specified torque, apply nut to the pivot shaft, move the swing arm at 1G to acclimate the pivot, and then tighten the torque wrench at the specified torque to complete the job. View detail
