【RADICAL】Chromoly Swingarm Pivot Shaft Review

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

Change…… … None?

I changed the shaft of TRX850's pipod. When I was servicing my trx850, I often found that the split pin hole caused the screw threads to lick even though I was tightening the screws normally. I bought this as a countermeasure for that, so I don……t know about Chromoly or anything like that. However, since I used OMEGA for the Grease used when replacing it, I felt the movement was good. It is moving flexibly with suspension! It feels like it is moving smoothly. It may be my imagination, but since there are no more OEM parts, I am very grateful for this kind of parts. View detail

Chromoly Front Axle Shaft was good

I exchanged Chromoly Front Axle Shaft and found more performance than I expected, so I will exchange PivotShaft without hesitation.
The CB 1300sf is old because the design itself is too heavy, and because it was built for the purpose of Touring, there is impossible for CornerWork at the same speed as SS etc?
For such Motorcycle, I feel that it is perfect Parts for the rigidity up of Front, Rear, Pivot.
RearShaft is also planned after replacing PivotShaft.
I feel Cost performance is good. View detail
