Material: Machined from GCr15 bearing steel (spring hold ring), Hard chrome plating (surface treatment of spring hold ring), Special bearing steel ball (roll ball)
Original system for difficult sliding with commercially available "slide bearings"!
By placing a ball bearing under the slide ring without any gaps, the center spring will not twist and will move more smoothly!
The ball bearing is placed inside the normal cover instead of the common ready-made slide bearing. The spring hold slide ring (movable part) is designed as a spring guide to prevent the spring from opening due to the centrifugal force of high-tuned machines. At first glance, the drivetrain seems to move smoothly, but frictional resistance occurs when the center spring and the torque cam (or the contact surface on the clutch side) twist to operate the torque cam.Torque camshaft strokes up and down while twisting itself, so the more the cam groove (power slit) is laid down to make the kickback characteristic stronger, the more the cam itself moves "while twisting" when it strokes (opens and closes).At that time, the center spring is twisted and compressed, and a strong resistance is created between the two ends of the spring, and in addition to the original force of the center spring, this resistance gives resistance to the torque cam that tries to move by twisting. The two ends of the spring rub against each other and move a little while showing the resistance value. However, this does not allow for a precise drivetrain set-up and smooth shifting.Especially in street battles or lap races where you have to kick back frequently, the drivetrain setting changes from the beginning to the end, and you are often told that your bike is getting tired.The center spring is also not in good condition because it is extending and retracting with the opposite torsional resistance. We have developed a system that allows this part to slide "perfectly" without any resistance and without interfering with the tension value of the pure center spring and the movement of the torque cam. The thickness of the system itself is about 4mm at the center spring receiver, which is extremely thin and does not affect the performance of other parts.
Also, the bearing roll balls are included in the package to make sure that you don't lose them during assembly.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
More smoother on acceleration,better performance in upon open throttler.Extra milleage saver on petrol,could feels e acceleration much better while on the moveView Detail
