[Description]
BORE ACE has pursued the lightness which is the biggest weapon of SR.
[installation point]
・Please remove the stock hub damper and clean it.
・The area where the stopper pin is inserted is often swollen and the diameter is changed.
・Remove burrs with paper or the like.
・Please try to install it temporarily without the rubber damper.
[Q] Why does the stock have a grease nipple and BORE-ACE does not?
[A] The axle of the wheel side is made of iron.
The inner diameter of the stock hub damper is made of steel.
So it has a nipple to prevent it from rusting and sticking.
Other manufacturers' hub dampers of the current type do not have nipples, of course.
The BORE-ACE is made of machined aluminum, so it doesn't stick and you can use grease as installing it on.
O-rings are inserted in three places to provide damper performance and prevent water from entering.
[Q] Why does the stock one get rattled?
[A] As written above, the rust will be removed from the place where the oil is cut off, and it will gradually become rattled.
The stock unit does not contain an O-ring, which allows water to enter the unit due to its structure.
There is a custom version with an O-ring in the upper lid, but it is better than no O-ring because the O-ring can absorb much more than the lid can.
[Q] Why does the stock one get rattled?
[A] On SR400 / 500, the pivot shaft of the swingarm is located in a special place, so if you put too much tension on the chain, it will pull the sprocket too much when the rear shock is bottomed out, and it will become rattling gradually.
The lighter the bike, the better the performance and the more comfortable it will be to ride.
It is made with durability in mind, so please feel free to use it.
When installing sprockets, apply thread locking agent.
