The material is ok. the outer dimension could be more accurate to speed up the fit, because the inner dimension needs to be slightly corrected - but this is an advantage of these bushings. The price glaringly, because a kpl for both lags is about 100pln.
Products perfect, thanks to fast delivery my husband was very happy, because he could spend the night repairing his old Yamaha. And I, thanks to this, I could finally get a good night's sleep. I recommend 100%.
The set was not a set. The simmerers were out of the package and appear looser than the old ones, although the dimensions scored on the sealers are the same as the old ones.
It requires reaming after installation. Perhaps it has to be that way because of the different dimension of the support tube and the changing dimension of the hole after the sleeve is pushed in.
