Advertised as YSS hybrid rear shock absorber, made to suit the Hunter Cub series.
● Features a newly developed twin-tube system with nitrogen gas and oil.
● Provides a stable and smooth ride.
● The upper mounting section is CNC machined and the lower section is made of steel.
● Features a dial mechanism that allows for hand-turned preload adjustment.
● Allows for 7-stage preload adjustment.
● They're made well, at least as I can see from their outside.
● Two 'YSS' stickers and preload adjustment tool included, though a stout plus driver suits fine to adjust as well.
● Just over ¥11,000 delivered.

It's an easy one hour job to fit, and you need to remove both air-intake snorkel and muffler to allow clear access to top mounting bolts.
Recognizing the Hunter Cub doesn't have a very sophisticated suspension configuration, there's only so much expectation as to the result. However, the change to these YSS resulted in a measurably smoother ride.
As well as for low-speed trail work, where the attack curve of a sharp bump is obviously smoothed, and rounded out.
At speed too, pavement bumps that previously jolted me, are now a slightly more leisurely float.
Noting perhaps, an initial short ride suggested I could not feel any difference and it was only when I went on a longer ride and went over some familiar bumps and other rough patches, that I noticed a real difference.
I am comparing both OEM and YSS set on their softest spring preload setting.

The only point to note perhaps is the recommended tightening sequence for reinstalling the muffler bolts - as above - 1, 2, 3, then 4.

I chose the black springs, instead of lairy red, and installed the 'YSS' label on the inside to tone down the modded look.
For the price, its an easy recommendation...
