YSS Shock Absorbers - Warning - Danger to Life

[krbkk]

YSS shock absorbers for Harley Davidson Softail, HD part no. 54508-00, YSS part no. RT306-220T-02
have a design or manufacturing defect.
The connection between the shock absorber and the mounting point is too weak.
After only 10,000 km, the eyelet is so bent that the high-strength threaded bolt is breaking off, or at risk of breaking off.
If the second bolt also breaks after just a few km, an accident is inevitable, and could even be fatal.
If you have installed such a YSS shock absorber, check it and replace it with a different brand if necessary.

How much do you weigh?

So you have a broken mounting bolt ?
The shock wasn't bent until the bolt broke.

However, I'd reach out to them and let them know. They may be seeing a pattern.

Where you bought it, and who installed it? 

 

Sounds fishy, and you sure it was installed correctly and with original parts?

 

Have you checked if there is a  common problem?

How do we know the bolt is high-strength and what does that mean? 

Maybe the bolt is a stock Harley bolt it probably, certainly isn't a YSS bolt.

You broke a bolt and thought the best action was to slander the company....

The owner of YSS is highly litigious as well...
