Since its establishment in 1983, YSS has become renowned for its use of high quality components and cutting edge technology. Every part that goes into a YSS shock is designed, manufactured and tested in house at the YSS factory in Thailand. YSS has achieved TUV, KBA and ISO accreditation for its consistency in producing innovative and excellent products, and as a testament to this the entire range comes with a full two-year warranty.

Engineered to the ideal specification for each bike, YSS shocks come ready to install straight out of the box, without the need for further adjustments.

A strict testing process is used at the YSS factory to check that the shocks meet OE fitment specifications, with each one being specially heat treated for extra durability and strength.
