Aprilia RS 660 YSS TDS Shock Absorber (20-25)
The new TDS (Track Day Shock) series of motorcycle shock absorbers from YSS have been developed with one thing in mind - to go as fast as possible around a circuit, whether you're a track day specialist or a racer.
Although YSS are fairly new to the track day/race market, bikes fitted with their products are already turning heads in many paddocks around the world, winning championships in Europe and New Zealand on the latest and greatest 1000cc superbikes and the smaller 400/250cc bikes. Considering that YSS are the the worlds largest aftermarket motorcycle shock absorber manufacturer and have been in the game for 40 years, it's no surprise that they appear to be getting it right first time with their latest range of shock absorbers.
Over and their standard MG456 and MU456 shock absorbers, aimed more at road biased bikes, the TDS series shocks benefit from the following...
- Redesigned seal head
- Modified spring/spring rates

- 30 clicks rebound adjustment
- Length adjustment (on most models)
