Anyone know Ohlins?

[Phenix_Rider]

I found a private seller on another board selling a rear shock for the 650R. Sprung for (close enough) my weight even. Seriously thinking about grabbing it. Preload-Compression-Rebound damping with a separate reservoir.

Can't find any information except that the shock body says Ohlins Racing 629, and the spring says 1093-79/190 L167. Tried searching Ohlins site, but all I cna find is their recommendation of a single adjustment shock Part no: KA 602
Type: S46DR1.

The warning on ohlins site has me a little concerned...

Look out for fake steering dampers! During the last couple of months Öhlins Racing have been contacted by several buyers of fake Öhlins steering dampers – often bought via E-bay and such. Be sure to demand full documentation before you purchase any Öhlins product through the Internet.
