Note they removed my progressive springs I had installed
and reverted to OE with this new fork valve.
Walter Preisig [ex White Power] & Aussie dealers rebuild my front forks
Oil weight was 15 W and air chamber for internal use.
Set Oil height and spring preload to carry specific weight.
In my case - substantial!!
See here for front fork setup
All aluminium parts are made of 6000 and 7000 series and are hard anodized.
Shafts are C45 and induction hardened, and hard chromed.
Piston ring and guides are made of calibrated Teflon.
This manufacturing process in line with QS9000 & ISO 9002,
German TUV approved and on even parity with the quality of Ohlins or WP.
Since the inclusion of suspension experts from Technoflex,
Wilburs & White Power YSS have gained ISO & TUV ratings.
Quality control for them is paramount even down to DVD
cameras recording the build of each shock
- so they can bactrack to construction should there be a problem.
For the Bonneville
YSS suggest the Z366TR or go with the G366TR for what they call “more extreme use”.
Which they mean by Offroad , Heavy luggage etc
Similarly for the Thruxton they say for normal street use the E 302 the
Z302 and the G302TRC could do the job.
Depending on your budget and need for adjustability.

Finally this setup has given me 26mm additional travel
but more importantly firmed up the riding package
and actually making the bike handle both on and off tarmac.
YSS is not just a cost effective option but it also matches the quality
of its more famous European competitors.
