Best known for their scooter shocks, YSS has quietly been making in-roads on the performance market. Some years ago the Thai company hired expertise from Europe with many years of experience developing shocks for White Power, Technoflex & Wilburs. Today YSS is making small runs of high performance shocks for the Big Four special performance bikes. I have been fortunate that YSS Thailand used their skills on adapting a shock setup for the Scrambler using my bike as a guinea-pig. Here are the technical details: Rear Shocks Rear fitting of G 366 TRC shocks with correct spring , tailor-made rebound and compression settings. Installed with correct static sag adjustments. Length was extended 30 mm from standard shock . Aussie dealers undergoing YSS training fit my rear shocks I now have 126 mm stroke , compared to 100 standard of the G366TRC. YSS will soon be offering this special Scrambler YSS version through their distributors. Front Forks Front fork : Use standard spring, modify damping rod and install PD Fork valve 310. 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 http://www.yss.co.th/pd_fork_detail.php Materials 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. Quality Control 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 Thruxton 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. Distributors Here in Thailand YSS have many outlets - al,st every major urban centre. See here for their website www.yss.co.th In the USA please use http://www.yssusa.com The importer's name is Klaus Huenecke. In the UK / European distributor thru www.yss-europe.com In Oz - Link are the distributors and in NZ call Jason @ Thunderbikes. Other Bikes They do make shocks for other big bikes. Africa Twins & BMW R100GS are two that member have asked about. They are about to bring out shocks fore & aft for the R1200GS. There will be many more -TDMs etc- but you will have contact them. 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.
