davlec Posted December 7, 2018 Share Posted December 7, 2018 I'm about to install a YA535 on my 2015 and would like to get an idea of how effective the hydraulic preload is with the standard spring. I'm 85kg with gear. A pillion and luggage adds about 100kgs. Will the hydraulic preload compensate fully for that load. I'd like to hear from people with actual experience using the YA535 with a load if possible. Link to comment Share on other sites More sharing options...
Supporting Member betoney Posted December 7, 2018 Supporting Member Share Posted December 7, 2018 Did you already order the shock? Usually when you buy a shock the first thing they want to know is what you weigh with riding gear and they sell you the correct spring for your intended use. Spring rates are based on weight, I dont think there is a "standard spring". ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
Premium Member coachluciano Posted December 8, 2018 Premium Member Share Posted December 8, 2018 I just installed one last weekend. I weigh 180lbs without beer. I’ll shoot you the spring number the factory sent me if you want. I did tell them my weight. Sag comes in about spot on with little to no preload with provided spring. I have also read those who ride two up with this shock just have to give the preload a couple rotations and they are good to go. That is one of the big benefits of this shock.

I have emailed Ohlins Australia regarding this but they haven't bothered to reply. Suppliers overseas haven't answered either. I would like to know what spring you were supplied with. If you have a YA535 would you be able to get someone weighing about your weight or more on the pillion seat to get an idea of whether or not the hydraulic preload can bring the sag back up to the solo measurement.

Supporting Member texscottyd Posted December 13, 2018 Supporting Member Share Posted December 13, 2018 @davlec - I’ll take a look this evening and see what spring was provided on my YA535. I’m about 225 pounds, and had it ordered for my weight and riding style. Not sure of the rate / spring number they fitted, but it’s spot on for me.

kemmotar Posted January 5, 2019 Share Posted January 5, 2019 the standard spring is 95Nm. its ok for a rider that weights 80 - 85 max kg naked. you should add aprox. 10 kg more for proper riding gear .... i have a 100 Nm rear for my 535 and its on stiff side but i have a bit longer rear wheel so i run with preload at 4 or 5... for proper sag values...

My apologies, but I don’t have an answer for that yet... I didn’t see any part number or spring rate markings on the spring, and I forgot to check the box & paperwork. I’m traveling for a couple of days, but will check when I get home later in the week. -Scott Link to comment Share on other sites More sharing options...
Supporting Member texscottyd Posted April 10, 2019 Supporting Member Share Posted April 10, 2019 While we’re on the subject: Is there a marking or code on the spring of my Ohlins YA535 that I should be looking for to determine the spring rate? I took a quick look and didn’t see anything obvious, but I’m not sure where I should have been looking. Link to comment Share on other sites More sharing options...

I took a quick look and didn’t see anything obvious, but I’m not sure where I should have been looking. The information code should be printed on the spring- First code(4 digits) = length Second code ( IE: 29/90) that's Ohlins code for stiffness ( Ohlins says code 29 is 90nm) Third code is batch number... Here is the stiffness code chart: 2012 wr250f - C-class 30+ age group 2015 fz-07- Hordpower Edition-80whp 2015 fj-09- Graves Exhaust w/Woolich tune by 2WDW @120whp Link to comment Share on other sites More sharing options...
Supporting Member texscottyd Posted April 20, 2019 Supporting Member Share Posted April 20, 2019 Ok - I finally found the Ohlins spring code (mostly) on my YA535. The portion I can read says ‘36/105 L0317’. There might be something that precedes it (the spring length, based on @norcal616‘s information), but I can’t see that with the shock on the bike. Regardless, it appears that the 36/105 indicates a 105 N/mm (600 lbs/in) spring rate. I’m 225 pounds without gear, and it works perfectly for me.
