Spring/Fork Oil for fully loaded RTW trip

Hey all,

So I've dialed in that I need to replace steering bearings and fork seals.

While I'm at it, I'm thinking of changing out the stock springs, because I'm fully loaded with all my gear.

Opinions on if this is worth the money?

I weigh 175, and my gear probably weighs another 120.

I do about 85% road, 15% dirt

Any info would be appreciated!

Pete

Here's Sonic Spring's spring calculator.

You may want to contact them as well considering your gear.

So I bought a 10W fork oil, but they sent me a 15 w instead. Is this going to be too high viscosity? I ordered the .90 kg/mm springs

Thanks!

The true viscosity of fork oils vary wildly between brands regardless of the “weight” advertised. There’s a chart floating around somewhere (ADVRIDER maybe?) that shows the tested viscosity of several common brand 10wt fork oils. So, it’s tough to say exactly what you have and it’s effects on the fork damping. I’d say if it’s the one recommended to you by a reputable suspension shop to go with the springs you ordered, you’re probably fine.

Fork oil weights
I have Bel Ray 15W fork oil. Might be tight, but it is a lot of weight on the motorcycle. I'm gonna try it out and worst case just replace it after a few thousand miles

Thanks for the chart!

I'm 178 in my birthday suit. The .90 springs are heavy enough for me, with a 600 lb. in the rear. The spring changes are slightly too much unloaded, & not quite enough for a load. So, best happy medium for me.
