Does anyone know if OSFO10-10wt fork oil is the correct oil for a 2005 Ducati monster 620? Race-tech's website says to use 10 wt and I couldn't find anything to verify that. My friend is going to re spring my forks this weekend for me while I am out of town and the only thing I have left to get is the fork oil. I think I am going to go with the Bel Ray 10 wt, unless anyone has some better suggestions.
Thank You
7.5W correct weight
Thanks dark monster 620! What brands do you recommend? 2 quarts she be enough ?
What springs are going in?
RT FRK SPR 38.2x36x273 .90kg (Race tech fork springs)
yup, same as mine, 7.5W or ATF . . . with one quart you should be OK, any brand you prefer . . .
From M620 manual:
Recommended oil:
SHELL Advance Fork 7.5 or DONAX TA
Standard capacity:0.480 cu. dm each leg
Standard oil level:104 mm
Oil quantity affects fork behaviour when at the end of the compression stroke.
High oil level increases compression loading, low oil level will lessen it.

Oil level is measured with forks fully compressed, no springs.
The OEM oil level is quite high, somewhat in combination with the dodgy OEM springs.
With those springs, I'd say start with 10wt at 120mm.
BTW, how much do you weigh?
I am 250lbs
Are you still running the OEM rear shock and spring?
tell us that AT LEAST you have it dialed up to max hard
I am still running stock shock and spring. I dropped my bike off today to have the front fork springs I mentioned earlier put in, as well as the rear spring I got from race tech for my weight. I did not do anything to the suspension prior to this.
I'm pretty sure what the kidz are saying is...
at your weight, you'd like your monster more if you also upgraded the rear suspension, as well as the front.

Mmmm... which shock spring did you get?
Was it Racetech's recommendation or.....?
Yes race techs recommendation and race techs spring. RT SK SPR 58.2x178 10.7kg-105N
Just got her back my buddy brought it into work so I get to drive her home :) can't wait !!
I see the RaceTech rear spring calculator is still FUBAR.
I'm running a 10.7 spring on my M750, and I'm 175 lbs in street clothes.
I think you'll be happier with something like an Ohlins 12.2kg-120N, which would be a 1092-44/120.
Soft side option would be the RT SK SPR 58.2x178 11.6kg or Eibach 0700.225.0650.
Hard side option would be Eibach 0700.225.0700.
I will write that down for the future. Since I just got this done and I am experiencing a world of difference, I will enjoy it for a while! Thanks again to everyone who helped me out and all the information!
