Just ordered 412's and the progressive fork springs. Wondering what fork oil you guys recomend.

Thanks

 

Amsoil seems to work pretty well - at least that's what was recommended by my indy who I trust.

 

Screaming Eagle Performance Fork Oil (Heavy) works great! I have the same combo (412's on the back and Progressive Springs on the front.)

 

right now it's 10w Bel Ray thinking of going up to 15w. good luck with your project.

 

Right now it's 15w Bel Ray. I'm thinking of going up to 20w. Yes, I'm being serious.

But my local metric shop carries the 15w so I'll probably stick with that for the duration. No complaints with it, but would like to try the 20w
