what torque specs do you suggest for the top yoke clamp and the lower triple tree clamp? The Ohlins instructions say, '20 Nm for the top yoke clamps. 10 Nm for the lower clamps.' One thing, it makes no sense to trque the uppers tighter than the lowers and another thing, 10 Nm is only about 7 ft lbs.

I bought my FGRT 807s second hand from a guy who purchased form you.
Could you help me out with torque specs for the top yoke clamp and the lower
triple tree clamp? The Ohlins instructions say:
"Tighten the fork crowns with the following torque: Upper fork crown 20
Nm and lower fork crown 10 Nm."
That doesn't seem right to me. 15 ft lbs on top and only 7 ft lbs
bottom??? Can't be right.
Thanks,
Oh, This is a 2008 Kawasaki ZX-14 the forks were installed to.

These torque number are correct for the FGRT807 as well as its replacement
the FGRT207
Those are the numbers I would recommend

Well, I'll be damned. Four bolts on the lower fork clamps 7 ft lbs each one! I might go a pound or two tighter. Don't think I'll be doing any wheelies right away.
I also emailed Ohlins to verify the torque of the fork clamps. SHEESH, 7 ft lbs!
Here's what they had to say:
Comments: What are the recommended fork clamp torque specs for FGRT-807 forks on a 2008 Kawasaki ZX-14? The spec in the installation book for the lower clamp is 10 Nm. The spec for OEM lower fork clamp is 30 Nm.
Hello Daron. Thank you for your email.
Always follow the Öhlins fork manual mounting instructions including torque spec recommendations. The stock OEM forks are a different design and have their own torque specifications.
Thank you, Jerry
