So yesterday I was out for a ride on my 2020 V85TT ~23000 miles. As I was riding for some reason, maybe just giving the arm a rest I had my left arm hanging down by the front sub-frame mount. For some reason I grabbed where the sub-frame mounts and felt that it was moving. Not a lot but I could feel it. I had the cruise on and checked the right side and no movement.

I pulled into a gas station to check to see what was up. The Allen head was in place. I had so Allen wrenches so I tried to tighten the bolt. It was tight in both directions and wouldn't move. Road it home and pulled the bolt and you could see on the face of the head that it had wear marks. I believe the bolt was bottomed out, I also think that the hole is not threaded thru and thru.

I put a washer on the bolt as a spacer and the bolt tightened full and the sub-frame stopped moving.

Kind of a weird thing but thought I would give those with V85TT's a heads up to check for the sub-frame movement.

Guys. Please. Search before starting a new thread. The one below is where it goes. I'll combine it soon.

Thread 'V85TT issues and Loose Bits'

It might just be my V85TT but it's worth checking your sump guard bolts. While cleaning the bike this morning after yesterdays 220 mile ride I noticed that the front of the sump guard was loose. The front two M8 x 16 bolts that secure the black steel bracket to the sump were missing. The remaining two bolts that hold the rear bracket to the sump were barely tight, I could undo them with my fingers.

Page 204 in the service manual shows the assembly and torque figures of 20NM for these bolts. I can only assume they weren't properly tightened at the factory. It hasn't had its first service...
