I can honestly say I'm still pleased with it after I've put over 1,500 miles on it. It has a pleasing lumpy idle - sounds like it's cammed.
Takes a bit getting used to the right pull from the transverse engine torque - quirky but cool.
The power is definitely there. I have no problem getting speed even from lower RPMs. It's not a crotch rocket but you won't lose to a Harley either
It doesn't seem to struggle even around 95mph as indicated. Wind is more of an issue than power at those speeds. One thing I love is it is stable in winds. I have to do a couple of flyovers on 183 and gusts don't budge this thing. Not once have I felt like I had a handful - a very tractable beast she is. I suspect that's a result of being "naked" without all the fairing junk. I have a café style Marlin screen on it right now which all but eliminates head bobble in head on winds but I think for longer distances at freeway speeds a larger screen is called for. The exhaust has a pleasing grumble and positively bellows when you get on it which is a surprise given the E5 rating involves noise levels as well as emissions.
I thought perhaps those massive jugs right next to my legs would be hot but I never noticed even on 95+ days.
Mine has shown no ill manners except for a reluctance to start when it got down to 60 last week. The tech at AF1 gave me a couple of tips so I'm going to try them tomorrow morning since it's supposed to be colder than that. I do need to let it idle a bit before taking off or it tries to stall unless you really feather the clutch.
In summary I'm 98% pleased with it.
{* UPDATE *) I started it no issue this morning at 49F. She must have just been feeling grumpy that day
My only niggle is a small one that may get fixed with a ECU flash.
Cruising around 3200 RPM sometimes it will act like it loses power for a very brief instance - almost like the bike "pauses". Very odd and the tech says he's reported 5 instances to Moto Guzzi. I also mentioned that it seems to run a tad rough around 3800 rpm. His theory is that both items are a result of the ECU transitioning from closed loop to open loop in the ECU. That makes sense and is something they can fix in a better tune to flash the ECU with. How long that will take is big guess but it doesn't bother me sufficiently to stress over.
The bike is odd in that there seems to be a lot of vibration but it's not objectionable. My VStrom buzzed my hands to where they'd get numb. I've been on a couple of 200+ mile trips with the MG and not had any effects from the vibration. Must be in my head
The seat is also very comfy but I pushed it once to 200 miles without a break and my butt wasn't happy - but nothing debilitating. The Centenario has a leather seat which is a bit firmer than most seats I've had.
Easily already in the top 10 of bikes I've owned and the first I've found nothing of importance to complain about after the honeymoon is over.
