I think it might be the cush drive rubbers. Perhaps they've perished or worn away or fallen apart.
Years and years ago my tyre man forgot to put them back in and it it clonked each time I moved off . I didn't get far though.
If you think it's the chain just lift the back wheel off the ground (hammer under swing arm works) and spin the rear wheel. Look for tight spots on the chain and wobble on the sprockets front and back perhaps chain is loose and you're getting whip?
If it's not this then things only get more expensive and complex. ____________________ Spain 2008France 2007Big one 2009 We all die. The goal isn't to live forever, the goal is to create something that will. In the end, your life will flash before your eyes. Make sure it is worth watching. |

It needs a rear tyre, and also a service, so I guess it’s a good time to look into the issue. I’ll let you know if anything is found |

Gearbox in neutral, grab the rear sprocket and try and rotate it forwards and backwards. If there's significant free play (without the rear wheel moving), it's the cush drive rubbers.

My 250 had less than 20k on it and the cush rubbers were worn...then again it was a thumper (single) and an old one at that.
[rummages through service pdfs]
For my current bikes it doesn't give an interval when to change the cush rubbers, just check for excessive play and replace if necessary.
I changed the cush rubbers on the 944 twin at 35k. ____________________ Diabolical homemade music Bandcamp and Soundcloud

Cush drive rubbers were worn on my Brutale when I got it, with lash that went away after replacement; 2012 model with 7.5k miles, bought mid 2017. On 12.5k miles now and still good.
Thankfully it uses the wedge-type rubbers rather than the rubber-covered spacer version used on other MV and Ducati models. Difference between 20 quid and 120 quid.
Wouldn't be surprised if they wear out on a bike that isn't used and parked with them under pressure (e.g. in gear with chain under tension). A bike that likes to accelerate hard probably suffers too. ____________________ Bikes: S1000R, SH350; Exes: Vity 125, PS125, YBR125, ER6f, VFR800, Brutale 920, CB600F, SH300x4
