Speed Twin Cutting Out, Additional.

My SpeedMaster does the same. It was new last year and has just completed 600 miles so it’s going in soon for its first service. I suspect it’s the fuelling running very weak to get through emissions means that when the engine is hot and you come off idle to some throttle there might not be enough fuel to air mix to keep the engine running so it stalls. I’m hoping Triumph have an answer otherwise I’ll have to think of a remap as the times it has stalled has been in very dangerous circumstances.

I had this happen to me on my 2019 Speed Twin a few times now, clutch into change down to a junction or roundabout. Bike just cuts out. Restarts straight away but can fluster you when you are in traffic! I would say at least once on every ride this catches me out.

 

I've had a couple of different triumphs do this over the last lot of years. You'd have though they would have sorted the issue by now

Update
Recently had the bike serviced and was told the throttle bodies were out of cal/sync. Will see if this has fixed it.
