Hey guys, I have a 2020 street triple 765rs and have had the engine cut out three times now. The first time was scary as I was in a round about and the other times was when i was in a eighty zone. I'm thinking if I take it to the dealer , they're not going to find anything , but I will get it checked as it's getting dangerous now. Has anyone had this issue.

I had this once slowing down to park the bike on a slight downhill road.
Mine is a 2020 RS as well.
I was positive I had not done anything wrong.

I was going to see if it happened again, but haven’t been riding much due to the lock down.

I ask, because a lot of us have seen issues with the 2020 quickshifter... Where occasionally it simply doesn't work... it won't click and grab the next gear. Stands to reason that if some have an intermittent issue where they fail to cut spark... others might "stick" and cut the spark long enough to stall it?

2019 RS here. I’ve had it cut out 4 times over 3,500 miles. Has happened 2 times coming off high throttle and 2 times with clutch pulled in at slow speed. Seems to happen when slowing down. Dealer checked it out for a few hours found nothing. Noticed some sulfation on the battery terminals so swapped out for a Shorai. I tried to make it stall in a parking lot in gears 1-3 and she won’t stall even with no throttle at a crawl so don’t think it’s fueling. Might need to check the charging system next but hoping they already checked that and maybe the quickshifter. One more year under warranty so hopefully can figure this out or selling her if it continues.

Yeah I’ve experienced this on both models of the new RS range. 2017 and new 2020 model. Usually 2nd gear clutch fully in, coasting.

Mu clutch assembly has been replaced on both models. (My new 2020 model has already hada full clutch assembly replacement -2000 miles - and now it’s happening again -3300 miles - Partial engagement but revs high and delivers no power. It will fail fully again and just Rev with no gear engagement.

anyboy else with similar issues?

I also have a 2020 765rs and I have also had the exact same event occur, three times over the last 3200km. In each case it was at low speed in either 1st or 2nd gear after shifting using the clutch. I spoke to my dealer and they had not heard of this issue. I will be taking it in shortly when I replace the tires, my dealer is 120km away. I am wondering whether it could be a faulty side stand switch.

Yeah it’s a little bemusing when it happens. Just cuts out without warning. Defo seems like an intervention as it just cuts the engine, dash is unaffected power wise.


I’ve had a few Issues with my RS’s from short wires on looms round the yolk, to clutch assembly’s going. I don’t not think it’s too out of line with other manufacturers..... And Triumph have always sorted it.....

Seems like we have two threads discussing the exact same issue.

I was out Friday and mine cut out without warning. It's a 2020 with 500 miles on it when it happened. I'm running it in by the book so wasn't going at any speed. I was either going from second to third or fourth to third. I pulled the clutch, kicked the gear in to third and it died. Scared the crap out of me as I was on a back road and had to coast to a stop on an unsafe stretch. The dash stayed illuminated and I just held the clutch in and rolled to a stop (not sure what I should've done?) Called the dealer and had to add another 80 miles to my 120 mile jaunt so they could run the diagnostic. Nothing found and they told me not to worry about it - "we don't have any known issues with the new RS".

Thinking I've made a mistake with this bike:
  1. The front end - headlight assembly is wonky - points left.
  2. This cut out worries me - clearly I'm not the only one with an issue
  3. When I got home the reflector above the numberplate had gone - fallen off somewhere.
  4. Checked the coolant this morning and it's dropped below minimum
I'm beginning to think that the spiel about Triumphs attention to detail is just bollocks

Mine cut out as I was nearing an exit. I just reached 500 miles accelerated then slowed a bit then I think I down shifted it cut out . hit the start button and nothing. thank goodness nobody was talking me.
It was scary I was riding all day like 150 miles because I'm breaking her in and wanted to get to 500 for the first service.
Also, I've had it stall on take off then hit the start button and nothing.

Hey guys , there is a guy on YouTube who filmed his cutting out exactly like mine. Look up 2020 triumph street triple 765rs , filmed by funny motoman and at 11mins 30sec the first cut out happens, then 11mins 58sec the second will also cut out. With his bike they replaced ecu, crank case sensor, but the culprit was the stator. This is of great concern to all who own these bikes .
 
#21 ·
Thanks for the info, it may be caused by a faulty pickup coil which is part of the stator assembly. The problem is it is difficult to diagnose because it happens so randomly. I think I counted about 10 times in 4000 miles and I may have gone 1000 miles without a stall. And it would start up for me right away. If I could get it to stall and then not start it would be easier to see the pickup coil is not putting out any voltage.

I'm wondering if I had this happen the other day with mine.

I was slowing down in 6th gear for a stop sign or something out in the country. I saw the oil light come on and my heart sank (I had just had the crankcase gasket replaced because it was leaking). I pulled off the road and that's when I noticed the engine was dead. It started right up and has been fine since. I just figured I slowed down too much in 6th, but now I'm wondering. The bike had ~2,100 miles (3380 km) on it when it happened.

Not sure if this is applicable, but I noticed when it was "cold" outside (40-50F / 4-10C) and the bike has sat long enough to be truly cold, I have to be careful with the throttle or it'll almost stall until the temperature gauge has got 3 or so bars.

It makes me think there's something with the fueling. Maybe due to EURO5?

I have 3000km. It has already happened 5 times. Last time was when shifting from 4th to 5th gear and it was quite scary because the rear wheel blocked in high speed. I am taking the bike to the dealer to ask for a new one, because this issue is very dangerous and can ends with a terrible crash

Fyi , I had a rep from triumph Australia ring me today as I had sent them an email in regards to the stalling issue. The conversation didn't start to well as he said the stalling problem was only on the earlier models , and I told him well it's happening on the 2020, and I've nearly been rear ended a couple of times and finding it dangerous to ride. The rep told to take the bike in to a dealership and get them to connect the bike to the computer and to then send all information to him so he can see what shows up, as he thinks he knows more than the trained mechanics there. So, the bike will go in to the dealership in the next two weeks as the brake pads for recall should be in by then as well and will see what they find. I'm being persistent on this issue , because others are starting to find they are having the same problem and someone could get seriously hurt. I suggest that anyone having a problem , email triumph and let them know .

It also had the problem... When I come of gears with clutch... Without (using the blipper) never have a problem...

Also had a problem with normal use on the quickshifter to go from 5 to 6...

Did a track day this weekend and had 0 problems, using the up/down shift, perfect en completly buttersmooth!

And believe me, I ripped the horns of this beast! :p

That is a pretty wear pattern, what psi are you using? I have a track day on Thursday, I normally run 28 front and 27 back using Bridgestone S22 tires. Mine are nearly at the end of their lives so I think I will go down to 26 or even 25 at the rear on Thursday but would be interested to see what pressure you are using.

Had my second stall.
Just over 4,000km on the bike now.
It happened in exactly the same place as the first one, finishing commute to work, on a downhill road, clutch in as heading into the bike park in second gear, engine died.

I did think the fueling felt a little off on that particular ride to work. On deceleration there was more engine braking than normal. I may have been imagining that, but I am going to pay more attention to it today.

Mine was serviced Tuesday and the dealer had spoken to Triumph regarding the cutout/stall for me before I arrived. They told him they were aware that some 2020 Street Triples were experiencing this problem and were working on a fix that was imminent. Something to do with fuel being injected on overrun.

Good to know my bike is booked for the 28th for service and recall on brake pads . The information on the ecu will go to some triumph specialist to see if anything shows. The triumph rep got a bit angry when I told him the bike is stalling , but stuff him , bloody wanker.

I left my bike at my dealer in Prague last week. They were very arogant, told me that they had never heard about this problem before. They were not able to solve the problem and they reported it to the factory. Told me that it will be neccesary to send the bike to England, but no detail information were provided. So we agreed on contract canceling, so they give me money back and I will leave them the bike
