I have faced this in 4th gear at ~4000 rpm riding at about 40 km/hr.

Dude. Fourth gear at 4000 on 40? That's pretty classic. Try keeping it to 3rd at 40, that's kind of asking for it. It happened to me too at that rpm & speed, in 4th, but a Duke would have punished me for that with a jar for sure.

Well, may be the engine speed in this scenario seems slightly put of place, but it has happened in 5th gear and doing about 50-60 kmph as well.

I have had the stall issue only 4-5 times over 2500 kms. I think I have also subconciously found a way to avoid it but as others said this is not a classic mechanical stall issue (low revs vs high load). Seems to be some software issue which Triumph should be able to fix over time. Anyway, I dont think about it at all seeing the frequency with which it has happened to me is extremely low.

Edit: also a point to note that I almost never lug the engine. I maintain it above at least 3.5k-4k rpm on each gear, depending on my speed. If people like to lug the engine, the issue may be more prevalent for them.

The stalling issue occurs when the engine is near idling speeds when the clutch is pulled in, such as when you are going over speed bumps or filtering through traffic at signals. A recent ECU update tries to avoid this by revving the engine when it detects uneven strokes, which are when the engine might be stalling.

However, this doesn't work always and if the revs don't go up in time, the engine stalls suddenly.

This bike (any bike with a higher capacity engine) needs to be ridden like a 400cc power plant (which it is) not like a 100cc commuter. If this is ridden at 4000 rpms in 4th gear it is going to stall. It’s not the bikes fault, it’s the way it is ridden which is wrong. Please do not lug the engine like this, ride in a proper gear for the speed and this stalling issue should disappear. If it still happens then by all means go into analysis mode.

Got to know from one of the threads here at TBHP that Triumph is recalling Tiger 600 for the same engine stalling issue and clearly identified the problem in their communication with the customer.

Not sure whether something similar is happening with our Speed 400 as well.

It is possible but here I would also like to point out that this kind of issue is prevalent in quite a few recently launched vehicles. The new Himmy had the random stalling happening to Yammie Noob during the press ride, there were reports on the older dukes. Even the newer gen 3 dukes have the fuel gauge inaccuracy apparently.

I am seeing a trend where the stalling issue as well as the fuel gauge inaccuracy has been observed in the speed, the duke and the new himmy. I have a feeling it is on of the subcomponent suppliers (like Bosch, Minda, Denso etc) are not working as intended or are communicating properly with the ECU.

It could all be anecdotal too so I am not going to bet on it. Just an interesting thing I observed.

Examples mentioned above:

Could it be linked to the new fuel standards, blended fuels?

Just a suspicion I've been harbouring.

Hi all, just came across this news.

Triumph Speed 400 was launched with a discount of 10,000 for the first 10,000 customers. However, it has now been announced that the 10,000 discount has been extended up to 31st Dec 2023 regardless of the number of customers.

So in case you have booked it recently and the showroom said that you are late and are not in the first 10,000 customers, then you can speak to them and get the discount arranged.

Source : all major Indian automotive websites. You can Google it. The news came out just an hour back so thought I will share it here as this review page has plenty of active members and readers.

Swingarm broke into two.

I just saw this post on Facebook by a fellow Speed 400 rider.

This issue falls into the highest critical category. Not sure how a swing can break apart during a simple fall.

I am worried now. I completed the Adi Kailash ride in Uttrakhand in the last week of October this year and planning for White Spiti this winter.

This is a himalayan concern no doubt. Just learned of it elsewhere.

There is no evidence of a fall on the side shown in the photo. Something is fishy... Could be a stunt gone bad.

More details and photos will help us "determine" (speculate) on the cause.

Correction- It is Scrambler 400x and not Speed.

This motorcycle is just 560km old and the guy is using it in Manali. He own a motorcycle rental agency there. As per him, he was on well laid tarmac riding at 40kmph when the swing arm cracked.

No damage to the other parts as per the front left picture shared by him.

Important bit of info. It looked like the Scrambler in the earlier photo, but could not be sure.

Do the Speed and Scrambler share swingarms?

Cheers, Doc

It seems that both the models share this swingarm as technical specification on Triumph India website mention Twin-sided, cast aluminium alloy for both.
