Daytona 660

Maybe the flashing tacho is a UK-only thing. I had a chat to the main man at Youles about it and he said the flashing moves further up the rev range through the running-in period until at 1000 miles it reaches the redline. Apparently it can be switched off but no-one had told me that.
I'm happy with the brakes so far but maybe I've not been going fast enough yet to really test them.

 

Evotech tail-tidy fitted. If you look closely you can also see the essential new rear brake fluid reservoir.

I'll be interested to see if any other manufacturers at the Birmingham show have produced parts for the bike. I want shorty brake and clutch levers and maybe a pillion seat cover. I don't like the one from Pyramid and the ridiculously expensive OE one from Triumph (£280??) isn't even colour coordinated, it only comes in shiny or matt black.
I shall see what's out there in November.

 

This has already been mentioned elsewhere but I think it's worth repeating it here because, after all, this thread is called Daytona 660.
Triumph have issued a recall for all of these bikes. I've had a letter from Triumph saying it should be taken to a main dealer asap, so that the dipstick can be replaced with one showing a different oil level. It seems the engine requires a bit more oil than is stated in the manual. Failure to do this could lead to oil starvation and consequently serious engine damage.

 

Here's a bit more detail about the recall.

Triumph received the first warranty claim on 17/7/24. In total there have been 13 complaints from owners and 18 warranty claims.
The decision to recall all bikes was made on 12/8/25.

So far there are no recorded accidents relating to engine failure.

Triumph say that in controlled testing the defect was consistently reproduced. When oil levels were increased the issue was fully mitigated and engine performance remained stable.

So what do people think?

It took them a year between getting the first claim and recalling bikes. Quite a long time. How many more bikes were affected during that period?
There's no indication of what happened that made owners go back to Triumph. I would like to know what the 'symptoms' are.

They also say: 'The engine may degrade prematurely due to internal damage. In extreme cases this could increase the risk of a crash, especially during high-demand riding conditions eg. aggressive deceleration'. They talk about insufficient lubrication within the crankshaft bearing.

Worryingly they add that there are 'No warnings' that this is going to occur.

The 660 engine is used in other bikes including the Trident and one variation of the Tiger but there is no mention of either. The Daytona engine is in a higher state of tune, so maybe that exacerbates the problem.

As a Daytona owner here's what I feel...
Disappointment that this serious defect wasn't picked up during the development and testing stage. It should have been.
Concern that it took almost a year to issue a recall. If there is 'no warning' and an 'increased risk of a crash' surely Triumph should have worked their bollocks off to get the testing and recall out there asap.
Is my bike affected in any way and if it is how will this affect engine longevity as the miles clock up?

I have some peace of mind in that Youles have a lifetime warranty on engines (and gearboxes) of new bikes bought and serviced by them. I don't know if this is standard practice across all dealers. So if mine blows up after the recall work I'm still covered (hopefully I won't be injured or killed).

I will be discussing much of this with the Youles manager when I (very slowly) take my bike in. But from past experience I don't expect to get many answers.

 

My bike is booked in for the recall work next Tuesday. The chap on the desk had to think very hard to remember that there is a recall on the Daytona. He thought it had something to do with a 'faulty dipstick'. When I explained that it concerned potential oil starvation, engine damage, increased risk of an accident, all without warning, he assumed I'd been trawling social media sites and told me not to believe everything I read.
So I've printed off a copy of the US. Dept of Transportation Safety Recall Report, which shows all the details I've already mentioned and I'll take it with me on Tuesday.

 

Took my bike in yesterday and had a chat with their chief mechanic..sorry, technician. He didn't know a lot about the recall, other than the work that had to be done. I showed him the US report. He reckoned that the 18 warranty claims were most likely from racing or track day types, where the bike is used to its max. That sounds feasible.
He also thought that possibly the Trident had a deeper sump and a touch more oil, meaning it isn't likely to suffer the same fate.
Having been reassured by the 'for life' warranty on the engine and gearbox, plus one cup of coffee later, I was back on the road. Happy days (as Henry would say).

 

That is annoying to say the least, firstly that they seem unaware of the problem, which I find difficult to believe. Secondly, they don't even have the replacement oil filler dipstick available.
If you're at all concerned then you could always top your oil up while you wait for the part. I think it needs around 250ml extra, which isn't a lot. Alternatively just take it easy on the bike.

 

Triumph make a pillion seat cover for the 660. Actually it doesn't cover the rear seat, it replaces it. But it costs an unbelievable £225 !
They also say it's colour coordinated. It's black and only black. My bike is red. And the Daytona also comes in white. Very strange
So my plan was to buy a non-Triumph cover and have it painted red. I found a few online and was about to take a risk on one from Wolfline (nope, nor had I) at around £50 and hope it fit. But fate stepped in and up popped a genuine but used, Triumph seat cover (in black of course) on ebay. A brief haggle and it was mine for £90.
I took it to my local painter, sprayer, whatever, together with a part of the fairing so he could match the colour..



That's the pic he sent. I'll whizz up there on the bike in the next day or two and fit a 'proper' colour coordinated pillion seat cover

 

After clearing the road outside my gate of rotting leaves and accumulated muck (using a hose) I took the bike up to R&R and collected the pillion cover.





I think I made the right choice in having it painted, it looks much better.

 

Thanks Joe. Dunno why Triumph don't make it as an option.

 

Had mine since April this year, also from Youles, and other than the recall issue I've not experienced any problems at all.

I don't really think you can complain about the dipstick recall. The (likely) reason for it is discussed a bit further back in this thread. If you've stuck to the running in procedure then I very much doubt your engine will have suffered. Recalls happen. Fortunately Triumph are sorting it. As you say, Youles have a lifetime warranty on the engine, so you're covered if it ever goes pop.

As for your other issues it does seem very strange that a bolt has been sawn off and glued back on. What did Youles say about this?

I've not heard of anyone else having quickshifter problems and I know it's a pain having to trek to north Manchester, especially if you're brave enough to try and get through the city. You've obviously been unlucky. Similarly with the indicators.

I would be very tempted to ask for some sort of discount on accessories or Triumph gear, as a goodwill gesture for the time you've had to spend having these things dealt with. I managed to haggle a free frame protector kit, plus a discount on other parts when I bought mine. They want to keep their customers happy, so give it a go.

 

Hopefully that will be your problems over and you can get on with riding it instead of worrying about it.
I would still be interested to know what Youles thought about that wayward bolt.
