I have just got the manual abs at. I have done 500 km and notice a vibration at about 5000rpm. If you accelerate or shut off it goes away. If you hold speed in any gear at those revs it vibrates. All I have fitted is the center stand. Anyone had this problem?

Mine vibrates very gently from the idle all the way up , but i have never had a bike that does not vibrate at all :)

It's more the sound I'm hearing that worries me not the vibration itself. Never heard that on any of my other bikes.

I get this on my Honda CB500X. May be a common Honda engine problem. After 17,000 km hasn't caused any issues so I wouldn't worry about it.

The noise is there to tell you you shouldn't be revving it to 5000 rpm at only 500 kms. The noise will disappear when you have your first service. >:)

I also noticed it at part throttle , almost like a valve follower with too much clearance , im not too stressed about it ,( let it rev out or change up )

If you saw what they did to it in the factory:surprise: before sending it out you wouldn't be too worried about running at 5K RPM from the get go.

Do you seriously think every single engine is red-lined in the factory ? They pick a few engines at random and may test them to destruction, but they do not abuse any customer bikes coming off the end of the production line. All bikes are put through a full systems check, run it through the gears, but that's it. This myth of all engines being flogged when new is just that, a myth.

... I've seen it at multiple factories. multiple times. They bang it into fourth gear and either redline it or nearly redline it, before checking for baseline minimum power levels. And factories like Triumph do it on 'every' single bike.


In actual fact, when you're waiting for your new bike to be built, it's almost disturbing to watch knowing that your baby is going to get spanked before it's turned it's first mile!


But better to go kerplunk on the dyno, than in the outside lane at speed. It's no myth.


I can't comment on NVH, until I get my own. However, sometimes vibration (particularly numbing vibes on IL4's) can simply be caused through maintaining a too tight grip. As an analogy, I try to imagine that I'm holding a small bird in each hand. I'm gripping it sufficiently that the bird can neither fly away or be harmed. It probably isn't, but could be something as simple as that - give it a try.

I took bike to dealership today. They test drove it and heard the noise straight away. Between 4 to 6 thousand rpm. They even ran it on a dyno and recorded the noise. The guy agreed it was quiet loud. Later they called me and said it was normal. Bit disappointed cause the bike is really awesome. Anyway time will tell. I have done 600 km so it's run in.

Well I've been on factory visits to KTM and Ducati and saw nothing like what others claim.
Considering visitors don't get inside the test booth and have to watch it through the windows, I can only comment on what I've seen and was told by the tour guides. I'm sure they don't take it easy for the tours and then thrash them when us ordinary folk are out of the way.

I don't doubt what you are saying and I'm sure each factory has its own test methodology. But some do run them pretty hard, based on my own personal observations. to the best of my knowledge, it would be impossible to baseline a minimum acceptable power output without revving a bike into its upper rev range.


I hope it's nothing serious Ian. Hopefully a case of "they all sound like that sir"? It would be good to find another owner, whereby you can listen to your bikes side by side? Only way to be sure...

Yes I do! I spent 2 days at the Triumph Factory in Amarta City, Chonburi and every bike spends about 5-7 minutes in the test booth with much of that time at the redline, clutched and clutchless changes up and down the gearbox. I was shocked but it was confidence inspiring that they had no concerns in thrashing the engines, I pointed to the running in sticker on the tank and asked why is running in necessary given the manufacturing tolerances and custom matching of piston rings, valve shims, etc. to each individual engine? That answer was a wry smile from the engineer but more telling is that I was not given the bedding in parts answer.

I can only speculate that running in for modern engines today is more to do with safety and liability that any engineering reasons. It gives new riders (especially the less experienced ones) time to get used to the bike also if there are any manufacturing defects that got past testing they will manifest at low speed once again increasing safety and reducing liability.

All the more reason not to buy a Triumph made in Thailand then.
... I've owned six brand new modern Triumph's. I ran them all hard from new and totally ignored the running in procedure, other than being careful to bed in brakes, tyres and get the engine to normal running temperature before opening them up. The only problem I ever had was a flat battery on a Speed Triple. Maybe I killed it? Lots of my friends have bought Triumph's and they've all remained reliable, so I think they know what they're doing. Vive la difference though....

I drove a Triumph Tiger 800 for 85.500Km in 5 years, with several consecutive 800Km/day trips in Europe and Morocco. 80% road, 20% off road ... zero problems! Nun whatsoever.
I hope the DCT that will arrive in one month will give me exactly the same problems I received from the Triumph.
I will start with a 6.000Km trip in May or June. If I have any annoying problem, I sell it immediately with a 2.000€ discount, and go back to a Tiger 800 XCX.
Hope not, because the AT promises to be fantastic!

I have had a Transalp 600, an Africa Twin 750, A super Ténéré 750, 2 Yamaha TDM 850's, a TDM 900, a Super Ténéré 1200. And I must say, as a twin addict, this is far the smoothest bicilindre I have ever had. I wonder how they made this thing : without any enoying vibrations, it delivers the sensations of good thumps and punchy power. I prefer the beats of a twin over the flat character of a 4 or even a tri. On the other hand, every bicilinder suffers less or more those vibrations. Untill now, this is the first best of both worlds to my opinion. Hope the engine is a bit durable, but until know it is amazing to me !
