Tiger 900 Engine Vibration

[nickjaxe]

I must admit i do wonder about long term reliability of the 900 against the 800 , ive seen many 800's well over 100.000 and still running smooth as silk .
But i wonder if an engine as unbalanced as the 900 will make it that far ? ... only time will tell !

On the question of speedo inaccuracy my 2019 800 xca with the TFT is terrible at a registered 70mph im actually doing 63mph , so i run with my tomtom gps on all the time as it can be damn right dangerous on the motorway when your not doing the right speed .

If the tyre size is altered...it will effect the speedo.

Can the speedo be off by 7 percent and the odometer still be accurate ?
A taller front tire would no doubt lower the speedo reading if the front is the supplier of the info as back in the speedo cable days . With speed sensors on both tires now the info could could come from front or back , right .

Fortnine has an interesting take on triples:

Yeah, v4! Triples problems, but I’m cool with my twin. LoL. Nothing is as near perfect as a v4, I can dig that. Had a SAAB Sonett III with a v4, it was pretty cool for an old car. Interesting that it would be a good configuration for a motorcycle engine.

On standard tyre sizes 90/90/21 150/70/17 ... one thing i will say is its perfect at 30mph but as the speed increases so does the inaccuracy im not to bothered now ive got used to it , but i thought electronics were supposed to be better than the analog they replaced ???

What an interesting video.

It would appear there is no way to avoid some of the buzziness of a triple cylinder. That said the power delivery is intoxicating. My Speed Triple came with foam grips (now I know why), and riding it there is some vibration but I can tolerate that for the periods I'm on it. What's impressive is the power as you wind it up. The more revs the harder it pulls. I was riding with son-in-law a couple weeks ago and coming away from a stop sign I just started to crank up the revs in first gear. After about 6K the front wheel came up and I shut the fun off at about 9500.

Every bike has trade offs, one either embraces the pros and cons or gets rid of it. I don’t spend a lot of time on negatives other than figuring out if it’s me or not. If I can mitigate it, I will. If not I learn to live with it. Everyone has a different way to address these issues and different preferences.

Yes, the speedo can be off by 7% and odometer still be darn near spot on. This is assuming you are running stock tire sizes. The speedo error is deliberate. I assume to avoid lawsuits.

Bike speedometers tend to lean on the conservative side as do car/truck speedometers. Keeps the big corporations out of courts and avoids legal claims and the associated costs.

For long trips, i rely on my gps for correct speed. The variation is from 4mph to 7 mph depending on speed. The faster you ride, the greater the bikes display error.

From the Triumph web site:
A new firing order was incorporated for a more engaged Tiger riding experience giving up to 9% more power across the rev range and a high-overall-peak power of 94 HP @ 8,750 rpm, plus 10% more peak torque than the Tiger 800 predecessor. The Tiger 900’s new T-plane triple crank and new 1,3,2 firing order has improved the character, off-road feel and on road performance of the engine and gives a more aggressive and engaging T-plane triple soundtrack with a more distinctive triple bark.

You get the "soundtrack" and additional vibration at no extra charge!

Seriously, I really, really wanted a Tiger 900, but the new engine just has too much "character" for my liking. Maybe Triumph will tweak it in the future.

Ahhhhh, character. Character is what manufacturers call vibration while assuring you "they all do it".
The buzzy-ness/vibration (i.e. character) of seeming all of the new triples, has prevented me from considering them. I really wanted to like the Tiger 900, but a ride changed that. Same for the Trident and Tiger 660. I've owned Triumph triples since the mid 90s and my memory may be fading, but I don't recall the character of those engines being as pronounced.
This is not a dig at any of these bikes. Many folks love them, and the vibes don't bother them. I wish I was one of them.
It is interesting to me to note that Triumph appears to have addressed/acknowledged at least some of the vibration issues with the refreshed Tiger 900. I'm eager to try one once they are available.
