Noob, Street Triple Question

[Tracer1234]

This is about as newbie as it gets. I have a 09 Street Triple. Love it, everything is great. Now, I have noticed it makes distinctive whining noise.

Two questions, one, what is it that makes this noise and two is it a negative thing that may get worse?

Surely you mean a "winning" noise? .

Means the engines toast along with the frame. The bike's scrap now. I'll give you £100 for it and you're lucky I'm not billing you for it.

Tried looking on YouTube for videos of STs running and seeing if it sounds like yours?

It's the distinctive triple 'whirr' I'll guess. They all do that, sir.

Whining how? Like when you go in reverse in a car? That's your engine telling you: ,,Stop being paranoid!''

Let me guess, it came with the factory exhaust system, which only means the noise from the engine itself is louder than the exhaust system. Buy an open exhaust system and I guarantee there will be no more whining from the engine, well you won't hear it.

You would not believe how loudly most of the Honda engines whine at idle and low revs, even with open exhaust systems.

And I could go on,

Triples make a superb whizzing noise.

All I hear from mine is 'Ride me like a whore, big boy'.

Mine makes all sorts of noises, whines, rattles and so on. But it also sounds awesome. Buy a loud exhaust and forget it.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Its because Triumph used straight cut gears to run the balance shaft rather than a helical gear set.

Perfectly normal.
