Yes, this bike was bought new in New Zealand, for all the skeptics it came with aftermarket pipes, doublebubble and a tail tidy. You can visit
Suzuki New Zealand - Street its called the "suzukifeast" promotion and all gsxr's come with aftermarket pipe for the same price as without.
Sorry if I (or anyone else) offended you.
If you would have posted ALL the info you posted in the last posts you put up, you probably would have gotten
a lot different response from most of us including me.
We (me for sure) are not mind readers. I have never heard of a dealer putting on aftermarket pipes for the same price as stock plus a difference screen and tail.
But then again you didn't let us know that it was a left over 2013. If we had known that, it would have made it more believable that a promotion
was or could have been in place as they were trying to get rid of a 2 year old new bike. Plus in you first post it appears that you also got to keep the stock pipes, right?
If so, then you really got a deal. However the "deal" also has come with a noise your not happy with. So only time will tell if you get it fixed as to how good of a deal it was.
Now for some things to check.
First I would look at the wheels. Especially if they are in balance. There is a small possibility that they are not balanced correctly - maybe just one wheel is out of balance.
How much gas have you run through it. 2 year old gas might make a difference?
Could the brake pads be dragging on the rotors any? Is the rear wheel in perfect alignment? Is the chain to the proper tension?
How many miles are on it? Have you changed the oil yet? Changed my first oil at 500 or 600 miles.
IDK if any of the above could be causing your buzzing sound - but it can't hurt to check.
