vibration at highway speeds

[ahh-cool]

Hello all,
I just bought a used 2012rt-s with 650 miles on it. still getting used to the ride.
I have 2 concerns:
when I'm in 5 gear the bike sounds like it's struggling like it needs to go into the next gear (5000 rpm)
When I take it above 75 or so I start to get a small vibration.
any information you can give me will be appreciated.

I thought I was having a MPG problem but I guess that most of you are getting around 25 or so.
I filled it up the other day to where the gas was almost to the hole, and I got 124 when the light came on

Welcome! The engine in the 2012 likes RPMs. The sweet spot is 5000, it loves to run there. It took me a while to get used to the higher revs but now it's not a problem. The small vibration at speed is usually drive belt harmonics, if it comes and goes that is it. Of course it could also be a tire out of balance. So rev it up and enjoy the ride.

It takes a bit of an "Adjustment Period", with the high-rpms that the 998s like!
Do you have an SE-5, or SM-5 transmission? If you have the former; upshifting at approximately 5,000 rpm through the gears, will keep the revs up high enough to keep the clutches locked up fully.
The vibration at about 75 mph is normally the drive belt setting up a bit of it's own dance step. Most of us use it as a way to keep track of how fast we're going...
That's not to say that it couldn't be something else; but that's the normal mph where the belt makes it's presence known...
Now... :nopic: :2thumbs:

I'm a bit of a newbie but with putting about 1200 miles on my 2012 over the last couple of weeks, I have no vibrations and run comfortably at 75 to 80 mph.

I write my mileage on my receipts and averaging just over 30. Mostly solo rider, premium no-eth.

It's not every bike that is affected at those speeds; it has a lot to do with the belt tension.
Non-ethanol fuels will always help you get better mileage.
