I have a 2014 636 with about 1400 miles...only mods are an m4gp slip on, fender eliminator, frame sliders, zero gravity double bubble windscreen, and HID's

The bike is brand new and I love the hell out of riding it. When I reach 8k though, in any gear, the bike, especially the seat, get noticeably more "vibey", last until about 8.5k then goes away all the way to red line.

The dealer did the 600 mile service then I changed the oil and filter at 1000 miles myself..oil level is right in between both lines and the bike doesn't make any odd noises.

Just wondering if that extra vibration I notice mainly at the seat is normal

Thanks

I've never noticed such vibration in my 2013. I get a vibration in the front at low RPM sometime but I've heard other people getting this. I guess the tachometer isn't that stable and can vibrate.

I would check just to make sure that both bolts in your seat are in.
Make sure you lube your chain. A chain that starts to kink could cause this.
Check wheel balance or at least make sure there's still wheel weights on the tire.

Like I mentioned, I get a vibration in the front at low RPM and it doesn't concern me. You're bike is so new it wouldn't be normal for it to be coming from the engine but who knows.

You say it's happening at a certain RPM so I'm guessing the vibration goes away if you pull in the clutch when you get the vibration? Are you sure it's not linked to throttle position?

Reason I mention that is I had a power issue with triumph that I thought was happening at a certain RPM but after experimenting, I realized it wasn't a certain RPM, it was happening at a certain throttle position. Turned out to be a blown wiring harness. This was important to narrow down because a certain RPM would indicate an engine issue, where the link to the throttle position pointed more to an issue with the throttle body or electrical.

My 2013 has always been a bit buzzy at 8k rpms just about 10k miles on it I think its just the nature of the beast. It did get reduced when I installed the woodcraft clip-ons for some odd reason. It could be a lean spot in the tune for emissions reasons.

Thanks for the response. I havent experimented with it too much so I don't know if it's a throttle position issue or an rpm issue..I'll try that next time I ride. Tires are brand new and weights are on both...only time I ever feel it is exactly at 8k to about 8.5k so it's brief but there and noticeable...doesn't really detract from the ride just wanna know if it's normal or not.

And yeah mine does the front vibration as well at low rpm...if I hold the windscreen down though it doesn't do it so something with the tach/windscreen area is off lol....only hear it if I really pay attention though so it doesn't bother me either

Good to hear someone else expierences it as well. Just want to make sure everything is good with bike. Doesn't feel like something is wrong with the bike but the vibrations in that small rpm range do stand out

My bike has a spot where the vibration is noticeable. Only found it riding on the highway holding at somewhere in the high 7k range. It was really bad in the foot pegs, so now if I need to ride highway I just alternate speed a lot.

I get vibration around 35-40mph. It's a pulsing vibration on my '13 That pulses faster up to about 75mph. I can feel in on my tank. My Q3s have been rebalanced, chain is good no idea why I'm getting it.

Most bikes get buzzy through the pegs and handlebar but the seat? I'd check the bolt
