Good morning to all! Coming from a 2012 RT that had one of the best sounding engines (the Rotax v-twin) I may be spoiled. That engine didn't sound stressed right up to the redline, but I digress. I seem to be distracted by the engine vibration on this bike, removing the backrest for the driver transmits less, but it's still there. I have ordered handlebar weights from Sling Mods, and I can live with it, but I'm curious, does anyone offer a driver seat cushion, perhaps gel, that offsets that vibration? I have also noticed it's a bit wide at top and presses into my thighs a bit. Anyone with experience here, even if the fix is not seat related, I would love to hear!!

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

My 1330 cc triples have all smoothed out after they have run in a bit.
They aren’t the smoothest triple but they get better with miles on them.
They are a high torque long stroke motor, there’s not much point revving beyond 5,000 rpm.
The Sea to Sky seat is much better which, I think, is the comfort seat option.
I find if my hands are beginning to get a bit numb I’m gripping the bars too tight.

Engines vibrate. To me, it's just part of the experience. Ride a 441 BSA Victor, or a Mach III 2 stoke tripple, or a 650 Triumph Bonniville. Now those vibrate. The 998 V-Twin Rotax is a very smooth motor compared to a lot of machines.
Everyone is different. But to me, I don't have a problem with it at all.

Try a 180 degree crank Laverda Jota 1000cc triple.
After a few hours your vision goes blurry.

Actually the bore is larger that the stroke = oversquare. Bore And Stroke: 3.31 x 3.14 in. (84 x 80 mm) Max HP Power: 115 hp (85.8 kW) @ 7250 RPM Max torque is at 5000 rpm 96 lb-ft.

Fair enough, what I probably should have said, relative to to the 998 it is a longer stroke motor.
It's marginally over square at 1.05 to one as opposed to 1.44 to one on the 998 engine.
Most triples available today vary from moderately over square, like the Triumph 1215, to very over square like the Yamaha 900 triples.
The 1330 cc is very much on the longer stroke end of contemporary bike engines.
This gives it a generally lower level for peak torque and even peak power. It behaves more like an automobile engine than a motorcycle engine in that regard.

Out of curiosity, what are the handle bar weights for please?
vibration attenuators.

Not trying to start anything here, however, would that not be masking a potential problem.
In a lot of years messing with Spyders, I've never heard of them.
Wonder how many people use them?

If the vibration is being created by some sort of malfunction, yes. But vibration created by the proper operation of a machine, no. Handlebar weights have been around for a very long time. In general, motorcycles used to vibrate a lot more than they do these days. What with spinning counterweights, etc. Handlebar weights don't cure the problem. But they can lessen it.
