G310R Riding Experience - Vibration, etc.

My dealer called me up for a test ride as I have a deposit down and they recently acquired a demo. The odometer showed 1033km when I took it out and I put on about 40km, riding through traffic, a winding country road, and on the highway. In that time I ran it through the gears and took up to 96kph and just shy of 8000rpm.

The first thing that stuck out for me was how light the clutch is. It's requires so little effort compared to anything else I've ridden and even compared to a recently sold Moto Guzzi V7II which I thought at the time had an especially light clutch.

I would say that 1st gear could be a bit more useful but it's okay. I could see it being handy to crawl through a traffic jam although it seemed a bit late to engage. Initially I experienced the neutral shifting issue (easier from 2 to N, than from 1 to N) but by the end of the test ride I didn't have any problem going from 1 to N.

The size and weight of the bike are about perfect for me at 5'8". I can totally flat foot both feet at a stop and the handlebar set up was just right. It's a very upright position which is my preference. It's also extremely responsive and handles much like my Vespa GT 200 which is only about 30 lb. lighter.

I observed that you can't be afraid to wind up the rpms which gets me to the main point of this post. Vibration. It's not an issue at 5000rpm and below but I found between 6000-7000 there was a lot of high frequency vibration particularly in the left handlebar grip and in the clutch and brake levers. At the same time there was quite a bit of similar vibration emanating through the sides of the gas tank which was quite noticeable when hanging on to the tank with your legs. I ride with a very light grip, but at the end of the 30 or so minute ride my left hand was a bit numb from the vibration.

I realize that a single is prone to vibration issues but I'm wondering what the experience of people who have put some miles/kms on theirs has been as far as vibration is concerned? Has it smoothed out with milage or has anyone installed heavier bar ends? Thanks!

My short experienced echoes your own, however for me it is not a issue. For a single the engine it is very smooth, however vibes at particular revs are always going to be part of the experience.

On mine, 7000 rpm @ 110kph is pretty vibe free which is the main thing here down under.

I will be on the lookout for peg damping and bar end solutions for more comfort on the longer runs, otherwise I'm happy to keep just a light grip on the tank and levers.

Maybe the handlebar can be filled with something like silicon caulking or similar filling materials?

Not sure if it's because it's the smallest engine displacement of the mono-cylinder bikes I have had, but it's the smoothest I ever rode. My previous mounts included DR650, KLR650, KTM 690 and these were a lot more vibrating than the G310R. (They all were dual-sport bikes, higher from the ground, which might have something to do with more vibration felt on the handlebars?). But for me on the G310R it's a non-issue. My commute is 35-40mins and no numb hands. I also don't feel a difference on the left hand side, will pay attention on my next ride.

Would be interesting if you can try another G310R to compare in case this is specific to the one you've tried so far...

And yes I know some people (owners of such bikes that I've mentioned) successfully inserted metal rods inside their handlebars or fitted heavier bar-ends to help reduce the vibration when it was a problem for them.

an old school fix for vibration is to fill handlebars with sand, it helps alot

Well, I did not expect it, but after test riding a 2017 Duke 390 I have ditched the idea of buying a G310R. I confess that I really wanted to love the 310 but as mentioned before, my test ride revealed a level of vibration that did not agree with me, although everyone's experience will be different. Despite the vibration I felt that I could deal with it as I did with my previous bike, a Moto Guzzi V7II.

I happened to be in dealer test riding a Honda CB300F and a couple of Dukes arrived in crates, one was pre-sold, and we got to talking about them. I arranged to test ride one just out of due diligence but after riding it for about five minutes my thinking got flipped. After another 30 minutes, some winding road and some highway speed I had to have it.

All these singles vibrate but the Duke's frequency didn't leave my hands numb and there was virtually no vibration through the gas tank. There is a high level of tech on display (literally) which gave me a moment's pause but other bikes also depend on it, it's just less apparent. The ergonomics of the bike suit me perfectly as well.

The Duke has significantly more HP and torque than either of the Honda or the BMW and it's very smoothly applied throughout the power band. It's got loads of pull up inclines and I never once felt like I as running out of room, even with keeping it under 6500 rpms (as it's in the break in period) and around 90 kmph. The display is fantastic as well.

So, through serendipity I chanced upon a motorcycle that I love and the bonus is that it was available now. I put 80 km on it my first day. With regret (and once I can figure out how to delete my membership) I will be leaving the forum. The BMW is great bike. Enjoy and ride safe.

What matters at the end of the day is that you enjoy your new bike. Have fun on your future rides!

I was also considering the Duke, it is very comparable to the 310, it has some good specs, in the end it came down to personal preference and I went for the 310.

Enjoy your bike, hope you find a good Duke forum!

I also took a look at the duke, after the beneli, and researched the heck out of em, and passed as their reliability is a major concern, they have had numerous issues with oil / lubrication etc and that was what made me pas on the duke.

I've now 2400K's up on mine, it has smoothed up noticeably. Engine, Clutch, gear box all more smooth and slicker.

Very happy with the way this bike goes now, the handling is still the standout feature.
