Hi all, i wanted to see if anyone else with a Benelli 502C is experiencing high vibration from 6000rpm onwards.
I can feel them especially on the saddle and the foot pegs. So much that just after 30 min of riding when i get off the bike i get pins and needls.

Please share your thoughts, thank you :)

Hi just bought a 2019 502c on a 22 plate had it since June now done 500mls the post above is exactly my problem when you start the bike cold there is no vibration ,after a couple of miles it starts mainly right hand footpeg and seat but also handlebars vibrate to such a degree it I get pins and needles as well question was your problem ever fixed or did you sell the bike, ps dealer not very helpful yet they ride the bike and said they could not feel it [vibrations] want them to fix if possible I like the bike such a shame

hi. Same story here! I reported the problem to the dealer and they said they could not feel any major vibrations. The mechanic told me (in all honesty), that those are “made in china” and that’s what you get. It’s a real shame coz the bike is beautiful

(Hi Everyone, new member but old boy): Parallel twins do vibrate more than other layouts, by the nature of the design: The engine here I think is a 360 crank which is meant to be smoother than a 180 design but it doesn't cure everything. Hence all the tedious internal mucking about with balancer wheels, 270 cranks etc. If you're hitting 6000+RPM on an engine with 500 miles on it (Benelli says it's 1000km or 600+ miles to run it in) chances are it's still bedding in and it would ease out over time. My own 502C, which I love, had 3000 miles on it when i got it, and still felt tight, now I've 4,500 miles it's noticibly smoother: I tend to burble around high gear low revs in town but done some 300 mile high speed runs and it's been fine. Usual suspects for serious vibration are the engine mounts: Sounds too new to suffer perished rubber but they may have come loose, low engine oil, unbalanced wheels when tyres were fitted etc etc. A partially blocked injector or inconstant fuel quality (knocking) would throw the engine off balance as well through misfring, but there'd be other very noticable symptoms it that was the cause.

Hi BermondseyBiker, I was interested in your opinion regarding the 502c. I fell for the looks and stance of the bike and am due to sit my A licence in a few weeks, my main concern is , is there enough pull through the gears to make this a long term purchase. I don't want to buy one just to discover that I should have went for a 650. I am a returning rider ( mid 50's ) so truth be told mad speed is not my aim. Given all the youtube reviews I have viewed ( which is many ) I have my choices narrowed down to the 502c or the FCMOTO 650GT .

Hi Turnaface,
Well I am a bulky chap so I favour torque over revs, and the Benelli has a decent pull, low geared 360 crank parallel twin: Torque is what it's built for. (I've not had a 4cyl since the 90's). Also my knee doesn't favour very high seats or aggressive pegs so the cruiser stance suits me well, although the backrest sometimes gets in the way of cocking a leg. My previous bike was a R1150RS beemer, a much more expensive and theoretically a technicially superior mile-eating vehicle, but it was dull dull dull.

The 502C is an "Urban Cruiser" so quite low-geared, but it cruises Motorway Legal +30MPH with me on it, if you knew me you'd be impressed. Pottering around town with the torque / 6 speed gearbox I usually stay below 3000rpm so it's extremely frugal.

Nice wide bars, good low speed handling, relaxed riding position and swoopy handling, good build quality for the price, excellent road presence as it's not a small bike, and the only real competition for a cruiser is the Kawasaki Vulcan S 650cc. That's lower and a bit more HP, but is ugly, about £2k more than the Benelli, and much more common. I was in line to get that model, except I stumbled across the 502C more or less by accident. The marketing is almost non existent, even though every review I've read is excellent, go figure.

I have had more compliments on the Benelli that I got when i was riding my FLHRCI RoadKing back in the day, and with a few tweaks (Bar-end mirrors, Puig flycreen and Easylock panniers) it easily coped with a week long summer trip to Cornwall and back, and to my club's annual Bike Rally. It never missed a beat, didn't even lose tyre pressure or need oil top up. Great fun on the A roads.

I like the firm suspension for obvious reasons given my bulk, it gives excellent road feedback, some complain too much firmness in the suspension and about lightweight braking but mine seems about right (After 30+years of riding, if I need to brake to slow down, I've done it wrong...)

Last thing to consider is that if you haven't had to buy insurance there's difference in insurance between a 499cc and a 649cc. I suppose that might be offset if you choose the more common brand.

Whichever bike you choose, I heartily recommend getting back on the road, I have no regrets at all (Not sure I'd would be able to say that if I'd bought the Vulcan :)....)

Thanks for you're input BermondseyBiker, it is nice to hear some feed back on this. I was swaying a little but the scales are tipped in the 502's favour. Many thanks, Eddie.

Just sold my 502c and bought the 650 Vulcan as I stated above I was very very disapointed in my Beneli and cant tell you how pleased I was to see the back of it , the Vulcan is better in every respect and persanally I would never advice anyone to buy the 502c even tho its cheaper and I,v owned both bikes dont do it get the kawasaki my advice dont buy untill you ride both bikes then you can make an informed decision

There is no doubt some not so good products coming out of China, but there is some very good stuff too,
Years ago my father rang me for advice on changing his car, I said get a a Toyota as there was a dealer near him, he said jap stuff is rubbish, he told me about jap screwdrivers that were sol in the fifties, you could bend them quite easily, the japs were getting their manufacturing back up and running and knocking stuff out cheaply,much the same as China started out so I wouldn't generalise and paint them all with the same brush !

I should add theres a lot to like about the Benelli very comfortable riding postion seat gave me no issues build quality was very impressive the spec on the bike high end LED lighting road handling very good tyers good its just for me personally I could not get past the vibration I was feeling . the bike was tested by the shop I bought it from and they assured me it was normal for this bike and nothing they would not expect also saying they are built to a budget in china thats when I know the bike would have to go , someone else could and proberbbly will get that bike and be very happy and I hope they are just not for me .

Well Horses for Courses of course. Perhaps my bulk dampens the vibration! After the BMW R1150RS I fancied something with a bit of character in the cruiser style, and these days that's a pretty small range in the middleweight capacities. I tried the Vulcan S but it was too "meh" for me, but as you say a pretty good and popular bike. (If you like beige :)) Bike riding is very personal and certainly I agree, road test as many as you can.

Hi guys I have a 2022 502c and it has just been diagnosed with a problem with too much play in the front suspension has anyone else had a similar problem? Unfortunately I am located in nz where there are no parts available and non in Australia so the bike is off the road....it's a pretty expensive garden ornament. It's such a shame because I love the bike

I love my Leoncino Trail. No problems at all in 13,000 miles. However from the factory the front wheel was severely out of balance, causing a noticeable vibration. Some wheel weights fixed that completely when I swapped the stock tires for some knobbies.

Charles.
