I'm getting some bouncing feel, but not a consistent vibration. Just put on new E3's front and rear with Ride-On in both. Most noticeable at 35mph. It does come and go at first I though it was the Ride-On needed to do it's thing because it seems to happen most often when just starting out from a stop. I was getting a similar feel before changing tires and thought it was caused by the severely cupped rear tire. I checked for out of round. Front tire out of round ~1/8", rear out ~1/4". Is that enough to make a difference or do I have something else going on? Thanks in advance.

read the tech info rideon has. they indicate this at lower speeds. also realize it is the road surface sometimes. I use quadboss not rideon, and it does the same thing although after 9k miles it doesn't really do it anymore except slightly in the winter. and I used the % more to acquire the balancing features, which is also in ride-ons tech.

If you checked for out of round with the tires cold, no it's not unusual. Sitting with the weight of the bike can cause a slight out of round. If you checked after a short ride, then the tires are truly out of round, and yes, you will notice.  |

.050" is the general out of round tolerance for tires. 1/8" to 1/4" is .125" to .250". Your tires are way out of spec. Balancing will never correct an out of round condition. Check the out of round condition of your wheels. If they are good, get new tires.

I had a out of round new tire on a old Honda. They ordered a new tire, but the out of round one got better after a week or two. I added a bit of soapy lube to the bead. Overinflated it. It wasn't seated on the rim.

Michvalk, thanks for the advice. I did check the tires when cold. I'll try again after my next ride.

after 30 min ride, much better. out of round is maybe 1/16". But still have an occasional bouncing. Is it time to rebuild front suspension or new shocks for rear? Or, is this just the way Ride-On feels.

Let's do some basic trouble shooting and decide if the problem is from the tires or the suspension.
1. Does the bounce occur on a smooth road where the suspension is not doing much work? If so, your problem is not in the suspension.
2. Does the bounce occur as a rebound after hitting a bump? If so, your problem most likely is the suspension. Check easy things first, like the rear shock bushings. It is highly unlikely that you need to rebuild the suspension unless you have 300K on the bike or it has been wrecked.
3. If you feel the bounce in the handle bars, most likely the problem is in the front. If you feel the bounce in the seat of your pants, the problem is most likely in the rear.
I still say 1/16" (.0625") is too much. You need to find the root of your problem.

Well you know that the molds that they form the tires in are true as can be, so any out of round condition or similar problem is with the layup of the tire threads, belts and beads.
You don't even have to be able to see a problem with a tire (such as out of round) for it to ride terrible.
The only available thing you have to work with is air pressure.
As long as the tire is properly seated on the wheel, and that was a good tip about seating the bead, there is nothing short of changing out the tire to improve the ride.
I wouldn't automatically discount the possibility that the tire is not fully and completely and properly mounted.

Yes, the bouncing seems to come mostly from the front. My gut says it's the ride-on. Although others swear by it. To me, it seems to like it's not quit in balance until you go a little faster then slow down. For it to be smooth at 35mph one needs to ride at 45mph for a bit then drop back to 35mph. Go from 25 to 35 and it can bounce some. Go from 45 to 35 and it's most often smooth at 35. I haven't tested too much, just seat of the pants right now. I'm posting to make sure I'm not over looking something else and making wrong conclusions.
As for the seating of the bead. The rib that is right at the rim seems very consistent distance from the rim.

You can swear the front end bounce is coming from the front tire and its actually a bad rear tire. Been there.
