Hard vibration in the steering at 45 mph

[Peter Aawen]

My thoughts?? Defective tires, really good chance! Defective or damaged suspension, less of a good chance but still a significant chance! Under inflated tires - Errrm, not likely!!!

Certainly not likely on the front end of a Spyder where the load imposed on any one tire is hardly going to get into 3 figures of pounds..... well maybe a few hundred #'s, but not much more!! Even a crappy push bike tire can handle a few hundred #'s of load without needing massively high pressures & not causing vibrations or tread wear; and besides, there is AMPLE EVIDENCE that Kenda tires are prone to significant construction defects that lead to this sort of problem, I doubt that any court in your land or mine would consider much beyond the blindingly obvious 'smoking gun in the trunk of the bloody great elephant in the room' of it being a Kenda tire in order to decide that a defective tire was the most likely cause of your issues!! :shocked:

Any chance we can see a pic of this 'cupping or tread wear' they claim is caused by running low pressures (wot?! Lower than the pressures BRP recomends up front?!?) & that it's that giving you/causing the vibration issues you are experiencing??!? I'd really like to see that wear?!?

Hi. from Canada.

We do also have a "wobble problem" with our 2012 RTS and when it does happen we have to reduce the speed this way the wheel stop to shake. Bought it "used" 2 months ago and did get 6 big wobbles since we did buy it. The dealer verify balancing/alignement and found out alignement was not right and create bad wear and tear on the tire so alignement is ok now but damage was done to the tire so even with good alignement our Spyder still wobble between 60 kl and 80 kl . Next step I guest would be to change tire.

Hello again,

I have a 2014 ST-S. So, last night something strange happened. My wife and I were on a ride and suddenly, when I got to about 45 mph and maintaining speed, the steering started shaking violently. I looked down and the wheels were shaking so hard they were a blur. It only did it between 45 and 48mph, and would go away if I accelerated or decelerated while it was happening. We were a good distance from home, so we turned around and made our way back. I dropped her at the house and then went out by myself. The vibration is still there, but much more muted with half the weight on the bike. I did a full check over everything on the bike and did notice that my oil was low, so I topped it off which seemed to help, but I wonder if there is something else wrong due to the fact that it seems to matter if there is more weight on the bike. Could the sway bar be loose or something? My wife just left her job, so my funds are extremely limited right now. I am afraid to take it in to the shop to find out it will be a large repair bill, so I am hoping it can be something I can fix myself.

The tires are only a couple months old, with less than 1000 miles on them. We have rode together on the bike many times before and have not had this issue. Any advice would be greatly appreciated.

Thanks,

Vibrations or Wobble

are generally caused by an un-balanced wheel / tire .... so that is where I would look first .... If you still have Kenda's then read what Peter has to say ( and I agree with His assessment of the crapenda ).....Mike :thumbup:

Wound up replacing the tires. Everything is smooth as glass now. Went with Federal as opposed to the Kemda. I am still perturbed that the shop wouldn't make it right, but at least I am back on the road again.

It's because they couldn't if you replace bad tires with more bad tires.

Not surprised. Someone dropped the ball on you and then didn't have the integrity to make it right. There are still a lot of good people out there. But unfortunately, service people are like doctors. You don't know if they are any good until it's too late!

Live for the future. Ride and let the past blow by like the wind. Glad you got it fixed.

Another strike against Kenda. Knowing that they, and their exclusive dealers will not stand behind their product. BRP must be making/saving a very large fortune in order to endure the bad will created by imposing an inferior product on it's customers.....
