55-60 MPH vibrations common? Drives me nuts sometimes...

Mightbaal · 06-17-2016, 04:10 AM

Well I do a lot of driving to my parents and my brothers house to work on my bike as I keep all my tools there but the back roads are 55 mph so I run WOT in 5th the whole way which is about 55-60 mph (gps on my phone because my speedo crapped out). It drives me nuts but my feet vibrate a lot! Cant feel it in the handlebars tho.

Mightbaal,
Sounds like tire pressure, I settled on 12 psi front and 13 psi back. When looking online found a couple of good sites. They expland 'dirt bike tire pressure' well, sorry I don't have links.

Best,

12 / 13psi Really !!..... on the road ...... sealed roads ?

check the engine mounting bolts are tight...

also make sure your chain is in good shape, no stuck links etc. I had a nasty vibration at 45 mph on my CBR and it was from a sticking chain link

I keep tires north of 20psi on the road. Like Pete says, ensure the engine mounts are tight. All of 'em.

If you have a non-balance shaft CG motor, they buzz like crazy, especially new....but like Pete and Weld said, also check your motor mounts.

Make sure the sun flower stalks are not jammed in between the break lever and the chassis dragging the ground. It's annoying and also a surprise to not be able to use the brake...

as others have said, motor mounts, and yes... non balance shaft motors buzz like heck at 50+....my cg200 has always buzzed like crazy on my 35mi commutes, have tried everything to get it to go away.... I just accept it as fact and don't let it ruin my ride.... yiur hands and feet will stop tingling in a half hr or so.....LOL
