My 2010 SG front suspension feels rough at fwy speeds over 65 mph on certain roads with close together bumps. It shakes bad enough to were I feel unstable. Tires are balanced and in good condition. Dose anyone else have this and if so what have you done to improve it?

 

I also have a 2010 Street Glide and the closest thing to what you describe that I have encountered was buffeting from air coming under the outside edge of the fairing, this happened to me at around 65mph.

I solved this with HD air deflectors that mount to the bottom edge of the fairing.

I know they did not make the air deflectors for the 2010 street glide, but rather for the bat wing fairing....

Be sure to check for obvious loose parts if you have not already done so.

 

are you talking about the concrete fwys? there are a couple of pieces of I-10 in riverside county where one of my trucks bobs and weaves- my other truck with a shorter wheelbase doesn't display this quite as much.

-- you may be able to turn it out with a change of oil-- you are at full travel on the forks ( not lowered) ?
or maybe an aftermarket outfit like ricor could help you.

All stock with Electra Glide rear shocks 3inch vs 2 inch travel. seems related to road surface

 

right, but that "oscillation" can be tuned out by changing damping-- air in the back, oil in the front

try changing air pressure in the rear- it's cheaper!

Did you see the videos last year when Honda grooved the pavement on a stretch of road near victorville??

if you drove it at a certain speed, the tires would "play" the william tell overture

check youtube

Yep try the heavier fork oil and then get back with us.

but, if its the same stretch of road, it could be the weird harmonics/geometry/physics.

some areas of roadway i know are going to make me feel squirrely so i deal with it when it comes around
