My 18sgs did it above 75mph. Added a true track to the rear and sent my legend suspension back in for a heavy duty spring on my revo shocks (im 250lbs). Those 2 things improved the stability by 80% or so. Hope that helps you
I think I will have to install the True Track I had one on my 2010 SG and it worked well. I didn't think I would need it on a 2018 CVO
Thanks for your help
Are you still on stock suspension? I Highly recommend atleast some aftermarket rear shocks. Legend, ohlins, fox, etc..... anything! Factory shocks really are terrible imo.
