I will have to check on the tires. They are in good shape, and they handle well.
I have ridden many bikes and am comparing the Super 8 to fully adjustable suspension, which may be part of my problem.
I'm sure I could do $1600 of suspension upgrades for my $1600 scooter, but...that would be silly.
The front seems to be where I am having the most trouble, so I will start there.
I will keep looking for a economical upgrade and let you know.
Thanks for the replies.
