Hi Lona Wolf.BikerPapa said:
The Sportster is a good handling bike, but there is room for improvemnt, But lowering is not the way to get any bike to handle.
When you lower a bike, you decrease the lean angle, the lesser the angle, the harder it will be to turn.
Also the shroter the shock are, the less travel they will have and the rougher the ride you will get.
The set-up I use one mine is a set of Progressive 418's 13 1/2' long and a progressive front spring kit.
This really smooth out the ride and improved the handling, but it Raised the saddle about an Inch.
I hope this helps.
