Thought I'd give you a general response to your lowering question since I have a Roadstar and not a Roadliner. I have one of my Roadstars lowered and really like it. I consider it my around town bike since the other one is set up for touring. I really like the way it handles, but it scrapes the pipes easily....especially when cornering. It also bottoms out easily even with an upgraded spring. I'm use to the issues and ride accordingly. Changing it out isn't too bad. The method I used which is available on a Roadliner is the same. You drop the shock assembly and change out the dog bones. A lot of guys lower their bike based on their height when they have trouble being flat footed while seated. I did mine for looks and handling when I changed to raked trees and a 21" front rim since it changes the trail. Good luck!

Hey, thanks for the reply! I took a peek at your garage... verrrryyy nice! Do you remember how much you had to take off to get to the bones? Seems so easy but I don't have time to start a project that''ll involve removing half the rear end.
Thanks! Removing the shock assembly on a Roadstar requires removing two accessible bolts, so it's pretty simple I did a Google search on a Roadliner for removing the shock assembly, and it's just a bit more involved. To remove the shock assembly bolts you need to remove/loosen a few things to gain access. Once you've removed the shock assembly, you just change out the dog bones while omitting the stock bushings. If you go to the dog bones link on my first response and go to the bottom of the page, there is an installation PDF.
Look at Scraper's second response in the below post. He explains what is involved for a Roadliner. They are discussing installing a Progressive Spring, but it's basically the same process. Most install the stiffer spring at this time. Also recommend the shorter kickstand which makes it more stable once lowered. Good luck!
