For our two ryker's the first things that we installed were a F4 windshield. This is a must for highway riding speeds. We have one with clear shield and the other is tinted, both are very nice I could chose either as being good. The second thing that we replaced was the stock seat. If you drive any distance at all you'll find out how uncomfortable the stock seat really is. We went with Corbin seats, which were a little pricey but well worth it for what they have done for us. My wife has a 4 level titanium cage in her back and with the Corbin seat she can do love 5 hour plus rides with no issues. This alone showed me the quality that Corbin seats were, so I got one for myself and regretted not getting it at the same time as for her. Another good add on was the BRP floorboard which you can get off of slingmods for under $100, there are also good for comfort while riding we have found.
