Shifter prob is fixed,grip heaters are fixed,LED lights are installed and adjusted to where I like them and added BRP arm rests.The LED's made a big difference but I think I will add driving lights also.I really enjoy riding this bike!I still think the ride is awesome and handling great!The air flow is so different from 2 wheels in a very positive way.Came home last night was 35 degrees and I was good!So after a bit of a rough start I'm a believer now!Thanks all for the hints,links and great info from your personal experience! Folks that share freely make the lives of us newbs sooo much easier!:bowdown:
