Mike, you can upgrade the brakes and suspension. Dual disks in the front along with new brake pads, SS lines and and improved master cylinder, all available from Mikes XS. Suspension upgrades also available from MikesXS. Since Yamaha chose to rigid mount the motor in the frame to quell the vibrations you get from an unbalanced 360° twin they rubber mounted just about everything that attaches to the frame. All these years later most of those rubber mounting grommets have deteriorated or hardened. Replacing as many as you can helps with the vibrations which can be quite severe at higher RPM's. I had a small Slip Streamer Spitfire windscreen that I mounted on my XS650 that worked quite well. Its possible with a little time and money that you can turn it into a daily rider.
