Hi I am new to this forum. I have a '95 Polaris XCR 600 I purchased a couple months ago. I have a few questions on choosing the proper modifications for me. The first thing I would like to do is put handlebar risers on the sled. Now, I am about 6'0" tall and don't know what height would be proper handlebar height for me. I am an aggressive rider for instance, I like jumping, climbing, and pinning that triple! The next mod I would like to do is put a new track with extensions on the sled, but I am stuck on what extension to go with, I would like to go from 121 to either a 136 or a 144 (tip up). For my riding style what would be best for me? For the most part I ride in eastern South Dakota and there really isn't any deep powder around here, but I do plan on making trips out west a few times each year. I would like the best all around length and lug depth for my style of riding. Thanks in advance for help!!!
