I've spent the last hour searching and have not come up with an answer. I'm particularly interested in seeing if the dual range transmission fits over/around the swingarm bolt. for a street legal xr200 02' Where I live, Rocky Mtn's, many good trails are 10-60 miles of paved or dirt road at relatively high speeds (40-60max)Ok for stock gearing and many of these trails are not only steep and rough, but at 8000-12000ft you bike gets a little sluggish and cant handle the steeps with the stock gearing. Thats where the low range would be perfect. Thanks in advance!
