Ordered the Sidewinder Titanium II rear sprocket for the DR.. Should be the last sprocket I ever have to buy since it has a lifetime warranty. Also grabbed the matching front sprocket but in a 16t and matching 10,000lb chain. I took a photo of the new sprocket left and a comparable stock type sprocket from JT. I plan to install the sprockets/chain later in the week. Have not had a chance to weigh the Ti sprocket but it's noticeably lighter.
