Yes, I know that the most cost-effective XR650L cush hub solution is the Rad Manufacturing unit. I was looking, however, for a parts bin solution that uses current-production pieces and requires no serious machining other than spacers. I think that the DR650SE rear hub fills the bill. Rather than drag this out here's what I did: Used hub bearings w/ a 17mm ID and replaced the carrier bearing with a 17 x 52 x 16 unit Sleeved the inner spacer to 17mm Obtained a DR350 rear rotor - the one w/ 10mm mounting holes that uses the stock DR650SE rotor bolts Obtained a Husqvarna CR250 (JTR 822) rear sprocket Machined outer spacers to position the rotor in the normal XR650L position The question that I've got is this - which rim width should I choose when I order the 18" rim and spokes? The XR650L has a stock width of 2.15" and the recommended tire size is 4.60 x 18. I've been running 5.10 / 130 tires, which get pulled into a rounder profile by that narrow hoop, so I've been considering a 2.5" rim. And then there's Sun's 18" rim which comes in a 2.75" width. I do mostly Forest Service and gravel county roads but I've got to travel lots of pavement to get to decent riding so I'm looking hard at the Dunlop D606. Suggestions anyone?
