Its not about the costs, Its about the build!
Oh, BTW, RAD manufacturing has gone out of business. Do you know of any center hub I could use to build a set of wheels? I really want laced, as you know....ha ha. Any help on this end would be awesome.
i'm always building to a budget, so cost is important with me. i rarely will buy anything for the bike unless cheap, too easy to blow the budget. for me, building on the cheap is fun. then ya get to park your slammed together ride next to some guys new 2016GSAW with the Touratech catalog on it and think... one of those, or twenty of these. his bike has already depreciated 3X or 4X the total cost of yours.
the RAD closing was sudden and caught most by surprise. i haven't heard much discussion on the reasons for closing, but with all the inexpensive hubs coming in from China, that had to be a factor. i did hear that Chinese hubs for the Versys were available, but i had no interest and never followed up.
i've run Suzuki cast wheels on the ER6 familiy of bikes, including the Versys forks with Versys clamps, so it's a good bet that the new DL650 spoke hubs would work with a little finesse dealing with the DL 17mm front axle. other hubs have been used, including the popular DR650 cush drive rear, and various fronts which can be fitted with 20mm ID bearings. running spokes on these bikes might require a little machine work depending on the hub, but nothing very difficult, and there's usually a write-up for reference.
