Here's a direct quote:
"I can do any size you want for the MaxDaddy. It is priced with our Level 1 pricing + the shaft drive upcharge. We do not press bearings in only because John Cornell never wanted us to, but if you give me a bearing size or axle size, I can get bearings for your applications. The hub we have is a cush drive set up, and we shrink fit new nylon bushings into each rear hub. For John, I usually run 17x5.5 wheels for him, but the 17x5.5 wheel blank has a different lip profile than our other sizes. So keep that in mind if you have a customer that wants a full set of wheels in one of our other patterns, we will have to build a 17x6.25 or an 18x5.5 if they want a matching front wheel from us. The 17x6.25 takes a little more work to fit into stock swingarm...I believe you have to take the brake caliper off, then fit the wheel in, and then secure the shaft and caliper back on once wheel is in position. We do wheels for another company by the name of MadMax. They usually do custom V-max builds. For example, we have done 300 and 330 wheels for a few of his turbo charged custom builds. Let me know if you have any other questions or concerns, I would be happy to address them."
