Re-Drilling Hub Flange?
 
Is it possible to have a spoked wheel hub welded (i.e., closing up all the original holes) and re-drilled for a different number of spokes? If so, any idea what something like that would cost? I have a line on a spoked hub for my project bike but it's a 52-hole hub :huh There's not much selection in rims for that many holes, and those that are available are ultra-heavy chromed-out Harley chopper rims. Not really what I'm looking for.

What kind of project bike?

I'd be nervous drilling and welding on a hub. I think you would be better served spending some cash and getting one custom made.

Something like this?

Or there are some decent candidates in 36 hole variety just depends on what you are using it for. Front rear?

The problem is it's for a shaft-drive CX650, so I'm kinda stuck with the hub since it needs the drive flange. I suppose I could have one custom made, but I imagine the machining for something like that would be more than the cost of every motorcycle I've ever owned. :huh

I have found a couple places that make custom rims, the cost on the rim is more reasonable, so maybe I'll go in that direction instead. I don't want an unsafe wheel.

There is a guy who built a cx500 adventure bike. He was in East Texas. He did what you trying to accomplish.

Thats a tough one, I bet it would be pretty pricey to do and I think it would make me a tad nervous every time it got rode further than a few miles from home.

What are you trying to do, change the rim size? Woodys Wheels may be of some help here. http://www.woodyswheelworks.com/

Yeah, the CX650 uses a unique final drive, it's not the same as the 500s, unfortunately. If it were, I'd just use the Comstars as I really like those wheels. I'm trying to get a different size rear wheel since the 650 comes with a 15" rear for some dumb reason. I want at least a 16" rear, preferably a 17" or 18". The spoked rear might be the only way to do that, there is a spoked rear that fits the 650's odd drive flange available on one year of the Honda VT800, but it's a 52-spoke wheel, which means that most of the common rims are out.

I think the best bet if I do end up going with the spoked rear is to have a custom rim made from Buchanan's and lace it to the VT800 hub. I wasn't sure if redrilling the hub flanges was a common thing or not, since I don't have any experience with spoked wheels on motorcycles. Bicycles, sure, but there's a big difference between the two.

If you use a CX650 Turbo rear wheel it will fit the Custom final drive, but you will need to fab up a rear brake system.

Probably a little more extreme than you were thinking, but what about a chain drive conversion?

http://thekneeslider.com/archives/20...wendell-jones/

Don't know if it would be possible/feasible to have some sort of chain drive conversion done with the engine mounted transversely (stock arrangement). This one uses a jackshaft with some sort of 90 degree gear set:

Possible? Sure, anything is possible. Advisable? Hell no. As already posted, the metallurgy of the hub is unknown and if it's cast (very likely) welding to it will be sketchy. *I* wouldn't ride it. :lol3

A custom billet hub is really the only answer if you can't work with the existing number of spokes. The shaft drive interface should not be a huge deal. They would have to bore holes into the hub to mate up to your stock cush drive. Make some rubber or soft polyurethane bushings and Bob's your uncle.

Of course somebody has to design it and--realistically--the hub alone will probably cost around a grand to have made.

I'm pretty sure a good wheel shop would be able to drill a 52 hole rim for you. You can order some rims blank, without the dimples for the spokes.

Buchanans can easily drill that rim for you, those guys are pros. It's probably the cheapest solution out there.

Final Driven Flange
 
The Final Driven Flange bolted to the wheel on all the CX500/CX650 except the turbo.
The Final Driven Flange rivets, and has been bolted, to BMW wheels.
With some careful comparison and measuring you might be able to bolt that Final Driven Flange to an existing shaft drive hub that has the number of spokes you're looking for.

Thanks for this info. I have been considering trying to get a CX500 wheel and seeing if I can swap the drive flange from the 650 wheel over it. That would be my cheapest solution, so I think I'm going to give it a shot. Otherwise, I think I'll have Buchanan's make me a 52-spoke hub and have it laced up with the correct offset. Then, at least I could have a matching front wheel and choose a rear rim size to maximize my tire choices.

RedRaptor22 10-30-2012 08:02 PM

Crazy Idea here and may not be possible, but what about just leaving some empty holes on the hub and use a lower hole count wheel?

I would have to have one here to look at so I really can't do the figuring in my head, but it may be possible to just skip a hole every few spokes?
