Default Dual disc on a Highball?

Has anyone*converted their Highball to twin frontdiscs?
Is it as simple as just swapping out the forks/calipers/rotors from a Cross Country or aHardball to keep the wire wheels?
Or is there a different/better way?

You'd have to swap in a complete front end. the highball uses traditional forks where as the Cross bikes use inverted forks. Not very cheap. It is also worth noting the wire wheels on a highball don't have disc mounting points on both sides of the hubs. Some one on here may have a better explanation.

So to keep the wire wheels I'd need to swap the grind end of a Hardball by the sounds of it.

This is the second time someone has asked to convert a Victory single front disc to a dual disc setup. Is this something a lot of people want to do? I know I would, and I know someday I'll own a Highball, love the motorcycle.

I have a connection that makes custom parts. He can CNC a right lower fork leg to convert to dual disc, it's not that hard...scan in both legs and with the CAD program move the caliper mount to the right leg, save the file, send take to machine.. Makes me want to talk to him and work out the details. If it would be profitable for him..ie..enough folks to buy the product I can talk him into it.

Id be interested to see a pricing on it vs TIG welding a couple of lugs onto a right fork leg

welding on cast aluminum is a bad idea. Hit one air bubble while welding and front fork tube is shot.

What you would want is a vision front forks they would be the same 43 mm as a vegas or highball. I'm thinking you would have to have the fork tubes shortened. Not that big a deal.
Then you would need dual disc master cylinder and brake lines. Along with fender and calipers.
For $1500 to $2000 you could have a dual disc front end.
I guessed on prices.

What are you looking to gain with a dual disc setup?

I'm on VJ with this, I'd never weld a lug on a fork leg. I don't care how good a welder you are (and I'm pretty decent, but I've been inspecting them for 35 years) there's just too much shear stress on the weld for me to trust it with my life. One inclusion and the weld is weak. As far as the cost of a new, I can almost bet if he has both in his hand it would be expensive but affordable. Master cylinder and brake lines are the easy part. If you have to have Vic parts there's a couple of motorcycles that have a dual disc setup.

ok can the welding idea...other cheaper way is use two l/h lower legs and have the one on the right reversed..the caliper would sit ahead of the leg and the other original side behind but it'd work I think.
Brake line would need a splitter junction in it , no big deal.

vcc14 advantages well greater pad to rotor contact area (double)
greater heat dissipation under repeated heavy braking or long steep downhill runs.

Just one thing a couple of members here have suggested hauling on the brake lever harder and yes Im here to report that that does in fact stop the bike quicker than a half assed braking attempt, also now my back brakes working ok the application of both brakes does slow the bike down quite adequately...though under severe duress I reckon theyd fade quicker than twin disc setup

You will gain stopping power, but it won't stop you any quicker then a single disc. You'll gain fade resistance, which would be more noticeable if you're a heavy brake user.
