I am thinking of building front hubs for my YFZ. I am a machinist and have axis to CNC machines. I was thinking of making them in a +1 or +2 per side or both. Has anyone ever herd of such a thing? If your hubs are +2 you would not need wider a-arms. Do you think this would work or a waste of time? I don’t race MX so I think they would work just fine.
Does any one know if the banshee, raptor and YFZ have the same front hub? If this works out maybe I could make a few extra sets. Thanks for the help.

 

There is already a company selling +2 hubs for the Raptor. I was doing research on which hubs to buy for my Raptor and I came across them. I can't remember the name of the company, though.

Using wider front hubs will give you the exact same effect as using wheel spacers or flipping your rims around. It will widen your front end making it more stable in turns and less tippy (not really a problem with the 450).

Here are the downfalls of having the extension being outboard of the axis of the spindle.

1) as with any extension it will require you to revalve and/or respring your shocks to get the same performance. On the 450 the stock shocks are generally a little stiff for average trail riding, so if this is what you ride it may actually soften things up a bit.

2) It will change the steering geometry. The wheels and tires will rotate about a wider radius. The steering will feel different. When you hit a bump, rut, root or rock in the trail there will be greater leverage on the spindle, it will push harder on the tie rods, and eventually push harder on your wrists. Basically, you will feel each bump pushing or pulling the handlebars more. This will lead to more arm pump and a more twitchy ride.

3) If the stock 450 uses the same cheap weak tie rod setup as the Raptor you will bend ALOT more tierods. I know from experience.

You would be able to sell some of these hubs, but I would suggest taking that money and buying a set of wider a-arms if you want to make your front end wider. Anyone please fill in what I missed or correct me if I am wrong.

Thanks RR1 for the input. i didnt think of added leverage on the tie rods.
Well i will have to build my one tie rods. [img]i/expressions/face-icon-small-smile.gif[/img]
