I think beating up on the design is pointless, the system depicted here could offer substantial weight saving in that the wheel spokes can be a lot lighter due to the fact the braking forces are applied to the rim not the hub.

The calipers can’t be attached to the hub as they would be turning with the wheel, if they were you would have no braking.

Its not entirely clear in the video but the calipers must be anchored to the spindle in some way, which would then have to transfer its loading through to the fork legs.

I think the design is unique and interesting, i’ll be looking out for this to see how it develops.

I guess that this “centered” system, besides heating problems, still transfers torsional load to the hub, where calipers seems to be attached, requiring wheels to have more mass. Am I wrong, or this would “throw away” the real advantage of ZTL system, e.g, reducing unsprung wieght?

Jenny,

We have just been producing 18″ and up because of demand in the custom industry. With harleys etc. We would consider building the rotary forging dies for the 17″ wheel faces if costomers want them. We are just now launching the wheels for production bikes at the CINCI dealer expo. Feb 2010. thanks for your question.

No 17″ wheels Aaron? It’s gonna be hard to win over the sportbike crowd without a 17″/16.5″ option

This system looks great. Our company holds the patents for U.S distribution of Internal brake wheels. We came up with this system 6 years ago. As for the buell bikes they never had true internal brakes.( calipers behind both wheel faces) The Buell calipers were externally mounted conventionally on the lower fork leg. We initially designed a setup similar to this one. However our current system is much cheaper to manufacture and allows the wheels to be tailored to any bike with ease. and cost is similar to a complete set of billet Pm’s or extreme machine etc. $5,500 to 6,500 dealer cost complete. Brakes, wheels any finish, rotors etc. we make them in 18″ to 26″ sizes unlimited width. Check out glenndynedesign.com The gunmetal and black set on the website was a prototype set. The production sets use all DOT brake lines and fittings. We are just now finished with our rotary forging dies for all Wheel faces ranging in sizes 18″ to 26″ we are now in full production designing different styles and setting up dealers.

yeah, but have you guys seen what honda is doing with their underslung exhaust?

man, those guys …..oh, wait. ummm…. never mind.

Seems sad to me that Erik Buell, probably the smartest man in the motorcycling industry today didn’t get this kind of attention when he brought this type (and better) of braking to production motorcycles several years ago.

What happens when heat causes the rotor to expand? I don’t see much room for the disc to expand, and I sure wouldn’t want to try and bleed them if the brake lines route through the hub.
Looks like it’s just an end-around to keep from violating Buell’s patents?

Neat looking computer generated vaporware variation on the Buell ZTL system. Simple questions screaming for answers:

1. How much does it weigh compared to the Buell ZTL wheel/brake/fork lower?
2. How does it perform under severe stress, meaning high heat, aggressive braking.

The Buell Forum at http://www.BadWeatherBikers.com has taken notice. See comments there at…

Nice, looks great, but I see the same basic idea on my Buell XB9R every time I ride her.

And no, Erik Buell did not do this to take care of any heat issues. Weight is the enemy, and that is why it was done.
