Awesome work Bryan!
I've had some lovers and haters of my work too!
I had similar thoughts with the Triumph swingarm to fit my Tube frame Buell.
This used to be a S3T!
Respect

Jodie,
The bike looks good. You should use a Vrod headlight on your bike. |

Bryan I've already planned to use and XB Lightning setup.
I posted some pictures of your bike on aussie buell riders website, should get some good reactions!

Bryan your brake caliper mounts are works of art! |

The swingarm on my bike is not any heavier then the stock one.

that's a great looking bike! What are your ideas as far as mounting the rear brake? I didn't notice one on there. |

it is on the front drive sprocket... |

Here is a link to a photo of the rear brake.
It is attached to the front sprocket. |

that rear brake is quite interesting. First time I've ever seen one up close or even seen one for that matter. Is that to tidy up the rear tire? How would that affect brake function since it's not hooked directly to the wheel? Very interesting I'll say again |

That brake setup gets used a lot in the custom Harley world. It doesn't seem to effect function much, if any. I would venture to guess the only effect is a bit more strain on the chain as it applies some tension in the other direction. Basically you are relying on slowing the chain, and then the chain will slow the wheel. |

Since the rear brake acts on the front sprocket, the ratio of braking would be the same as the drive ratio.
In other words having greater leverage than if acting on the wheel alone.
If not engineered for this it could cause rear wheel lock-up too easily. |

I think the brake would wear out faster this way as Old_man stated above - the ration of braking would be the same as the drive ratio. I think it's more cosmetic than functional especially on a sport bike |

The inboard mounted brake, as anonymous has pointed out above, had been used in the 70's on racing bikes.
It transmitted braking forces to the rear wheel via the chain.
The advantage of it is that it reduces unsprung weight at the rear wheel, and as the disc is rotating faster, it can be made smaller for the same braking effect.
And as you suggest, it makes the rear wheel hub look cleaner too.
I believe that the technique was outlawed in racing because it was felt that if the chain broke the bike would not have a rear brake. |

If it did break then what would be your theory for slowing the bike in an emergency then? If the chain breaks you're SOL. Technology advances for a reason. It's because there is always a better way to do the same thing with less.

I'd say if the chain breaks you're SOL regardless of how your rear brake is set up. My guess would be to use the front brake... just thinking outside the box a little.  If your concerned about multiple catastrophic events occuring at the same time ie broken chain while leaned over at speed etc... we deal with that possibility every time we ride.
As far as locking up the rear wheel, would the caliper on the front sprocket/brake not be adjusted so that it didn't provide too much 'grip' Doesn't seem like matching the hydraulic ratios of the master cylinder and calipers would be any different on that setup then on any disc brake system. You just make it so that the calipers do not provide as much normal force to the disc surface by changing the ratios. Might take a little playing around with but it's far from impossible. Longer lever arm just requires less force. |

I used to tell my ex-wife the same thing in the bedroom. She wasn't convinced. |

+1 Do people use the back brake for something other than tightening up your line? The compression braking seems to provide more than enough for slowing down when used with the biggest front rotor on a production motorcycle. |
