ztl 2 is just the calliper, rotor, and master cylinder right? I could go that way, but i just want the conversion done for now, i have the xb front end sitting in my garage. |

Ahh... the ZTL 2 has an 8-piston caliper... the first gen ZTL has a 6-piston caliper.
It's not just that... I suspect the reason the ZTL 2 caliper is so large has more to do with just the two extra pistons. It looks like Buell engineers intentionally left plently of material in the caliper body when designing the casting molds. The old 6-piston caliper looks almost dainty compared to the block like 8-piston caliper. It seems that the weight savings of the ZTL wheel gave engineers room to add material (and mass) where it could give them an advantage.
And what advantage would that be?
I'm thinking the larger caliper is also a heat sink. Increasing the material for heat to flow into from the brake pads and increasing emmisivity of the caliper body with it's black finish, as well as increasing internal hydraulic fluid capacity, all conspire to more efficiently handle heat.
This is all pure conjecture, of course, I don't have a clue what drove Buell engineers to make the changes they did, but the points I touched upon are valid in any brake system. |

danny, are you going to make some sort of bracket for the stock m2 forks or just go inverted? |

Here's another question: I know that the caliper is nicely stamped with the word 'Buell' on it, but I can't help but think that some other supplier actually private labeled it for the company. Whose caliper is it exactly? I can see that the rotor is actually made by Nissin....same with the caliper?

The coolest one (and I think I put a picture in the book) was the gold engraved 100,000th Buell caliper. |

Don't forget about the old ones. The early PM calipers. Some of them were cast, some were black anodized machined aluminum. I would like to have one of the black ones for my blacked out M2. |

"are you going to make some sort of bracket for the stock m2 forks or just go inverted?"
If I could get an entire suspension/brake assembly, I'd rather do that than make a ZTL wheel and brake work with a conventional fork. I haven't actually seen a ZTL wheel on an M2 fork, but it's entirely possible. |

Look for REX's bike, he has 2 i think

I don't believe it's a dual ZTL set-up, looks like an aftermarket perimeter rotor kit(with different calipers) installed on a stock tuber wheel. |

Here's a pic from back in the day when the Tubers were running in the Pro Thunder class. It's a left side Nissan with a bracket that adapt's it to the fork leg. I have this set-up on my track day bike and it can haul down my bike plus a couple more if it had to.

Grancuda,
I sourced the brackets from American Sportbike a few years ago.
Don't know if they can still get them or not, but i think a paid a under $200 for the pair. |
