Unless Kyle copied my 320mm adapters too he won't have the hayabusa converison for his 2006. The adapters shown on your 85 won't work on his newer forks. Here's info I send out with what we offer (I can give you pricing if desired - email me at
[email protected]).
Options:
The adapters are $60 normally but that is for the adapters used on the 85-92 forks. For your 07 you have some other options:
1.) Bolt on (no adapter required) Sumitomo 6 Piston calipers + New Pads
This setup works quite well and requires nothing more to be quite effective. The calipers are sourced from mid 90's 750 and 1000R racebikes and usually in decent condition. The line location is in the same place as the stock setup so your current lines work well. Of course if you have not upgraded to braided lines these work well for any of the upgrades. I have a variety of line options available from $90-$150 depending on color and line types.
2.) Single Adapter, Single Rotor (320mm - New aftermarket), 6 Piston Caliper, Pad Set, Longer Brake Line.
This setup works so well we normally only suggest a single sided setup. This reduces reciprocating mass for even more more responsive handling. I have not tried a dual version of this setup since the single sided version worked so well. This modification does require some grinding of the inside of the caliper body to make sure it clears the rotor. Most don't have problems getting this done.
3.) R1 Calipers (price varies depending on which version we get you). They are a direct bolt on with no adapters needed though I do suggest new brake lines that are -2" shorter then your current line due to the orientation and location of the connections.
In my opinion ALL of the above options do not need a different master cylinder. The more displacement the master needs (for instance the option 1) the better "feel" you have and the less effort. BUT, they require more lever travel to reach the operating pressure. The R1's are closest to stock and provide the least improvement in stopping power. They are of course the least expensive route to go.
