-Dogbones(thanks thatkid!) : These raise(or lower) the rear of the bike.  Raising the rear improves the speed and ease of turn in and braking as more weight is pushed towards the front end.  I've always made mine out of 6061 T6 because it's inexpensive and strong enough.  If you can get it, go with 7075 T6.  It's about 3 times as much but has almost double the strength rating.  2024 has about a 7k lb higher rating than 6061 but isn't as easy to come by and doesn't weld very well.  Not that there will be welding of dogbones but....who knows.  Make them .25" thick and then standard dimensions after that. To lower the rear end you would want longer dogbones.

-  *The below figures should give people an idea of the strength ratings of aircraft grade aluminum.  Keep in mind any of these aluminums need to be a T6 for strength.  A 6061 0 will not be anywhere near as strong as a 6061 T6.  All data can be found at http://www.matweb.com

-    *2024 T6 - Shear Strength  - 41,000psi - Fatigue Strength - 18,000psi Machinability  - 70% Yield Tensile Strength - 50,000psi
-    *6061 T6 - Shear Strength  - 30,000psi - Fatigue Strength - 14,000psi Machinability  - 50% Yield Tensile Strength - 40,000psi
-    *7075 T6 - Shear Strength  - 48,000psi - Fatigue Strength - 23,000psi Machinability  - 70% Yield Tensile Strength - 73,000psi
-  *FZR400/600 - To raise the tail about 1.5"-2" I go with a 5"(127mm) center on center.  Stock length is 5.8" center on center.  1mm shorter bones will yield about 2.4mm raise on average.
