Initially I just built my custom brackets to fit the 06 round speedo but then later when I got the 07+ speedo it was a direct fit. To convert to the new style, you just need 1. Fairing with windscreen 2. Fairing stay 3. Inner cowls 4. 07 Speedo + 07 harness which will make it plug n play without splicing.
