Hello Noel & welcome to Typophile. Vitesse is a retail font distributed by Hoefler & Frere-Jones type foundry. It's not a free font and you have to buy it through their website. Though, on their website you cannot order just the bold weight, however I believe that they are reasonable people and if you really need the font you could contact them with your enquires. Good luck!

Yup, this isn't exactly Dafont. :-)
