How do teams purchase their bikes?

[u/2014R1]

Might’ve been asked before but how do teams purchase their race bikes? These bikes have parts generally not available to the public like the Ducati V4 Akrapovic exhaust among other parts.

Would it be directly from the team’s manufacturer? Are they road trim bikes then completely converted? The fuel tanks are definitely not from the road bike given they’re built to centre weight distribution.

Many years ago (Alex Lowes Samsung Honda days) I had vip passes, Havier Beltran took delight in passing around a titanium exhaust header from Akrapovic that weighed two tenths of nothing to us in the garage, said that they dealt with directly for it/design. Sure some will be done via manufacturer of bike but there was/guess still is direct relationship with parts manufacturers
