Pro Bikes after they get back to the shop.

Here's a time lapse video of Trey Canards bike torn down and rebuilt.

They typically don't go back to the shop. They get rebuilt on the truck and the stuff that needed freshened up gets mailed back to shop for service. It is then sent back to the truck and the process repeats.

Every part has a lifespan. Some parts are only used for a single moto, like clutch plates for example. Other parts may get used the entire season like the seat pan or airbox.

The bike is completely disassembled, cleaned and inspected. Anything that is damaged or worn gets replaced or rebuilt along with the parts that are scheduled to be replaced. The frame and swingarm is inspected and remains in service until their expected lifespan is up, unless damaged. Wheels are swapped with a fresh set. The old ones will be disassembled and new spokes and rim will be laced up to the existing hub.

The engine is removed and placed in a box to be shipped to the race shop for a rebuild. A fresh engine is installed with a mixture of new and used parts. I remember a video of the Kawasaki team when RV was still racing. They had 3 engines in rotation. One in the practice bike, one in the race bike, and one spare in the truck.

The bike is built back up with new parts or used parts still within service limit. Fresh graphics are applied. New grips, chain, brake pads, cables nearly every week. Exhaust repacked or replaced, brakes simply flushed with fresh fluid or rebuilt. Nothing is left untouched.

I forgot suspension. The used set is shipped, like the engine, back to the shop for a rebuild. A freshly rebuilt set is installed. They have several sets of forks and shocks in constant rotation.

Plenty of good videos about on YouTube on the subject, pretty much containing all the things listed above by fulltime.

Are we talking about Eli Tomac's Kawi or Travis Freistat's Kawi?

Ya that's what I was thinking. Privateers wash, put in the van, hurry up To the next round! Repeat
