Font Identifying

I identify as that font. 

It's likely based on Druk Wide Heavy Italic, from the Druk font family. https://commercialtype.com/catalog/druk Font licensing can be expensive, especially when used commercially. In this case, a less expensive variation could exist via another designer or font foundry, or a designer could have created this custom by editing an existing font. I've done a quick sketch below which yields a result pretty close to what's on Chase's bike above:

So now as well as the alphabet people we're going to have the number people? 😂 I can't keep track of it all these days...

Does look pretty cool though, not a fan of the Lawrences number fonts though that's no dig at them themselves and I appreciate the importance of standing out and branding and moreso that it is personal preference. When you're that fast you can do what you like!

Edit. Pumpkin, solid job there dude 👍

Perhaps it is "Papyrus"

Haha! Too good. I really wish someone would start playing with their ID like this. TLD & Troy do an awesome job of mixing it up for certain races. Sometimes Barcia will have that Speedway type of font on his bike...so cool. Aside from Military Appreciation Week where teams will use a stenciled-looking font to mimic techniques used on military equipment, there isn't much else that teams make unique statements with. Three cheers for TLD's commitment to style!

That’s compacta bold italic , slightly modified . 

Thought only Brick from the Middle was in to fonts.

I miss the bold stenciled and hand cut single digit numbers that the pros ran in the mid to late 80’s!
