In stock and ready to ship — made in-house by STFU.
Build to Order
Our proprietary big bore kits, pistons, rods, and cams — built to spec for your engine. No backorders, no guesswork. Tell Roxy what you're running and she'll line up the right package.
An AI-native shop
STFU Motorcycles is built around Roxy, our AI front of house. Roxy answers the phone, replies to email, walks you through M8 tech questions, and handles your order from checkout to tracking — day or night.
Every product is designed and proven by STFU founder Scott Tomsu and made in Lafayette, Louisiana. We only sell what we'd run ourselves.
"Tell me what you're riding and what you want out of it — I'll find the right kit and get it on the way."
