It Only Takes 4 Strokes - Unisex classic tee

Four strokes. That's all it takes.

Herr Nikolaus Otto worked this out in 1876, and frankly, nobody's improved on it since. Induction, compression, the good bit, exhaust — repeated several thousand times a minute until everyone within earshot is grinning.

Because some of us genuinely do get excited about this stuff. The way it all builds. The moment it goes bang at exactly the right time. If you've ever stood next to something naturally aspirated at full chat, you know precisely the kind of excitement we're talking about.

Everyone else can read into it whatever they like. We're talking about thermodynamics. Obviously.

Vibrant enough to be seen from the far side of the paddock, this one's for the engine nerds, the pit lane comedians, and anyone whose idea of a perfect evening involves valve timing.

This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
