I think that idea has a lot of potential. The rhythm of a motorcycle engine, steady yet powerful, could be captured with strong lines and subtle shading that echo the motion of gears. Old‑school ink, with its clean, bold outlines and minimal color palette, would give it a timeless feel while the pulsating lines could mimic the engine’s heartbeat. It would be a striking design that balances heritage and motion.

That’s a solid vision. Keep the lines clean, let the heartbeat pulse through the design, and we’ll make sure it feels both classic and alive on the skin. I’m ready to help you bring it to life.
