2023 — Honda CB400 Super Four Ver S / 399cc
Honda CB400 Ver S
Cinematic Cockpit Build
The CB400 Ver S served as a platform for exploring cockpit ergonomics, gauge aesthetics, and cinematic documentation. The Daytona Velona60 integration became the centerpiece — a precise, analog instrument in an age of digital clusters.

Design Philosophy
Japanese urban riding demands a cockpit that is both tactile and visually intentional. The Ver S platform offered the perfect proportions to experiment with gauge placement, bar positioning, and purposeful minimalism. The goal was a cockpit that communicates: this machine was thought about.

Problems & Fixes
Problem
Daytona Velona60 speedo calibration was reading 8% high against GPS.
Fix
Adjusted the wheel circumference setting in the Velona60 calibration mode. Now within 1% of GPS.
Problem
Clip-on vibration transmitted harshly to hands on the CB400's inline-4.

Custom Gauge Bracket

Fabrication Notes
The gauge bracket was the defining piece. Three prototypes in cardboard before committing to aluminum. The final bracket holds the Velona60 at exactly 15° toward the rider, matching natural sightline when in a relaxed riding position on the clip-ons. Edges hand-filed and finished with a matte clear coat to prevent oxidation.
Future Plans
The CB400 is complete as a cockpit study. Future direction: explore a seat cowl to complete the rear visual. The stock seat works functionally but breaks the line. Also considering a brushed stainless headlight bucket to complement the Velona60's aesthetic.
