Rapid Bike kits for the Honda GB 350
Rapid Bike add-on ECUs install beside the stock ECU. They do not replace the OEM control unit. On a motorcycle like the GB 350, that approach is ideal when you want better fueling control, more consistent throttle feel, or additional map options without a full standalone ECU project.
Rapid Bike modules help refine how the motorcycle delivers its power: mixture quality in closed loop, injection map behavior, and on higher kits ignition-related control. That matters when altitude, temperature, load, or aftermarket exhaust / intake setups change demand.

Install and validation checklist
- Confirm your motorcycle year against the 23→26 pill on this page.
- Open the chosen Rapid Bike product and verify Item Kit + Wiring codes for that year window.
- Install using the kit manual; keep connectors clean and route the loom away from heat and moving parts.
- Validate on a controlled ride: idle, low-gear tip-in, mid-range roll-on, and steady cruise in your typical use.
- If you change exhaust, intake, or regularly ride at very different altitudes, reassess maps / adaptive behavior instead of assuming the first setup stays ideal forever.
