Honda SH 300 motorcycle
The Honda SH 300 is Honda’s iconic mid-size high-wheel scooter: a roughly 300 cc liquid-cooled single with SH styling, underseat storage, and enough mid-range for city-to-ring-road commuting. Long Easy+Evo and later Easy windows cover a decade-plus of SH 300 ownership.
Owners research the SH 300 for commuting, light scooter touring, and Easy/Evo kit matching across 2006–2016 generations.

In our Rapid Bike catalog the Honda SH 300 appears in the following generation window(s): 2006–2014 (06→14) and 2015–2016 (15→16). Even when the marketing name stays the same, wiring looms, connectors, and kit part numbers can change between windows. Always select the year / version pill that matches your motorcycle before choosing a module.
Rapid Bike kits for the Honda SH 300
Rapid Bike add-on ECUs install beside the stock ECU. They do not replace the OEM control unit. On a motorcycle like the SH 300, 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.
Which Rapid Bike products fit this motorcycle
- Years 06→14: Rapid Bike Easy, Evo

Motorcycle technical context for owners and searchers
The Honda SH 300 is researched for engine character, real-world manners, and generation-specific fitment. Riders typically look for:
- Scooter throttle: CVT tip-in from a stop
- Cruise fueling: mixture manners on open roads
- Generation split: long Easy+Evo era then Easy-only years
- Year windows: 2006–2014 Easy+Evo; 2015–2016 Easy
For 2006–2014 Rapid Bike lists Easy+Evo; for 2015–2016 the catalog lists Easy — both refine SH 300 fueling beside the stock ECU.

Rapid Bike module details (matched to this motorcycle)

- Rapid Bike Evo — injection map management, real-time lambda control, and self-adaptive fueling. The balanced street / travel option where listed.
Signals and features that matter on this motorcycle
- O2 modulation: closed-loop mixture quality during cruise and varying loads
- Injection (Inj): multipoint fuel management relative to the stock strategy
- Self Adapt: adaptive injection via the stock O2 pathway (module dependent)
- O2 modulation: closed-loop mixture quality under changing load
Install and validation checklist
- Confirm your motorcycle year against the 06→14 / 15→16 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.
