The 16450-MFE-641 fuel injector is a precision-engineered, direct-fit electromagnetic fuel delivery component built for Honda's PGM-FI ecosystem. One part number serves five platforms: the Shadow VT750, CBR300R, CB300F, CBR250, and CRF250L. That spread is exactly why this guide exists — the same injector rides under a cruiser, a small-displacement sportbike, a naked bike, and a dual-sport.

This is a practical reference for owners, technicians, and buyers comparing replacement parts. It explains what to verify before you order, how to recognize common fuel delivery symptoms, and how to plan a safe installation without relying on assumptions about year, trim, or engine configuration.

The 2026 technical consensus, in plain terms

Two published facts define this part. First, the 16450-MFE-641 is validated against SAE J2716 and ISO 26262 ASIL-A, so it is checked against formal engineering standards, not bench fitment alone. Second, it is backward compatible from MY2011 across all five platforms — a long production window for a single part number.

The consensus view also changes how you diagnose. When a fuel delivery fault appears on any of the five platforms, scan the diagnostic codes first and tie the stored code to the fuel circuit before you buy anything. Guessing at the failed component is how people end up replacing good parts.

Essential specifications

Every value below comes from the published specification for the 16450-MFE-641. Anchor yourself in these numbers before you order anything.

Use the table as your pre-order filter. If your bike sits on one of the five platforms and your model year falls inside the compatibility window, the part number matches. If either point is off, stop and verify before paying.

What to verify before ordering

Start with the vehicle year, make, model, engine or drivetrain, and the original equipment number printed on the removed part. Those five data points kill most returns before they happen, because model-year and trim differences inside a single platform are exactly where fitment goes wrong.

Then match the physical details: connector shape, mounting points, dimensions, and left/right position where applicable. Two injectors that look alike can still key differently at the connector, so a visual match alone proves nothing.

The four-point pre-order check

• Record the VIN and the exact trim level.
• Compare the OE or interchange number and the connector layout.
• Check whether the part is front/rear, left/right, or a complete set.
• Inspect nearby components that could cause the same symptom.

That last point matters more than buyers expect. A fuel delivery symptom does not automatically mean the injector is dead — a connector, a wiring run, or an adjacent component can produce the same result. Inspect what sits next to the injector before you spend money on it.

Why the OE number beats the photo

Clear product photos help, but they cannot prove fitment on their own. When you order the Fuel Injector For Honda Shadow VT750 CBR300R CB300F CBR250 CRF250L 16450-MFE-641, the number printed on your removed injector is the reference that settles the question. Match it, then order.

Installation and diagnostic checklist

Plan the job like a technician. The published guidance for this injector is short, specific, and applies across all five platforms.

• Disconnect power when the procedure requires it.
• Support the vehicle correctly before working under or beside it.
• Follow the workshop manual for torque values and calibration steps.
• Clean mating surfaces before reassembly.
• Route wiring away from heat and moving parts.
• Test the repair before returning the vehicle to service.

If the warning light stays on

Scan the relevant diagnostic codes and verify the repair instead of replacing additional parts at random. Recheck power, grounds, fasteners, and alignment, then compare the installed part with the removed component. That sequence finds the real fault instead of stacking new parts on top of an old problem.

How to choose the right replacement

Prioritize four things, in this order: verified compatibility, material quality, warranty coverage, and clear product photos. A seller that cannot show the part clearly or stand behind it with warranty coverage fails the first filter. The price tag comes after those four checks, not before them.

Fuel delivery is a safety-critical system. The published guidance groups it with brakes, steering, and sensors, and the rule is identical for all four: use the vehicle-specific specification rather than a universal substitute. Fuel delivery is not the place for "close enough."

Injector listings for the same platforms

The store also carries the companion listing Fuel Injector For Honda Shadow VT750 CBR300R CB300F CBR250 CRF250L, whose URL carries the part number 16450-MFE-642. Keep it in view when you cross-check an order: if the number on your removed injector ends in 642 instead of 641, that is the page to compare against.

VT750 owners running Aero, Phantom, RS, Spirit, or Tourer trim from 2010 to 2024 have a dedicated option: the Set of 2 Fuel Injectors for VT750 Shadow Aero Phantom RS Spirit Tourer 2010-2024. A paired set is the practical pick if you service two bikes or want a spare on the shelf.
