The second circuit routes cool air into
the throttle body. Cool air produces
more horsepower.
BF250
Dual Stage Induction
EXCLUSIVE
Honda’s unique variable intake system
maximizes combustion efficiency for
increased torque and superb fuel
economy. While most four-strokes use
long manifolds to deliver air into the
cylinder head, Honda’s Dual Stage
Induction uses a plenum chamber
with twin butterfly valves to vary the
volume and velocity of air flow. It all
adds up to a simple, compact design
that enhances both low speed
drivability and high-speed performance.

4-Front Corrosion Protection
™
EXCLUSIVE
Your Honda can continue to look and
perform like new with our protection
system that includes a patented
double-sealed, multi-layered paint
process, sacrificial anodes, stainless
steel components and waterproof
connectors.
All engines. Painted Cooling
Passages BF250, BF225, BF200, BF150, BF135,
BF115, BF90, BF75, BF60, BF50, BF40.
Sealed Starter
EXCLUSIVE
The starter motor is inverted in a
sealed chamber that protects the
starter bendix drive from the elements.
The result is solid dependability.
All engines BF75 and larger.
High Output Alternator
EXCLUSIVE
Most manufacturers only advertise
their “total” alternator (amp) output.
Honda advertises “total” amp output
and “charging amps”. Charging amps
is total amps minus the amps
consumed by the ignition system.
For example, the BF225 outputs 90
total amps. 30 amps are consumed by
the ignition leaving 60 charging amps
available to power accessories.
Honda also measures amps at normal
operating temperatures.

Non-Linear Mounting System
EXCLUSIVE
Patented non-linear rubber mounts
provide smoother operation at all speeds.

/LAF and Knock Sensors
EXCLUSIVE
Our linear air fuel and knock sensors
help determine the correct fuel flow
and ignition curve, enhancing overall
engine operation and efficiency.

3-Way Cooling System
EXCLUSIVE
Three separate cooling systems keep the
cylinder heads running cooler for long-
term durability.

Center Mount Tiller Handle
EXCLUSIVE
Available on our smaller HP engines,
Honda’s ergonomically designed
handles minimize driver fatigue and
improve handling. Adjustments for
