For the last few
years, the Honda
250 has been easily among the fastest bikes you could buy, but it had a
flaw. The bike was all top end, with a weak hit down low and a below
average mid-range. This, combined with a demanding chassis, made for a
hard to ride bike.
While most of the
rest of their 2005 line was released, Honda simply did not release the 250
2-stroke until the got it right. This year, finally, the Honda 250 has a
user-friendly motor . How the got it is in the rather detailed updates.
The suspension and balance of the chassis is largely unchanged. All this
for $6199.
New for 2005
- New cylinder
design features RC exhaust
valve housed in removable case for improved sealing and
performance.
- New precision-cut
stainless steel cylinder base gasket and revised port timing for
improved bottom-end and mid-range power.
- New cylinder head
combustion chamber shape for improved bottom-end and mid-range power.
- New one-piece exhaust
valve for improved sealing.
- New piston dome
shape for improved intake charge flow.
- New piston
features single keystone piston ring for reduced friction and improved
sealing.
- New crankshaft
design for improved drivability.
- New crankcase
with redesigned intake port for smoother air flow and increased
journal thickness to decrease crank deflection.
- New six-petal reed
valve with narrower profile for stronger bottom-end power.
- New reed valve
mounting angle to improve charge flow and top-end power.
- New ECU mapping
and RC valve control settings to match new engine
power characteristics.
- New exhaust pipe
shape has increased volume for improved low- to mid-range power.
- Thicker radiator
core (from 24mm to 28mm) improves cooling capacity to handle extra
power.
- New front axle
placement for improved fork action and turning.
- New swingarm
features a dual-axis, double-taper design with a large cast aluminum
cross member that is lighter weight and stronger.
- New rear hub is
stronger and lighter.
- New rear shock
valving for improved bump absorption
- New Honda
Racing-inspired graphics.
Engine/Drivetrain
- Liquid-cooled
two-stroke single-cylinder engine with 66.4mm x 72mm bore and stroke
and 8.5:1 compression ratio.
- Air intake boot
is shaped for direct airflow, contributing to strong low-speed engine
performance.
- Foam gasket
between airbox and air boot for better sealing and airflow management.
- Lightweight 38mm
flat-slide Mikuni TMX carburetor provides both initial throttle
crispness and instant throttle response to complement the engine's
power character. Carburetor now has throttle position sensor (TPS) to
calibrate timing with exhaust valve for improved power delivery.
- Crankcase reed
induction with carbon fiber six -petal reed valve contributes to
excellent off-idle throttle response and top-end and over-rev power
delivery.
- RC-style exhaust
valve features an NSR road racing-inspired rotary flap design with
electronic control. The electronic control module uses engine rpm and
throttle (TPS) opening to calculate exhaust valve position and signal
a DC servo motor to adjust the RC valve, providing both a smooth
transition from low- to mid-range rpm and a broader torque curve.
- Exhaust header
and expansion chamber are designed to maximize top-end power delivery.
- A 16-bit CPU
incorporates both the DC capacitive discharge ignition and exhaust
valve servo control, producing immediate data calculation and
extremely accurate ignition and exhaust valve timing for maximum
performance.
- Dual radiators
permit forward engine placement and provide significant cooling
capacity.
- Steel water-pump
gear for excellent reliability.
- Eight clutch
plates provide significant surface area to handle the engine's torque
while carefully matched clutch springs provide a light feel at the
lever.
- Clutch damper
design improves rear suspension feel and action while accelerating
over bumps.
- Lightweight
magnesium clutch cover.
- Durable
five-speed close-ratio transmission offers consistent performance in
demanding conditions.
- Primary
kickstarting system allows starting in any gear.
Chassis/Suspension
- Revised
suspension settings deliver more controlled suspension action along
with a plusher ride.
- Third-generation
twin-spar aluminum frame delivers superior rider comfort and
maneuverability.
- Semi-double-cradle
design features a single large-diameter, tapered downtube. Two rugged
box-section rails attach to the base of the downtube and support the
engine. A forged aluminum steering head provides a compact and
extremely durable mount for the frame spars and engine downtube.
- Swingarm features
a dual-axis, double-taper design with a large cast aluminum
cross-member.
- Front and rear
wheels feature HRC(r) works-type lightweight aluminum spoke nipples to
help reduce unsprung weight.
- Front wheel
features large-diameter front axle and wide wheel-bearing span for
additional rigidity.
- Optional 20-inch
front wheel improves cornering traction and rider comfort.
- Rear axle
diameter of 25mm and large-diameter bearings provide significant
rigidity to withstand torturous track conditions.
- Lightweight, 47mm
inverted Showa(r) twin-chamber cartridge fork with aluminum rods
features 12.4 inches of travel, 16-position rebound damping
adjustability and 16-position compression damping adjustability. The
inner surface of the front fork outer-tubes receives the same honing
treatment as works bikes for low-friction operation.
- Pro-Link(r)
single-shock rear suspension features a fully adjustable Showa rear
damper and12.6 inches of wheel travel, separate low-speed (13
positions) and high-speed (3.5 turns) compression damping adjusters,
and 17-position rebound damping.
- Rear shock's
damper piston diameter is 50mm for consistent performance under
demanding riding conditions.
- Compact
twin-piston front brake caliper, anodized aluminum brake pistons and
lightweight front brake disc reduce unsprung weight for improved
turning and handling.
- HRC works-type
rear brake system integrates the rear master cylinder and fluid
reservoir, eliminating the rear master cylinder reservoir and hose.
- Large, 240mm
front and rear brake rotors provide optimum braking control.
Additional
Features
- Aluminum Renthal
971 bend handlebar.
- Frame design
allows sidecovers to have larger air intake ducts, contributing to
significant airflow in the mid- and upper-rpm ranges.
- Carefully
developed ergonomics position the rider's legs at the narrowest
cross-section of the frame for improved comfort while maintaining
excellent handling feel.
- Brake pedal and
shift lever are designed to complement the riding position.
- Brake pedal
features optimized ratio to match integrated rear-brake master
cylinder design.
- Seat cushion
follows the shape of the fuel tank, providing a smooth transition to
increase rider mobility and comfort.
- Non-slip seat
cover for increased rider control.
- Wide, cleated
stainless steel footpegs are improved for self-cleaning, corrosion
resistance, provide excellent grip and fold for extra ground
clearance.
- Cleated rear
brake pedal, shift lever and folding shift lever tip are made of
lightweight aluminum.
-
Adjustable front brake lever for maximum control.
- Quick-adjust
clutch perch.
- Dunlop D742 front
and D756 rear tires for optimum traction and cornering.
- CR handlebar
holders provide three different mounting positions: standard CR(r)250R
holder provides neutral position and optional holder
(CRF(r)450R/CR125R/CRF250R-type) provides +/-3mm fore or aft position
to match rider preference.
- Works-type
handlebar grips add to rider comfort.
- Front disc brake
cover helps protect rotor and caliper from damage.
- Removable rear
subframe allows easy maintenance.
- Washable,
two-stage foam air filter for optimal engine protection and easy
maintenance.
- Repackable
silencer for maximum performance and minimal noise.
- Comfortable,
durable controls and high-quality fasteners.
- Stainless steel
clutch cable for long life.
