Featuring blazing 4-stroke engine performance and a unique dual
silencer exhaust system, the hard-charging CRF250R delivers up a
potent blend of quick-revving, race-bred 4-stroke performance and
crisp, responsive handling that dominates the motocross circuit's
tight berms and big air jumps.
Like its bigger brother - the CRF450R - the 250's lightweight
and rugged aluminium frame and fully optimised suspension systems
are now complemented by an amazing new Honda Progressive Steering
Damper (HPSD).
The HPSD extends one's riding capabilities with smoothly assured
handling through the roughest track conditions, providing amazing
control that smokes the competition right out of the box.
The earliest versions of HPSD first saw action aboard the
American Honda Racing Team's CRF450R and CRF250R race bikes during
the 2004 AMA Supercross series. Ongoing development work saw HPSD
installed on additional Honda Works motocrossers including Europe's
highly successful World Motocross contenders, Team Martin
Honda.
This intensive four-year period of development and testing of
various damper settings under top-level racing conditions led to a
finalised design and integration on the 2008 models.
Team Honda riders have also discovered that use of HPSD permits
the use of distinctly stiffer front suspension settings than had
been possible without the steering damper.
All of this highlights the benefits of Honda's innovative
engineering, as do the various additional upgrades that have been
made to the '08 CRF250 including:
- New piston with 13.1:1 compression ratio
- New cylinder head porting for improved power
- Lighter weight valve train components raise rev limit to 13,500
rpm
- Lighter weight counter-balancer shaft and drive gears
- Dual-muffler exhaust system centralises mass and reduces
turning inertia
- Revised camshaft timing for added power
- Revised carburettor jetting gives smooth power delivery under
all riding conditions
- Engine torque now reaches maximum at 8,500rpm
- Clutch features judder spring for smoother engagement
- Front fork triple-clamps feature 22mm offset for improved
cornering
- Showa fork features a larger cartridge rod and new cartridge
oil piston for improved oil flow and less friction, plus stiffer
springs for improved mid-stroke action
- Rear damper valving matches changes to front fork
- Works-style front and rear brake rotors reduce unsprung
weight
- Rear fender shape for improved mud protection
- Larger left-side engine guard
Along with these new features, the CRF250R continues to offer
superior Honda technology such as a magnesium ACG cover, clutch
cover and cylinder-head cover to reduce engine weight, as well as a
lightweight, compact, internal, auto decompression system and
handlebar-mounted hot-start system providing for superb
operation.
The bike's twin-sump lubrication system separates the oil supply
for the crankshaft, piston and valve train from the clutch and
transmission.
This ensures a cool supply of oil to the clutch, eliminates
clutch and transmission material contamination of the engine oil,
and reduces the amount of circulating oil, which permits the use of
a smaller oil pump.
With Honda Racing inspired graphics, the fourth-generation
Twin-Spar Aluminium Frame sporting a forged-aluminium steering head
supports a large 25mm rear axle diameter that provides significant
rigidity to withstand torturous track conditions.
A 50mm rear shock damper piston diameter also offers consistent
performance under demanding riding conditions, whilst the compact
twin-piston front brake calliper, anodized-aluminium brake pistons
and lightweight front brake disc minimize unsprung weight for
improved turning and handling.
The CRF250R will be available from Dealers mid October (RRP to
be advised).
