Overview[edit | edit source]
Honda CRF 250 Rally
The CRF250 Rally is almost identical to
the CRF250L, but has a larger tank (10.1L / 2.7 US gal / 2.2 Imp
gal.
It has excellent ground clearance and
long-travel suspension - this however means that the seat height
is 895 mm / 35.2 in. Al;so dissimilar to the L, the front
shocks are 43 mm Showa units and the wheels are 21 inch front
and 18 inch rear. It also has a larger front disc with
switchable ABS. A skid plate protects the machines underside
and the gear lever features a folding tip to give it a little
more chance of surviving tumbles, or tangles with the scenery
The CRF250 Rally is designed to cover
distance and its styling reflects this. Derived from the parts
used by the CRF450 Rally, the floating screen, upper/lower
fairing and side shrouds effectively shield the rider to offer
excellent defence against the elements. Handguards offer further
protection, both for the hands and the brake and clutch levers.
From the machines mid-section back, the
style is MX-sharp, with side panels and a seat/tank interface
that help the rider move freely. A skidplate protects the
machines underside and the gear lever features a folding tip.
Seat height is 895mm, 20mm taller than the CRF250L.
The headlight is a compact, asymmetric,
dual LED unit while the rear light, LED indicators and
numberplate bracket tuck discreetly away. Cohesively laid-out,
the digital dash features a speedo, tacho plus fuel gauge and
clock. The 10.1L (including 1.6L reserve) fuel tank delivers a
range of over 320km thanks to fuel consumption of 33.3km/l (WMTC
mode). The flat filler cap is hinged for convenience.
The CRF250 Rallys frame is constructed
from steel, with twin oval-section main spars and a semi-double
cradle. A wheelbase of 1455mm is matched to a 28.1° rake with
114mm trail and ground clearance of 270mm (15mm more than the
CRF250L). Wet weight is 157kg. A new 43mm Showa inverted fork
shares the same 250mm stroke as its sibling, but with 50mm extra
overall length.
Engine/Drivetrain
Compact and sophisticated liquid-cooled DOHC 249cc
single-cylinder four-stroke powerplant produces smooth and
consistent torque at low rpm, plus excellent high-rpm
performance.
A 38mm throttle body (up 2mm from the 2016 CRF250L) combines
with a revised airbox, reshaped air boot, new muffler design and
a larger-diameter exhaust head pipe to provide improved response
and better power in the low and midranges.
Programmed Fuel Injection (PGM-FI).
Extremely compact roller rocker arm design for the low-friction
valve train allows the use of a smaller cylinder head.
Gear-driven counterbalancer shaft helps reduce vibrations for
rider comfort.
Electric start for easy starting.
Lightweight aluminum crankcase.
Maintenance-free CD ignition.
Heavy-duty clutch offers smooth, progressive engagement.
Smooth-shifting, versatile six-speed transmission.
Heavy-duty O-ringsealed chain for durability and reduced
maintenance.
Quiet, USDA-qualified spark arrester/muffler.
Maintenance-free sealed battery.
Chassis/Suspension
Rally-type floating screen, fairing and radiator shrouds
provide wind protection, with the rest of the machine showing
off minimal MX style.
LED asymmetric headlights, as are the turn signals.
Large fuel tank allows extensive range. Chassis developed specifically for the CRF250L provides excellent handling and agility. Lightweight semi-double-cradle high-tensile steel frame. Strong 43mm inverted fork provides 11 inches of travel.
Pro-Link single-shock rear suspension delivers 10.3 inches of rear-wheel travel. Tapered aluminum swingarm. Powerful wave-design 256mm front disc brake, and 220mm rear disc brake provide strong and consistent stopping power. Meter assembly, taillight and license-plate holder have all been updated for 2017. Large floating front discplus ABS that can be switched off for the rear brakedelivers stopping power. Front 21-inch wheel and 18-inch rear wheel with lightweight aluminum rims. New digital dash includes a fuel gauge and tachometer. Durable front and rear steel sprockets. High-quality handlebar with comfortable grips. Transferable one-year, unlimited-mileage limited warranty; extended coverage available with a Honda Protection Plan. Meets current CARB and EPA standards. Models sold in California meet current CARB standards and may differ slightly due to emissions equipment.
