As
you look at the lineup of dirt bikes from Honda, you'll note the
absence of the venerable XR 600. Yep, the time-honored air-cooled big
single, which seemingly has been around since the earth cooled, has
finally been eliminated from the Honda stable.
It's safe to say that the
XR 650 has done its intended job of replacing Old Faithful, and is
actually starting to win a whole bunch of important off-road races.
And in the Baja events, it's utterly dominating!
The balance of the line has
not received major changes, and some of the smaller XR models are
virtually unchanged except for graphics. Still, Honda has an
impressive range of models, ranging from beginner play bikes, to
supercross steeds. Let's take a look:

The 2001 CR125R returns with
chassis refinements and aggressive mid-range and top-end power
delivery.
Features & Benefits
New for 2001
- New cylinder
porting shapes and specifications contribute to improved
engine performance.
- New, larger air
intake connecting tube.
- New
4-petal reed valve combined with a new asymmetrical reed block
improves off-idle response, driveability and top-end power.
- New reed-valve stopper
shape adds low-end driveability.
- New exhaust pipe joint
seal.
- Exhaust flange bore shape
is now oval, which improves mid-range and top-end power delivery.
- Exhaust valve flaps add a
tuned, 2.5mm hole for improved bottom-end response.
- Redesigned exhaust
governor components provide added stroke adjustment.
- Ignition flywheel mass
increased by 8 percent to improve top-end over-rev character.
- Aluminum ACG cover is
redesigned for better sealing against water and mud.
- New lightweight drive
chain is 3 ounces lighter than the previous design.
- New heavier spring rates
in front fork combine with new damping force rates to produce
improved ride quality in varying riding conditions.
- New
anodized aluminum brake pistons and newly designed front brake
disc reduce unsprung weight by nearly 5 ounces in the front brake
system.
- New lightweight steering
stem features aluminum top threads and stem nut to reduce weight 2
ounces.
- New handlebar grips add
to rider comfort.
- New side panels feature
20 percent wider air intake openings for improved mid-range and
high-rpm throttle response and power.
- Optional 20-inch front
wheel improves cornering traction and rider comfort.
- Team Honda-inspired
colors and graphics.
Engine
- Liquid-cooled two-stroke
single-cylinder engine with 54mm x 54.5mm bore and stroke and
8.8:1 compression ratio.
- Nikasil-plated cylinder
reduces friction and heat to improve overall performance.
- Piston
ring groove is anodized for added durability.
- 36mm Mikuni TMX
flat-slide carburetor delivers improved bottom-end throttle
response and complements the RC valve's performance for improved
mid-to-high-rpm rideability.
- Carbon fiber reed-valve
petals enhance throttle response and engine performance.
- RC-style exhaust valve
features an NSR road racing-inspired rotary flap design that
provides smoother power transition between low- and mid-range
engine speeds.
- Expansion chamber design
enhances the engine's
power output and delivery.
- A 16-bit processor in the
ignition CPU produces faster data calculation and more accurate
ignition timing for the solid-state 3-D map-type digital ignition.
- Eight clutch plates
provide significant surface area to handle the engine's torque.
Clutch springs provide a light feel at the lever.
- Dual
radiators provide 21 percent more surface area and a 19 percent
improvement in heat dissipation over the previous single radiator.
- Steel water-pump gear and
steel kickstarter-shaft collar improve reliability.
- Five-speed close-ratio
transmission is durable, and combines with 13/52 final-drive
gearing to match the engine's power characteristics.
- Primary kickstarting
system allows starting in any gear.
Chassis Suspension
- Second-generation
twin-spar aluminum frame and swingarm offer an optimal
balance of rigidity and strength for light, easy handling on
widely varying track conditions.
- Frame features
lightweight twin-spar aluminum construction with
semi-double-cradle configuration.
- Extruded aluminum main
frame spars measuring 80mm x 30mm reduce torsional rigidity 25
percent and increase lateral rigidity 10 percent compared to the
first-generation design. The result provides an ideal balance of
rigidity, strength, compliance and comfort.
- Chassis design locates
frame spars lower for a narrower feel compared to first-generation
design.
- Forged aluminum steering
head provides a compact and extremely durable mount for the frame
spars and engine downtube.
- Semi-double-cradle design
features a single, large-diameter, 45mm x 50mm dual-box section
downtube. Two rugged box-section rails attach to the base of the
downtube and support the engine.
- Pro-Link?
single-shock rear suspension system features a
fully-adjustable Kayaba rear shock with 12.6 inches of travel and
separate low-speed (18 positions) and high-speed (2 turns)
compression damping adjusters. The adjusters are located together
in a concentric fashion, with a screw inside a nut.
- Inverted Kayaba cartridge
fork features improved
damping force transition characteristics. The design isolates
the fork oil and damper oil with an air/oil separator and a unique
rubber bladder lining inside the base of each fork leg to minimize
aeration-induced damping force losses.
- Inner
surface of fork's outer tubes is honed to retain a thin coating of
lubricating oil to reduce friction with fork bushings.
- Swingarm features a
dual-axis, double-taper design with a large cast aluminum
cross-member.
- Linkage mount on frame
cross-brace is raised to minimize ground contact on jump landings
and rough terrain.
- Rear axle diameter of
25mm and large-diameter bearings provide significant rigidity to
withstand tortuous track conditions.
- Compact dual-piston front
brake caliper with aluminum pistons reduces unsprung weight by 48
grams.
- Front
disc brake cover helps protect rotor and caliper from damage.
- Large, 240mm front and
rear brake rotors.
- Front wheel features
large-diameter front axle and wide wheel-bearing span for
additional rigidity.
- Lightweight hubs and
solid-section rims with strong straight-pull spokes offer a high
degree of durability and minimize unsprung weight.
Additional Features
- Slim design combines with
minimal bodywork to emphasize the beautiful frame and engine. Seat
design creates a narrow profile in the seat and tank area,
providing excellent comfort in competition riding.
- Fenders, shrouds and
sidecovers emphasize a clean, purposeful design.
- Seat cushion uses soft
foam and is positioned close to the fuel tank, providing a smooth
transition to increase rider mobility and comfort.
- Handlebar is
rubber-mounted to reduce rider fatigue and improve comfort.
- CR125/250 handlebar
holders provide three different mounting positions: standard
CR125R holder provides a 3mm rearward set and can be rotated 180
degrees to position handlebar 6mm forward. Optional CR250R holders
provides neutral position to match rider preference.
- 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.
- Lightweight, rugged chain
guide and lower chain roller for maximum durability.
- Comfortable, durable
controls and high-quality fasteners.
- Adjustable
front brake lever.
- Stainless steel clutch
cable for long life.
- Wide, cleated cast
stainless steel footpegs are self-cleaning, resist corrosion,
provide excellent grip and fold for extra ground clearance.
- Cleated rear brake pedal
and folding shift lever tip.
