First Look–The 2003 Suzuki RMs!

UPDATED MODEL: 2003 SUZUKI RM125

The 2003 RM125 is the latest version of the racebike that made Travis Pastrana famous, with a broader powerband and better throttle response, producing significantly more power and torque between 6,000 and 8,000 rpm with no loss of high-rpm performance. That translates into better lap times with quicker acceleration and better rear-wheel traction creating the perfect motocross weapon for ’03.

The 2003 RM125 features many new updates aimed at improving the already potent RM125 and when combined with the $3 million dollars of available contingency, the RM125 becomes an unbeatable value from the showroom directly to the racetrack.Improvements to the 2003 RM125 include:

ENGINE

-New exhaust valve linkage system provides more precise, linearopening of the exhaust valves for improved power delivery andthrottle response at all rpm.

-Reshaped exhaust valves with new oval cross-section forbetter exhaust port seal and improved low-to-mid rpm power output.

-Improved airbox design features a new front cover to block engineheat and is fed by frame cover-mounted cool-air ducts for improved throttle response.

-More precise shifting transmission features a new shift paw) pin with reduced side play, a press-fit gearshift stopper pin and a more durable shiftcam stopper spring.

-Improved engine cooling with 10% larger radiator (same size as RM250).

CHASSIS

– Improved front fork response at mid stoke with the following changes:

– Heavier rate springs (0.40 to 0.42) to permit use of less compression damping

– Smaller diameter compression valves for improved response over small bumps

– Reduced front fork weight and improved durability with the following changes:

– New lighter weight aluminum cartridge rod and pipe nut

– More durable steel spring guide bushing

– Fork cap head is now hexagonal-shape and can be removed with conventional wrench to simplify maintenance

– Improved rear shock performance with following changes:

– Revised rebound damping control with new internal rebound spring and check valves for improved mid-stroke and low-speed response

– Improved rear shock durability with the following changes:

– Hardened piston shaft

– Reservoir cap head is now hexagonal-shape and can be removed with conventional wrench to simplify maintenance

– Wider footpegs with improved mounting position.

– Lighter-weight brake pedal with repositioned pivot for increased ground clearance.

– Modified sub-frame with round cross brace for improved airflow to airbox.

– More durable front wheel rim with thicker material at center and edges.

– New front wheel spacer for easier wheel installation.

– New brake discs with new hole pattern to reduce noise and pad wear.

– New rear brake pads with improved stopping performance and durability.

– Improved seat with firmer cushion, thicker and more durable cover and revised shape for better riding position.

2003 SUZUKI RM250

The key to a better lap time around a motocross track is making the motorcycle do exactly what the rider wants, when the rider wants, in the way the rider wants. A big part of that is tractability and traction, which comes from smoother throttle response and better low and mid-range torque. Which is why Suzuki engineers worked hard to improve the’03 RM250 in everyway.

The 2003 RM250 has been updated and improved in the engine as well as the chassis, making the RM250 better than ever. Add to this the over $3 million dollars in contingency dollars available and the new RM250 clearly becomes the class leader in 250cc motocross competition. Improvemments for the 2003 RM250 include:

ENGINE- Larger, reshaped exhaust port and sub-exhaust ports for increased low-to-mid rpm power and torque.

– Reshaped intake port plus revised scavenging port timing and shape for improved low-to-mid rpm power delivery.

– Narrower reed valve intake passage and matching intake pipe for increased intake velocity, improved cylinder charging and combustion.

– New exhaust valve linkage system provides more positive opening of the main exhaust valve for improved power delivery and throttle response at all rpm.

– Cam-operated sub-exhaust port valve system further enhances power delivery and rev capability from mid-to-high rpm.

– New domed piston with reshaped skirt for improved durability and throttle response.

– Larger airbox with 20% more capacity features a new front cover to block engine heat and is fed by frame cover-mounted cool-air ducts for improved throttle response.

– New exhaust system with thinner-walled construction to reduce weight – dimensions modified to enhance cylinder porting changes.

– Heavier magneto rotor increases crankshaft inertia for improved tractability and traction under acceleration.

– Smaller diameter right-side crankshaft end and oil seal reduces seal contact area and friction by 40%.

– New water pump impeller features improved blade shape for less mechanical loss and smaller diameter oil seal for reduced friction.

– More precise shifting transmission features new output shaft with improved spline shape, new shift pawl pin with reduced side play, and more durable clutch plates with lighter springs for better clutch lever feel.

CHASSIS

– Improved front fork featuring new damping piston with straighter oil flow passageways for more linear damping and new rubber bump-stop to minimize harshness at full compression.

– New rear shock with improved low-speed compression damping control.

– Wider footpegs with improved mounting position.

– Lighter-weight brake pedal with repositioned pivot for increased ground clearance.

– Modified sub-frame with round cross brace for improved flow to airbox.

– More durable front wheel rim with thicker material at center and edges.

– New front wheel spacer for easier wheel installation.

– New brake discs with new hole pattern to reduce noise and pad wear.

– New rear brake pads with improved stopping performance and durability.

– Improved seat with firmer cushion, and thicker, more durable cover.
