I have tried to tell the RM 250 and RMX 250 model histories on this page as I know them. This page is still under construction. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

Suzuki introduced the RM series of motocross models in 1975, ”RM” standing for Racing Model”. The range quicly stretched out from 50 to 400cc and became very successful. A few years later the Full Floater swingarm was introduced and water-cooled engines came along in the early 80's — and the developement of the RM models continues even today. The ”Full Floater”mono shock system was introduced by Suzuki to all full-size bikes (125cc, 250cc and 465cc) starting in 1981. Suzuki first used liquid cooling on the RM125 in 1981. The RM250 was liquid cooled starting in 1982. The RM465/RM500 was never liquid-cooled. The first liquid cooled RMs, the 1981 RM125 and 1982 RM250, are by some people considered two of the finest MX bikes ever made. Both are in the Dirt Bike magazine's ”Hall of Fame” and recently Motocross Action magazine said that the 1981 RM125 was perhaps one of the best MX bikes of the last 25 years.

With the '83 RM250, fork diameter was increased to 43mm. Engine changes included a different cylinder head (revised squish band), and increased crankshaft inertia. Unfortunately, these changes were a step backwards as the '82 had a more potent powerband. Minor cosmetic changes were the only visable differences.

”George Jobé RM83 replica. New, stronger engine. New Power Reed system that gives even more power at low- and mid-range. 20% stronger gearbox. New improved frame. Improved Full Floater suspension. New tough World Championship design with the front end of the saddle above the fuel tank.” That's what a Swedish magazine ad told us about the new model.

Suzuki announces that they use their own SBC (Suzuki Boron Composite) coating on the RM250 engine. It is lighter than normal metal and radiates heath more easily. The more obvious improvement is more noticeable. For the first time, the RM250 has disc brakes both front and rear. The maximum power output is slightly over 50 horsepower. Also, the '86 RM250G had a new and stronger frame. Suzuki says that the amount of frame parts has been decreased to less than half. The Full Floater rear suspension was new, both swing and the link system."An eccentric cam in the link system for increased progressiveness and improved damping. Lower seat height despite of the higher ground clearance.” The engine was coated Blue.

Redesigned and lighter flat-top piston, redesigned exhaust ports and piston ringsare some of the other improvements to the engine. The carburetor has been rejetted. The frame, suspension and brakes have all been improved for the K4 model. Both front and rear shock absorbers are new, the rear suspension linkage has been redesigned for better progressivity, both front and rear brakes have been improved and the front fork is thicker and the outer fork tube longer than in the previous model. The frame has the same design than before but is made a bit stronger. Some minor improvements on the rear wheel and clutch cabel adjustement. The footpegs have been moved 10mm (0.4 in) backwards, the handlebar 7mm (0.3 in) and the seat has been redesigned and is made 10mm (0.4 in) lower than in the previous year's model.

2006 Suzuki year code: K6

The 2006 Suzuki RM250 recerived engine refinements that center around improved power/torque delivery and improved low rpm power, plus chassis updates aimed at better cornering and straight line performance. Also new for 2006 is the RM250Z, a limited edition RM250 with special Team Makita Suzuki graphics, gold-colored wheels and a black seat similar to Ricky Carmichael's championship-winning bike. Updates to the 2006 RM250 include the following: Engine updates: Redesigned cylinder exhaust ports to improve roll-on acceleration at very low rpm, power output at low-to-mid rpm and higher torque feel from mid-to-high rpm (exhaust port timing advanced, Sub-exhaust port timing advanced and port shape revised for optimum flow), Revised exhaust valve system for improved roll-on acceleration, increased power at all rpm levels with increased torque at low rpm (tip of main exhaust valve reshaped to delay exhaust port timing, redesigned side exhaust valve cam for improved valve sealing, improved side exhaust valve cam rod, main exhaust valve arm and linkage), Shorter intake pipe for improved low rpm engine response, New carbon fiber reed valve to improve low rpm engine response, Increased clearance between the crankshaft and crankcase to change the primary compression ratio and improve mid-range rpm torque and controllability, Increased clutch durability with redesigned plates and more durable clutch housing, Revised ignition map for increased low rpm engine response Chassis updates: Renthal tapered aluminum handlebars with Renthal-labeled handlebar pad – lighter than standard bars – rubber-mounted to reduce vibration New frame with reinforced tank rail, reinforced lower engine bracket, plus head pipe relocated 5mm rearward for increased straight line stability, Updated swingarm design featuring increased main beam height dimension for more rigidity and improved straight line performance, New front fork and rear shock settings for improved cornering and straight line performance, Improved front fork with emphasis on better cornering and straight line performance (increased slide pipe thickness for improved overall chassis balance and smoother mid-stroke movement, revised compression and rebound damping valve settings for smoother mid-stroke movement and better overall suspension balance), New handlebar mount for Renthal handlebars, Improved rear shock performance with emphasis on better cornering and straight line performance (revised compression and rebound damping valve settings for smoother mid-stroke movement and better overall suspension balance, revised spring rate for better overall chassis balance), New hex-head-style rear brake rotor mounting bolts for easier brake disc maintenance, New rear brake pad material for increased braking performance and improved rider feedback
