Suzuki Dirt Bikes

In 1909 long before Suzuki dirt bikes came about, Michio Suzuki was making high quality weaving looms for the Japanese silk industry.

After some years the business branched out into automobiles because of growing consumer demand. This was short lived however when the government forced the company to cease production after deciding civilian cars were a non essential commodity.

After the end of the war in 1945, Suzuki resumed production of silk looms but also diversified into various other products such as musical instruments and agricultural machinery. Suzuki produced its first bicycle/motorbike hyrid called the ‘Power Free’ in 1951, a 36cc two stroke powered bike with pedals and a two speed transmission. The ‘Power Free’ was designed as an inexpensive form of transport for the Japanese people.

It was followed up by a 60cc version called the ‘Diamond Free’ which, with the ‘Power Free’, gained enormous popularity resulting in Suzuki producing 6000 bikes a month.

In 1954 Suzuki changed its name to Suzuki Motor Co. Ltd and motorcycle production ramped up with the forerunners of the Suzuki dirt bikes range being exported to America for the first time in 1963.

With the sport of motocross gaining popularity from the late 60’s, Suzuki dirt bikes cemented their dominance on the sport with a string of 500cc World MX championships during the early 70’s and continue to win titles all over the world.

’12 Suzuki Dirt Bikes


The RMZ450 is the leader of the Suzuki dirt bikes range and has undergone mainly minor updates for 2012. The engine compression ratio has been upped and the intake and exhaust settings revised to increase power whilst still staying within the 94db noise limit. The ECU settings has been revised as well to improve power delivery and to improve over-rev.

The 450 also has the added feature of interchangeable igniton couplers, stock, leaner, and richer, which can be used to change the power delivery of the engine.

The graphics are updated with a yellow/red/black scheme but the cosmetics of the bike are largely unchanged from last year, including those butt ugly brake rotors front and rear


The RMZ250 has also received the cosmetic updates for 2012 but has a host of engine updates and revisions. These include changes to the exhaust length, exhaust and intake cam timing and revised settings in the ECU, all to improve power, throttle response, over-rev and still keep within the 94db noise limit.


The RM85 is the junior entrant in the Suzuki dirt bikes stable and is pretty much unchanged for 2012. It’s still available in the standard configuration and also the big wheel model which has 19 inch front and 16 inch rear wheels for larger riders who are making the transition to a larger bike on their way out of the junior ranks.
