2010 Suzuki RMX Review


The all-new enduro bike is getting rave reviews from all who've ridden it. From its new fuel injection, right down to the new suspension, the conversion from motocross to enduro has made everyone happy. This year's Suzuki body plastic color scheme is the basic solid black and champion yellow. At 32.7 inches wide and a seat height of 37 inches, with wider mounted footpegs, this bike is comfortable to most heights of riders without any adjustments.

Weighing in at more than every bike in its class, at almost 273 pounds (up from last year's 260, due to the new throttle body injection) one would expect to feel the weight in the handling, but not with this bike. If anything it's better. The only time you feel its weight is in heavy braking or steep hills, the rest of the time performance is right-on, so the rider feels like he's in control of a much lighter biker.

The suspension makes the ride perfect; the front fork is a SHOWA oil dampening telescoping fork with pneumatic shock, while the rear is a SHOWA piggyback reservoir type shock, with two-way adjustable dampening. This combo, sitting on Suzuki's aluminum frame makes a killer pairing. Tight in the turns, soft on the landings and with very little additional suspension work almost makes this an out-of-the-crate enduro winner.

The change from motocross to enduro was aided by the addition of lighting, instrumentation and different electronics. The bike comes equipped with a magneto-generator that powers the lights, instrumentation and fuel injection. It also has a battery; the battery is there essentially to power the computer brain. Once the bike is started though, the battery can even be disconnected and still run fine. It does comes with both an electric and kick starter.

The instrumentation is simple, as you would expect from an enduro, but nicer than many in its class. The LCD instrument cluster comes with both a standard and a sport mode; the first displays your speed, time, two trip lengths, and voltage. The other has a trip, an average speed, a lap timer, a trip computer and a low-fuel warning light. The warning light is sorely needed, since Suzuki did not increase fuel capacity, instead choosing to keep the aluminum 1.6 gallon tank. The fuel pump and sending unit also take up a portion of that tank, so that 1.6 gallons really doesn't get you all that far. With an enduro bike, a bigger tank certainly would have been a nice addition.

The all-new, five-speed constant mesh transmission has wider gear ratios than its motocross counterpart, the RMZ. Both the engine and transmission have a new skid plate to protect them, even though ground clearance is excellent at a little over 12.5 inches. The liquid-cooled 449 cc, dual overhead cam, four-valve engine spews out plenty of power to match that transmission, making it fast on the runs and go all-out up the hills.

Suzuki has hit this one right off the track with its power and performance. It needs very little fine tuning to move it into first place with most riders.
