SUZUKI REVEALS COMPLETE 2006 LINEUP
2006 SUZUKI RM-Z450
The RM-Z450’s entry into the world of 4-stroke motocross has met with great success. The RM-Z has established itself as the 4-stroke machine that handles like a nimble RM, but with the type of strong, tractable 4-stroke power that all riders appreciate. The RM-Z450 engine is based around an over-square bore x stroke design, with liquid-cooling, four titanium valves per cylinder and double overhead billet cams. Suzuki innovations include the Suzuki Advanced Sump System (SASS), which positions the crankshaft lower in the crankcase to reduce the center of gravity, and the Suzuki Active Vent System (SAVS), which reduces crankcase pressure. Super-accurate thin-wall aluminum-alloy castings for the cylinder head, cylinder and crankcase combine with magnesium-alloy cam, clutch and magneto covers to reduce weight. Plus, a 4-speed transmission with vertically-staggered transmission shafts reduces front-to-rear engine length.
The engine is housed by a lightweight, twin-spar frame combining aluminum forgings, extrusions and stampings welded into a single unit. The whole package is supported by a Showa inverted cartridge fork and Showa reservoir rear shock that includes a 4-turn range of high-speed compression damping. The RM-Z450 features a unique aluminum rear swingarm built using hydroformed, thick-wall tapered arms welded to a cast linkage bracket and forged axle holders.
The forged-aluminum link pivots on the swingarm itself, with a one-piece forged-aluminum link rod connected to the frame. The system ensures that the rear shock absorber moves in a smooth arc as it compresses, reducing side loads. Other features include specially-designed Bridgestone tires mounted on lightweight aluminum rims with a special spoke/nipple design, plus Renthal aluminum handlebars as standard equipment. The Ultimate Four-Stroke Weapon, Suzuki RM-Z450 – a lightweight, exciting package, combining 2-stroke RM size and feel with responsive four-stroke power and torque. The product of Genuine Suzuki Engineering.
