2007 Suzuki RM-Z250
2007 RM-Z250
The 2007 RM-Z250 is all new from the ground up and it is 100% Suzuki. The RM-Z250 features a compact, lightweight and powerful 250cc 4-stroke engine design, a strong and lightweight aluminum chassis, Showa suspension components and many high-performance features for the ultimate 250cc 4-stroke racing machine.
The RM-Z250 engine is based around an over-square bore x stroke design, with liquid-cooling, titanium valves and double overhead billet cams. The engine is housed by a lightweight, twin-spar aluminum-alloy frame combining aluminum forgings, extrusions and stampings welded into a single unit. The whole package is supported by a Showa inverted, twin-chamber, cartridge fork and Showa remote reservoir rear shock. The RM-Z250 features a unique aluminum rear swingarm built using hydro-formed, thick-wall tapered arms welded to a cast linkage bracket and forged axle holders.
Other features include Dunlop tires mounted on lightweight aluminum rims with a special spoke/nipple design, plus Renthal aluminum handlebars as standard equipment. Included with this year's new model are all the benefits of Suzuki's race contingency, trackside support, Tony D School and Good scholar program. All these added benefits are exclusive to Suzuki riders.
The RM-Z250 for 2006: it's taking the four-stroke world by storm!
