In 2007, at Moto-industry hotspot Pole Position Raceway in Corona, California, Suzuki hold a private media event where they introduced the RM-Z250, a motocross motorcycle engineered to win, with newly developed features.
The 2007 model shared the improvements with its bigger sibling, so the ride provided a better overall experience thanks to the updated engine, chassis, suspension, and redesigned swingarm.
The 250cc engine that came at the center of the bike featured revised combustion chambers and achieved a boost of torque and power in the mid-high rpm range. The 2007 Suzuki RM-Z250 had its heartbeat set by a 249cc four-stroke single-cylinder liquid-cooled engine with a power output of 44 hp at 11,000 rpm and 30 Nm (22 lb-ft) of torque with a peak at 8,500 rpm.
The model featured a chassis composed of a rigid twin-beam aluminum frame, and for enhanced suspension performance, the bike adopted KYB rear shocks. Also, the bike came with some trick features, such as oversized Renthal handlebars and a seat with much more grip, as well as redesigned ergonomics which created a more comfortable riding position that reduces fatigue.
For suspension, the bike packed a cartridge-type telescopic Showa fork on the front with 300 mm of wheel travel and a fully adjustable suspension with 310 mm of wheel travel on the rear wheel.
