2004 Suzuki RM250Edit
The 2004 MY RM250 has received several revisions aimed at improving the power delivery. A lighter flat-top piston, redesigned exhaust ports, and piston rings have been used, and the carburetor was rejetted, also. At the same time the fork grew thicker, with new shocks and a new rear linkage for better progressive action.
Ergonomics have been tweaked, alongside the brakes, and the bike got a stronger frame and better clutch cable adjustment.
2006 Suzuki RM250Edit
The 2006 MY RM250 is a two-stroke quarter-liter dirt racing machine which has been used by Ricky Carmichael and he proved that it is indeed a champ's bike. Quick throttle response, amazing power and torque for riding hard and excellent damping capabilities, even when landing really tall jumps.
The engine and the frame of the bike have both been massively updated and provide more performance and reliability. The brakes and bars have also been updated for this model year. Maybe you won't become the next Carmichael, but at least you can give life your best shot.
2007 Suzuki RM250Edit
The 2007MY brings several updates for the Suzuki RM250. This quarter-liter dirt racer receives a redesigned seat with textured side panels for better grip, redesigned exhaust ports, revised engine placement inside the chassis, while the suspensions have also been tweaked and made lighter.
This quarter-liter 2-stroke is now more maneuverable thanks to the optimized mass distribution and you'll be able to get more from the 5-speed transmission whether you'll be riding fast and jumping mounds or drifting around corners.
2008 Suzuki RM250Edit
The 2008 RM250 is the epitome of power and racing spirit in the world of motocross competition bikes. Suzuki delivers a mean beast which can take almost any rider by surprise, as the brute power and explosive torque this two-stroke quarter-liter liquid-cooled single are something to be reckoned with.
This bike is a tough-as-nails engineering marvel and can also take a beating. The strong chassis is complemented by racing-grade Showa suspensions with enhanced adjustability, while the pegs and bars are also complying with the rigors of hard riding. Cue powerful hydraulic brakes, precise cornering and a narrow, easy-to-flip profile for the ultimate ride.
