The first thing you should remember when throwing a leg over a RM-series bike is that these machines mean business. They are engineered for top performance and it's not seldom when you see them on the podium. Don't be fooled by the small displacement of the 2005 MY RM125, as the 2-stroke engine is punchier than you'd expect maybe, and a jerk of the throttle could easily send you into a wheelie.
Because of the high-performance goal Suzuki had for the RM125, the engine is liqud-cooled, but this doesn't seem to add too much bulk, as the bike is still very light, as any racing machine should be. Add in adjustable suspensions, 21-19 wheels and powerful disc brakes and be ready for pro-class fun.
