Suzuki RM-Z450 2009 ,Our testers all noted the Suzuki's cornering ability, though some praised it higher than others. The aggressive entry was met with mixed reviews. Showa and Suzuki have a good working relationship. Suspension was suitable for our wide range of physical size and riding ability.The smooth, usable power puts down fast lap times, but of the EFI trio, the RM-Z is the most difficult to get startedErgonomics are comfortable and allow riders to take full advantage of the aggressive chassis. While we were all impressed with the Suzuki’s engine performance out on track, in the pits it isn’t the easiest to start. Two kicks minimum. And sometimes three or four kicks are required if you don’t have the piston at TDC. And despite the RM-Z being endowed with EFI, it still employs a carburetor-like fast idle/choke switch on the throttle body as well as a hot start, whereas the Honda and Kawasaki do away with both. Problems with Suzuki’s drivetrain were few and far between. Although Minor claimed that the bike popped out of out gear once or twice, other test riders never encountered such a problem and we’re more than pleased with its versatile gearing and light and progressive-feeling clutch.Another plus was the RM-Z’s narrow seat, Pro Taper handlebars, and extra-wide footpegs, combining for a very intuitive riding position. Controls and levers are placed at a natural distance for all of our vastly different sized riders and help promote confidence allowing the rider to extract full performance out of its sharp chassis.
