2006 Suzuki RM Review


Those shopping for the Suzuki RM125 in late 2005 and during the production year of 2006, realized they were shopping for a dying breed. While the performance of single-cylinder, two-stroke motorcycles will long be desired, new laws (especially in beloved motocross states such as California) were red-tagging these capable bikes because of emissions controls. Regardless of impending laws, Suzuki offered its popular RM125 in 2006, even making changes to make the bike a more capable track and cross country performer. Suzuki also continued to manufacture the impressive RM250 two-stroke in 2006.

The Suzuki 2006 RM125 remains an excellent motorcycle for riding in the dirt, on the sand, cross-country, on farms, or even for tooling around pit and infield areas of racing facilities. For anyone who has ever straddled the Suzuki RM125, the 2006 model upped the ante of its predecessors. With the few engine changes, the RM125 became more of a competitor with the Yamaha YZ125 and the KTM 125SX.

For those hoping to find powerful low-end torque and two-stroke engine performance that can rival that of the 250cc, four-stroke engines those desires should be quickly set aside. Slight changes to the Suzuki RM haven""t made this machine a super-cycle by any stretch of the imagination; however, when running it wide open at high RPMs, this bike is a joy to ride. It is well-balanced once the rubber leaves mother Earth, and it may even be more comfortable in the air, than it is in the dirt.

In terms of handling and maneuverability, the 2006 Suzuki RM is precisely what one would expect from a Suzuki motocross model. It corners like a dream, and is exceptionally responsive to riding on or off the track. At high speeds, like most Suzuki models, it tends to glide laterally, regardless of being held on a straight line. This phenomenon is really the only weakness of Suzuki motorcycles. With regard to durability, riders will never hit the trail or track worrying about anything but the path in front of them and the riders behind them.

The 2006 Suzuki RM125 is an excellent bike for new riders, especially those who are of adult age, and they are full grown in nature. It""s a graduated ride from the Suzuki JR90 and performs similarly to the RM-Z 250 four-stroke. For those who want everything Suzuki has to offer in the realm of two-stroke motocross bikes, the 2006 RM250 will quickly convince you to purchase adequate amounts of safety equipment to enjoyably pin the throttle for one of the most impressive off-road rides created in the first decade of the 21st century. All in all, the 2006 Suzuki RM models will offer plenty of smiles and more than a few exclamatory shouts of airborne joy.
