2005 Suzuki RM-Z 450


Suzuki Motorcycles continued to make changes to the well-known RM line in 2005. These changes can be found in everything from the RM125 two stroke, to the RM-Z450 four-stroke, and all of these changes serve as benefits to the overall performance of the Suzuki off-road motorcycle line.

As popular two-stroke motorcycles were being phased out within the first ten years of the 21st century, more capable four-stroke options were presented to riders: this is the essential nature of the Suzuki RM-Z model line. It is encouraging to see a well-known, reliable Japanese manufacturer continue its pursuit of excellence, even within its most popular and best-selling models. The 2005 Suzuki RM-Z models were made more powerful and capable in the low-end RPM range, with a few simple engineering tweaks.

The 2005 Suzuki RM-Z is offered as a four-stroke, 250cc class motorcycle, as well as a 450cc class motorcycle. The 2005 Suzuki RM125 and RM250 two-stroke models are capable of holding their own against their larger, four-stroke family members. However, the lure of the four-stroke begins with much more RPM range and capability from bottom to top. Additionally, laws governing the prohibition of two-stroke motorcycles on public trails and public-use lands also provided motivation to take a more serious look at the four-stroke RM-Z options.

The 2005 Suzuki RM-Z250 runs strong on a 249cc, liquid cooled, single cylinder four-stroke. The five speed gear box offers plenty of run and RPM capability from top to bottom. When it comes to getting off the line and finding the power of the low-end torque, these bikes are hard to beat in overall performance. Throttle responsiveness of the 2005 RM-Z was the most impressive to date, and with the common performance modifications and tweaks to the carburetor, the modifications will open up even more engine potential.

Suzuki off-road motorcycles are well-known for their maneuverability, and expert handling. The enhanced suspension on the 2005 RM-Z allows better overall handling through increased damping efficiency, and performance quality. In the grand scheme of four-stroke motorcycles within its class, it is a true competitor with the Honda CRF250R.

The 2005 Suzuki RM-Z250 serves as an excellent option for riders of all shapes and sizes, though the 37.8 inch seat height may serve as a bit of an early challenge for some inexperienced, smaller riders. The capable power plant is more than sufficient for new riders, as well as those who have spent countless hours in the saddle. Possessing more low-end pull than its two-stroke brothers, the Suzuki RM-Z250 will serve as an asset for first-time track and trail riders. Off-road riding is as fun as it looks, but it takes a significant amount of coordination that professionals tend to be good at making look easy. Simply put, every rider will experience a learning curve; however, a tool such as the Suzuki RM-Z250 possesses impressive power through a simple operating platform, making the learning curve incredibly steep, and very enjoyable.
