Suzukis new Motocrossers

Suzuki has made a name for themselves with their phenomenal handling characteristics the RM 125 and 250 are always one of if not the best handling bikes on the track. However with there sharp turning and handling they lose high-speed stability. This year they addressed this situation and set the bike up a little differently in hopes increasing the straight-line stability. In doing this they not only increased high-speed stability but they were able to keep for the most part, their great turning and handling abilities of the past. Suzuki held nothing back when it came to redesigning the new RM models they increased durability of the hardware and claimed to increase the life of the motors with crank changes. Suzuki has always been in the runnings for shear power but never seem to be the one on top. After spinning a few laps aboard the new Suzuki's this year may be a different story.2004 RM 125The new RM 125 has a very comfortable rider compartment and suits taller riders well. The motor on the RM 125 is also very impressive with good power thru out. Bottom end was a little weak but with just one tooth down on the rear sprocket the bike becomes much easier to keep in the meat of the power. The mid range power to top end rev is smooth and just keeps on pulling. The biggest up side to the power in the RM 125 is that the bike work well for beginners and pros with its broad power band. We tested the RM 125 at a very sandy track and its definitely a screamer. The suspension on the new RM is really balanced and once you get the adjustments dialed you begin to feel how stable the design is at speed.2004 RM 250If you have ever been to a MX national or Supercross you know the sound of a factory bike. On test days usually nobody gets in a hurry because of the fact that there is a long day of testing ahead. As the first bike hit the track and we heard the sound of the new RM it suddenly became a mad house as testers were scrambling to find out if the new RM 250s bite was as bad as bark. The 250 sounds mean and it puts out some serious boost. The RM 250 has tons of power from the crack of the throttle to the four stroke like top end the new RM is a power house to be dealt with in 04. The handling and suspension compliment the new motor with more high-speed stability and the same old turning abilities of the past.2004 Whats New RM 125Flat top piston (lighter) for more bottom power via closer squish area.
