08 Suzuki Dirt Bikes ReviewedThe RMZ450 is the flagship of the 08 Suzuki dirt bikes and the big news this year is the introduction of fuel injection. The system has been in place on the R450 quad for a couple of years but has now been fitted to the RMZ. The throttle response is much improved due to the fuel injection and should prove to be a lot less maintenance and tuning compared to a carburetor. There is a smaller capacity aluminium fuel tank fitted because the injection system is more fuel efficient, the tank also houses the electric fuel pump. The '08 450 finally has a five speed transmission and there's been work done on the frame to allow it to flex more but also increase strength. Both the RMZ450 and RMZ250 have wave style brake rotors for improved braking in wet, muddy conditions.
RMZ250 The RMZ250 has new footpegs this year, designed to prevent mud build up between the mounting bracket and the footrest. There's also a new gripper seat fitted and the hot start lever has been moved to the right hand side of the handlebars, as has also been done on the 450. There's not a whole lot else that's new, the exhaust port shape has been modified to improve mid to high range output and the piston profile has been changed to increase reliability. The frame has been modified to improve rigidity and the Showa rear shock has also been updated.
RM250 The two stroke 250 is just marking time for '08, there's not much in the way of updates or improvements but the RM is still a proven performer.
The baby of the Suzuki motocrossers is now available in a larger configuration as well in '08, it has bigger wheels and a longer wheelbase for larger juniors. The frame has been improved offering greater rigidity and the chain adjustment system is styled on the RM250. The 85's have a twin pot brake caliper up front with a 220mm diameter rotor and a 200mm rotor at the rear. Most of the development has gone into the four stroke Suzuki dirt bikes for this year with the two strokes receiving mainly cosmetic updates.
