Dirt Bikes Review: Evolution, Part - 1

Dirt Bikes Review: Part – 1, the evolution of Kawasaki motor company’s dirt bikes. The Kawasaki motor company’s first production dirt bike produced in 1963 - the B8m Moto crosser was a racing machine that won the majority of motocross races in Japan at that time. Kawasaki’s legacy started with the B8m Moto crosser and the long running KX motocross series stemmed from these early bike races. The KDX series bikes from Kawasaki were more suited to cross county and enduro racing. However, because of new emission laws these 2-stroke bikes were on their way out and 4-stroke dirt bikes such as the KX250F and KX450F were developed. The KX250F has some updates for 09’ such as: the carburetor and ignition settings have been revised to improve low end power, the transmission has new thicker gears to improve strength and reliability, titanium foot pegs and mounting brackets and an assortment of aluminum components instead of steel to reduce weight, the aluminum skid plate and renthal bars are standard. The KX450F dirt bike has a new redesigned cylinder head with revised exhaust and inlet ports, fuel injection and a new piston, all of which has made the engine much smaller and lighter. The KX450F has a reworked frame and the main spars being smaller making the frame narrower but slightly thicker down beside the rider’s ankles for improved control and feel over the bike. The swing arm has a different profile and mounts higher in the frame, also the sub-frame has been redesigned, and it’s narrower and stronger. The aluminum skid plate is also standard on the KX450F. Both the KX250F and the KX450F have Black anodized rims. The majority of updates for Kawasaki dirt bikes of 09’ appears to be mainly on the four strokes and the 2-stroke bikes receiving cosmetic updates.
