With the creation of Kawasaki KX450F, Japanese engineering concern has the potential to pick up the palm among the most a
ggressive and dynamic crossover from motorcycles companies of Austria (the creators of the line motocross and enduro motorcycle KTM).
A few years ago Japanese manufactures start with the replacement of steel frames on their bikes to aluminum. Next in line were engines - or rather, the power system. We are talking about the appearance of motocross bikes with electronic fuel injection, and a pioneer in the use of injection systems in 2008 was the Suzuki RM-Z450. The electronic fuel injection has several advantages: it reduces fuel consumption, which in turn allows the fuel tank to have a smaller volume at the same time reducing the weight of the bike. Modern motocross bike has more than one such interlocking chain, dramatically improves performance. This and more timely response to the motion of the handle, "natural gas", and the possibility of immediate change system settings, food, and much more interesting and useful.
Although outwardly the new Kawasaki KX450F similar to its predecessor, 2009 release, but "inside" the differences are significant. If we talk about the specifications, then the last engine was good, but the current exceeds all praise and expectations. Capacity of the new engine more than anything in 1.4 liters. force, but it is uniformly distributed over the entire operating range, which reaches a record high for its class up to 11,000 rev / min. At 8900 rev / min maximum output grew from 52.33 to 53.76 l l.sil. forces. The engine has a new crankshaft, lightweight piston and modified the intake phase, larger radiators were cooling, increased housing, an improved design was clutch. The truth just as stretched as in the previous model, still transfer, but the power increase more than offset this disadvantage.New Kawasaki KX450F 2010 year included injection DFI (Digital Fuel Injection), automatically adjusted under climatic or weather conditions. The new injector is able to dispense with battery.
At first, and not just glance, Kawasaki KX450F 2010 has a pretty standard size and weight, but really it is heavier machines in its class, including such monster as the KTM SX450F, and together with the battery and starter.
