2015 Kawasaki KX450F First Ride Photo Gallery
Kawasaki has made another major leap in the evolution of 450cc motocross bikes with the new 2015 KX450F.
Kawasaki updates its flagship MX platform for 2015, see how the motocrosser stacks up in the 2015 Kawasaki KX450F First Ride photo gallery. Read a full review of the new machine in the
2015 Kawasaki KX450F First Ride
Kawasaki includes suspension, braking, engine and ECU updates on the 2015 KX450F.
Power is improved in the mid-range on the 2015 KX450F thanks to a new Bridge Box piston.
Perhaps the most impressive aspect right off the bat was the fork’s bottoming resistance on flat landings or when over jumping.
Kawasaki introduces the all-new Showa SFF-Air TAC Fork with Triple Air Chamber on the 2015 KX450F.
The left side handles all of the valving, compression, and rebound damping while the right side with the air serves as the sprung or resistance fork leg, although there is no actual spring.
The main upper chamber handles the majority of the work, with a stock 145psi setting while a narrower outer chamber rests much lower at 7.25psi.
The main upper chamber and narrower outer chamber are kept in "harmony" by the lower balance chamber (integrated into the fork lug), which is set at 130psi.
In order to hit those turns properly, a bike needs good brakes.
With the KX’s new oversized front rotor, braking is not a problem. Both the 270mm front and 240mm rear discs now have a more aggressive wave design that both increases friction and cooling.
The rear shock is a new Showa unit with revised valving, a Kashima coated inner body and an optional longer tie rod that lowers the seat height by 4mm.
When throwing a leg over the KX450F you immediately notice the comfortable ergonomics and spacious cockpit.
Other minor changes include a lighter rear subframe and lighter front and rear axles.
In the air the Kawasaki is balanced, and while it feels a bit on the heavy side at times, this is partially due to the larger layout of the frame and ergonomics.
Overall, the Kawasaki’s KX450F is looking very strong for 2015.
The green beast will not turn on a dime, but it also will not understeer and try to climb out of a rut.
Outside extremely tight turns, you will rarely find yourself more comfortable on a motocross bike.
If you were a fan of the KX450F, you can only expect improvements on what was already a very strong package.
