If you find any dirt bike boring, you frankly don't love riding. That sort of "If I can't ride XYZ or I'll quit!" is lame. No offense of course! ;)

Are they actually calling this the KX450?  Its a KX450F.   A KX450 would be a fire breathing bad ass 2 stroke that would shred this turd into a thousand pieces of scrap metal.

I was expecting to come here to mock ktm riders ragging on another new bike that didn’t come with e-start or hydro clutch, but then they(kawi) surprised me and made me wrong.

good job Kawasaki!

i was also going to then say but trash can the air forks, but they did that too.

i wanted to talk trash but I can’t.

ahhh wait a minute, no wide ratio gearbox and enduro setup?? What gives.

but still, good job kawi:thumbsup:

whats more impressive, being able to tune my bike with a few hundred dollar computer, or being able to tune my bike with $2 in tools? Jk, FI is awesome too.
