OK,no I dont think in a short drag race any thing is faster or accelerates as fast.But as far as top speed heres some averages in a test a few years ago..Husaberg 650-103.6mph...KX500-107.6mph...KTM 540(big bore kit,other bikes had mods to)-109.1mph...Honda XR650-112.0mph.These were averages,on one run the XR got 122.0mph!This was on a dry lake bed and wind was a facter,but theser were the results they had.But for brute acceleration Id say the KX is KING!
