The KTM EXC-Fs are 35 HP, 240 lbs. for the 350 & 58 HP and 250 lbs. for the 500. It seems reasonable that the new clean sheet counterbalanced liquid cooled EFI'd RE 450 LC will hit 40 HP and 300 lbs. That gives RE 50 pounds of mass to save money on materials with, and only getting about 2/3rds the HP of the KTM seems doable by many clever EFI tuners here. If they can do this for about $5500 vs. the $11K to $14K for the KTM they'll fly off of the shelves. A 300 lb. "Supermotard-ish Scram" street variant would make a very nice street bike.
