Jeepers, 64 HP? that is pretty good....even stock it produces the most of any 2018 bike (according to their dyno). Still $4k a lot to fork out for that 64 HP!

4k to gain 6hp out of a 450 seems excessive. If it was a 125 maybe fair but for a friggin 450 thats a ton. Ktm 350 can gain nearly 10 hp with cams, ignition and race gas.

The newest 350's are monsters and are extremely under estimated by people.

The DCR Cam, ignition, and race gas package makes 63hp. I don't think it would be far fetched to make 65+ with a high comp piston a some head work.

I don't care what the final numbers are, what did it start out at on his dyno? That's the real story.

Thats what im saying! that pc package for 4k is laughable to gain 6hp from a friggin 450.

Sure, its a pretty modded engine at that point, but is it like a 250 that has its neck wrung out? Reliability problems and rebuilds galore?

cams ignition and fuel isnt very much. DIdnt go to a super high compression piston or any porting. Thats a pretty mild set up in all reality... even stock exhaust
