Stefan Merriman's 2013 WR450F race bike

"For events held entirely in these trickier conditions, a heavier flywheel weight is used to help the rear Dunlop find traction."

 

So much for reducing reciprocating mass to make the bike feel lighter !

 

Flywheel weight is only part of the equation there. The piston, con rod and crank all play a part as well. Bigger displacement means more weight for all those components, and more reciprocating mass affecting handling.

You would probably have to get rid of the battery to run that lower subframe?  That ECU looks cool too, I never seen that one before.

Midlifecrisisguy doesn't have a battery/starter/etc... he might be able to do it.

I've seen Stefan race Six Days before. It's insane what he and the other top Euros can do on a bike in the nastiest conditions that are nearly impossible to walk let alone race on. That bike is awesome!
