I don't think this machine would be eligible for Marathon in any event- looking at an older rulebook but:

When I studied the book in depth, Marathon has become largely irrelevant to anything but the KTM 450RR- you're not allowed to change anything from standard (down to handlebars), meaning there's only one machine that is capable box stock.
I think they've made the category largely irrelevant, but what do I know.
Long rod motors are cool. The longer rod means a longer dwell time, which can really change (and increase) power characteristics. With that said, that's a pretty darn oversquare motor!
One last thought- the Dakar has become increasingly technical in years past, and I think that trend will continue. Do you think the LC4 based machine (with higher weight than a comparable converted enduro bike) will be a disadvantage in that light?
