Didn't Yamaha run a v-twin in the Paris-Dakkar?
I thought it was a wr450f set up with front and rear drive.
There's nothing wrong with v twins in the dirt or belt drives though.
As long as the engineers designed the bike for what it's meant to do.
All Buell and any manufacturer is worried about is making $$ and selling a bike, not if they created the best dirtbike/streetbike/cruiser in the world. The consumer will determine if this bike was built/ designed correctly.
My money says they did.
