About 10kg in fact

And it's not over the front axle either!

Bargain then!!

You can run that amount of oil with the dry sump set up, helps with cooling. Interesting to see they dropped the crank stroke to 85mm?

[Error404]

I guess to increase the rod ratio for higher RPM use?

I see what your saying but if your going to make a change to chase more revs you would at least make it a square engine with bore and stroke. Changing by 1mm seems pointless? Perhaps the bore was at its smallest to fit the valves in?
