I doubt it. Sadly it seems people want more range and more torque. Luckily the newer gen of batteries and motors are GENERALLY a touch lighter, but the KSL is a big bike with a generally more complicated suspension platform.
Personally I if one finds 35NM not enough, which is already saving me 1/4-1/2 climb time, then we really are moving towards just spinning away... I would however like the newer generation of batteries for even lighter weight, same range.
Agreed, i never found the power to be a issue. The noise however was a deal breaker for me, i love a quieter motor and the 1.1 is one of the loudest.
