I don't think you are being negative, I agree with you. The bike comes with a single can system (albeit with two vents) and it is heavy.

I too would like to know the benefits of a dual can system on a bike over a single can system.

I appriciate the difficulties in producing a single can for the Tenere (in that it's a fairly short can)

I would like to see something of the science and engineering that suports the use of two cans over one.

A single can system would certainly be on my shopping list, as long as it was value for money.
