Darkside refers to fitting a car tyre to the bike, 26 PSI allows the tyre to flex on cornering, but the stiffer side walls still support the bike.

Was 26psi recommended for "bike only"...and what brand/model/size of tyre is he talking about, and why not 24psi or 28psi??

I have a mate who has gone "Darkside" on his Suzuki Boulevard 109 Cruiser.    Simple experience has shown that 26 psi works best.   Higher than 26 and the tyre wall does not flex enough, and the flat contact area profile tries to lift the bike as it turns, which strongly resists the turn.   Less than 26psi and side wall flex is excessive and the tyre looses too much shape across the flat contact patch.    I have followed him closely through some twisties to watch his rear tyre, and could see that in the turns the side wall would flex, and about 75% of the "flat" contact patch of the tyre remained in contact with the road.

Cost caving was huge, as the Boulevard rear is over $600, and a Commodore size radial cost him $120.

Hi JC,  I previously posted some of the info you were asking about.  Check out this link.  http://ozstoc.com/index.php?topic=9271.0
It has the details of the tyre I purchased and some great video's that Diesel posted re darksiding.

I am happy to answer any questions but on the 30th I am off to Dubai again and will be away for a month.  I am not sure how much time I will be spending online while over there.
