according to dr pulley site catalogue
http://www.drpulley.info/drpulley_docs/Typenliste.pdf
the 2005 model has the size 26x13 and 21gms each x 8 rollers as standard if you want a more revy engine that pics up faster at lower speeds rather than just trying to use torque alone, and has the same top end speed, then 10 to 15% lower in dr pulley rollers is the norm.. if doing a lot of motorway miles then go for same weight rollers as this will decrease your engine revs at speed by about 500 rpm minimum and the general ride will stay the same.
so up to you either 18 gm dr pulleys

or 21 gm for motorway miles

+ postage as well..
