hi ducvet. not done any multis but a heap of 1198 supers. most like the stock flywheel. my early experiments started with a machined aly wheel. full aly wheel. machined steel and full steel. most people, me included, liked the stocker. on the few multis ive ridden it didnt feel to me like i would like to lighten the wheel. my belief is the more toque the engine produces, the less it likes a light wheel. the wet really brings out the shortcomings of the lighter flywheel. my thoughts and experience only.
