Hi, I'm considering replacing the standard flywheel on my Roadsport (150 Sigma) for a lightened alternative and would be interested in hearing any views - positive and/or negative - about this conversion. I know that it should make it easier to reach maximum revs, but on the down side, make it more 'fiddly' in traffic - especially as I have throttle bodies fitted. Is it worth the pain for the return??. Many thanks, Keith
