I fitted Sun-Risers last year. Initially I thought they were ace but....... I didn't like the idea of using epoxy resin to 'fix' my 'adjustable' bars for which I paid a handsome sum. The whole reason for fitting adjustables to my mind is to , well, adjust them as and when you please.
After about six months the fit of the clamps became slack, eventually failing under load! Luckily I was only wheeling the machine out of the garage.
Eventually went for an SV-N top yoke conversion which I find excellent.
You pays your money and takes your choice........choose wisely
