I own a 2011 triumph storm. I have been doing some customizing to make it my own. I am looking for new grips and have found a style i like but am unsure of what size to purchase. anyone know what size the stock grips are for the storm? Question two... I have been considering buying the dart manta screen any thoughts? is or has anyone added one to their bike? just to give you som background i am running short tors without the cat. a power commander V, the entire exhaust system heat shields inluded have been ceramic coated black and all the controls and pegs have been podercoated gloss black. and just put triumph aftermarket black mirrors. slowly but surely the chrome is going away.
