after lots of wondering what bike to get next ( the spain tour killed me on the storm

ive decided to put a straight bar conversion on the storm along with some better front brakes as the stock ones just wasnt up to the job in spain !
this will be a christmas project so im just looking around and costing up at the moment, anyone know whats a direct bolt on upgrade? including radial mc?
iirc someone used to sell upgrade units on here but i cant remember who lol
oooh and i have been thinking about altering a tank to get a few extra litres in as fuel stops were a pain
