The Thunderbolt has the inverted fork's right? I f so give these sites a shot.http://www.dkf-perf.com/n5100.htm
Cap can build the bracket for the Nissin so you can run dual discs cheaply. You will have to run a Buell rotor reversed on the left side. He can also do a mirror image of the rotor carrier to make it look right but that drives the cost up. With dual 6 piston Nissin calipers you will need a 9/16 bore MC and a dual disc hose. This method is the cheapest way but will still cost in the $500-600 range with all the parts needed. If interested in a dual disc setup, give Cap a call at 865-546-3380 and he will point out all of the options and costs. Found this on the X1 files good luck:thumb:
