[Biker1234]

bore kit.jpgHi ,new to the forum just looking for advise really.I have a 2007 superbyke RMR 125 which I have built back up from nothing done a lot of mods to the bike from fitting a DEP S3 exhaust can to installing a bigger main carb jet,race cdi,air filter mod,alarm imobaliser and fitting a sound system on the bike too and mini carbon indicators front and back! Most recent upgrade was installing a digital speedo with rpm metre and lap timing which looks pretty cool now I'm after a big bore kit and I've found this one on eBay item number 130949704487 can anyone tell me if this will fit on my 2007 RMR 125? And if so what piston type do I need flat top or raised? Any help will be most appreciated and I already know this wont make much difference to my bike but want to do it anyway :) added image of the ebay 150cc bore kit
