i put some of them jap crap ones on mine, been on 2 years with no problems and used hard ? mine were for a honda so i fitted a hornet perch and converted my fluid clutch to cable and a couple of washers for brake lever. have heard some horror stories about some of them since and would pay for crg or pazzo just for piece of mind next time i rebuild the bike. seems to be some are good some are bad but not worth the risk imho
