stuart, i have from memory a pair of mag suzuki wheels from a gt185 (the same as fitted to the x5) which in turn was the same as fitted to the x1 and all small suzuki,s, so yes they,ll fit straight on, they come with the disc as well, i also have a caliper here to fit, master cylinder, you might need a speedo drive gear but i may have one, the fork i have is the one needed with the lugs cast in them to accept the disc, its a simple swap but you will have to strip one fork leg apart to change the fork lowers over, other than that its easy, and beleive me , one hell of a difference in braking power....worlds apart ! all parts are in ready to fit condition as they were going on to my gp125 but i bought a complete donor bike and changed my drums etc over to that and sold it again, hence no longer needing these, £150 plus p&p stuart... oh and the 125 conversion !! well worth it as i,m on the heavy side but if your light then dont bother, cheers jon
