Hi folks Newbie here - just bought a wee 2002 XVS125 to go through my test & it's fab. Unfortunately I've just noticed that I've lost the bar end off the throttle grip Can anyone tell me if this is a standard part? I've done some searching for bar caps & 22mm keeps getting mentioned, but I can't find anything on the existing cap that is 22mm! Also the pics of the new caps don't look familiar at all. Can anyone help me out please? Cheers Clydey
