Hi, I have a 2011 (60 plate) 450 EXC Factory edition. I have been using it for Green lanes & some pay n play days. Now I want to SM it? The gearing is currently 13T on the front & 50T on the rear (what should this change too ?) I know the SM wheels will be 17" but what width would I need ? What tyre size ? Is there anything else that would need to change ? Would I need a new front calliper or just an adapter for the current calliper ?

All help & comments much appreciated, Thanks in advance,

Mark
