     long time ago.........
 had a chain snap on an mbx 125 snagged on my nice alloy swing arm and near on pulled it off.
 
 mort standard st2 sprockets are 15 front and 42 back
 would'nt mind trying the smaller front, but how much difference will this make to an st2 top end??
 
 has anyone out there done this on an st2?
