A wee tip for magnetic tank bags...
 

I recently bought a magnetic tank bag for the "R" which works a treat, however after i lay it on the ground, the magnets were strong enough to pick up wee, iron rich stones so, when i put the bag back on the tank they proceeded to scratch my tank to bits! Gutted! If anyone elses uses these bags just be careful you dont wreck your tank :hahaha[1]:
