I dont give nods, because im only on a 125 and i dont think i really have the right to yet
Ive got quite a few nods though, and i always nod back.
I dont nod at mopeds or massive shiny cruisers. They are different breeds of bikers...
I wouldnt ever overtake a faster bike. Like today there was this brand new 09 plate ninja that i was behind and it was going so slowwwwwwwwwww, i wanted to overtake it, but cmon its a 100bhp bike, and mines 10bhp. Didnt really seem right.
