I used the importing a bike thread(sticky) as a reference but still I am wondering about extra stuff like a pipe. I am looking to purchase a new bike and I have the opportunity to make a few changes to the bike. I can change out the pipe which was non-stock but was still produced by the factory that produced the bike for another pipe and I am also considering a windscreen addition. As you may have guessed this is more of sport/touring bike so please don't hold that against me ,as I get older my riding position seems to be slowly working towards a reclining old man position . My brother is out there and I am looking to maybe catch up with him for a ride (he's on a cbr 600) but I could do without bug protein, hence the better screen. So does anybody no what happens with duty etc with these "possibly extra" items or could they just be included in the cost of the new bike? I am thinking if you have the extra money that it might be worth it to get those items right then and there if they are included in the cost of the bike.
