Hello.

I want to buy a new exhaust system for my Honda 750 NV, where can i buy one in Pattaya ?

I don't think Honda ever officially sold big motorcycles in this country so there is no dealer support structure here.

You're going to have a hard time finding parts in this country.

You might want to just have an exhaust custom made or get on the internet and pay import taxes.

Ask a shop that sells other big bikes, they should hopefully know a someone or somewhere that can help out.
