Hi All. I have just brought home my Honda XR 400 and would love any advice/tips about maintenance etc. I read many, many reviews about this bike before buying and everyone just talks about how reliable they are. Also what aftermarket exhaust is best to put on? I'm from the U.K. so I wonder if there are many others living here? I know these are very popular in America. Nice to meet you all and thanks in advance for any help people might be able to give. Sam.
