Mods are a preference and what one rider thinks is absolutely necessary another thinks it s silly. After 50k kms on our current trip I will say that basic protection / crashbars is a given and what ever you need to get the bike comfortable. Little pains become very big pains over a long distance of day after day riding. Spend less and ride longer is my advice.
VERY IMPORTANT you need to take a gasket for the stator cover, right side of the engine. Stators fail on our bikes at around 50k kms and without a new gasket you are potentially very SOL.
