There are a lot of cool bikes under 2500 bucks,- but the problem is condition- and it is usually not the engine- Tires, brakes. chain and sprockets, shocks etc add up really quick. Personally, I think something like that BMW F650 is about perfect, another one of those rare "do it all" type bikes, but they are spendy, even used. The way city streets are now, some long travel suspension is a big plus-
Gunsmith, I do not know this for a fact-but I always got the impression motorcycle courier bikes tended to be "throw-aways",inexpensive disposable type machines because of the extreme high risk type of riding. Any truth to it?
