I'm happy to see people resurrecting old bikes and riding them! I look at the current cafe bikes as a form over function kinda thing. Frankly I don't understand why anyone would cafe a 350 Honda with the spindly frame and suspension and slooooow motor. But that's me.
The thing that gets me are people cafeing something without improving the handling or the motor. The whole point of a cafe racer is to go faster-less stuff for lighter bike, better handling to get thru the corners. Seeing stock swingarms, shocks and spindly forks, blah blah blah makes me smile and order another beer.
I like the challenge of getting my old bikes to run better faster and handle better. Currently working on a Triumph 750 and a BMW R90. They'll never go as fast or handle as good as my Buell but I don't care.
