I've had a Sprint about a year and love it but....
I took a Street out yesterday and realised that I need one! What a bike!
I had a couple of hours around Blackburn / Rochdale area and loved every minute. Flexible engine with great drive, quick turning, good brakes etc etc.
I've been looking for a 'fun' bike that'll get me out on the local B roads so KTM singles seemed a good place to start. The new 690's are great bikes with nice engines a superb suspension and I was just about hooked until I got to ride the Street.
Only problem is waiting until November for one! Perhaps they'll bring out a version with fully adjustable suspension? That could be perfect...
