no, a longer rake will slow down the steering. If you take it to an extreme and have something that looked like a chopper then the steering becomes like pushing a wheel barrow where leaning does more than turning the bars. Likewise at the other extreme, if you have no rake at all just a straight line up from the wheel to the bars then it will turn on the stop, but if you try and go at speed it will be incredibly twitchy.
Longer rake = more twitchy though?
