The Starling picks up pace quick, the cornering is balanced and the grip is very impressive. The bike springs into action … with an unmistakeable trait that appears to hold the line exceptionally well.

The stability and pace carried when the trail opened up was staggering, and the traction through loose, roughed-up turns was plentiful

It’s quiet, fast and handles like a dream.
