What reviewers say

Road tests praise the lively triple engine, easy low-speed manners and generous equipment. Both found the soft suspension and modest brakes less convincing when ridden hard. Visordown found day-long comfort acceptable; CycleNews's two-hour test found the riding position small for its taller rider and questioned value beside the Trident 800.
