AJS Highway Star 125


AJS Highway Star 125
Whether you’re cruising the boulevards, winding your way through country lanes or commuting into town, the Highway Star will make your journey a blast. This bike has a presence on the road like no other 125. It has been styled to be on trend with its turbine wheels, upside down front shocks and twin shot-gun exhaust mufflers.
The low seat height makes this motorcycle easy to handle. The slightly forward, anti-vibration footrests and ergonomically positioned alloy handlebars ensure a comfortable ride, even on the longest journeys.
We’ve added stainless steel fasteners and deep chrome plating for that extra touch of quality.
