Beta has updated its long running trail model the Alp 4.0 for 2018.

Beta’s new Euro 4 compliant version of its Alp 4.0 has a host of updates aimed at reducing emissions but also chassis changes to improve handling and control.

Changes to the Beta Alp’s chassis and handling include a front Nissin brake caliper, for improved feel and power. The rear brake caliper now has a smaller piston to boost its performance.

A new engine control unit with OBD (On-Board Diagnostics) has been introduced (enabling the collection of general diagnostic data), as well as a new digital instrument panel.

The front suspension settings have been updated too to improve feel and comfort.

The new single-beam frame with double cradle under tubes and lighter rear swingarm make the bike more agile, manoeuvrable and easier to ride, Beta claims.

With its revamped look and technical improvements, the new Alp 4.0 retains all of the key features which have long made it a trail-friendly success for Beta.

Suited well to tracks and trails, the Alp is also a great urban commuter bike. All this comes with low running costs which compare very favourably with other specialized off-road models.

The 2018 Alp 4.0 comes in two new colours (black or white) which combine with the red frame to make it even more eye-catching.
