Beta Alp 4.0 2025

The Alp 4.0 is a real insider tip for the niche of enduro riders. With its cultivated single-cylinder engine, stable suspension and balanced ergonomics, it offers a height of versatility. The Alp can easily cruise at high speeds, is uncomplicated in city traffic and can do more than you would expect on loose off-road terrain. Steep slopes and rally speeds are too much for it, but if you don't want to go at high speeds and extreme special stages, you can also explore moderately difficult terrain with the Alp 4.0 and don't have to do without riding pleasure. Added to this is a favourable purchase price, which makes some imperfections forgivable and leaves money for great touring.

Accessible, unspectacular, yet fun engine

Stable, well-tuned suspension that can also take harder knocks

Good ergonomics, even when stationary

Clean shifting transmission

Enduro bike tyres

Agile handling

Very versatile

Good price-performance ratio

Brakes could be more responsive

Suspension does not respond very finely to small bumps

Deactivated ABS also resets itself when the engine stalls = cumbersome
