Beta Alp 4.0 2025

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.

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

BMW F 450 GS 2026

BMW F 450 GS 2026

The BMW F 450 GS is a surprisingly mature A2-category adventure bike. Its 420cc twin cylinder produces plenty of grunt on public roads, its low weight keeps handling pleasantly light even with a passenger, and the adjustable suspension provides clear feedback whilst maintaining a decent level of comfort. Two slender riders can travel comfortably on it with luggage, provided the limited payload and narrow pillion seat suit the riders. On long journeys, the only moderate wind protection and the lack of cruise control become more noticeable; at higher motorway speeds, revs, vibrations and fuel consumption increase. Those not expecting a luxury cruiser will find an accessible, economical and agile touring motorbike that is capable of far more than its 48 Horsepower would suggest.
