2026 Beta Alp 4.0 Review: 15 Fast Facts on the Dual-Sport Kingpin

Beta revives its iconic Alp name in the U.S. with the 2026 Alp 4.0, a liquid-cooled dual-sport motorcycle designed to carve a niche between budget-friendly commuters and hardcore off-roaders. The Alp 4.0 slots into the red-hot small-bore adventure/dual-sport segment, where it faces off against the Honda CRF300L and KTM 390 Enduro R.

Priced at $6790, the Alp 4.0 undercuts the premium Beta 350 RS by $5600 but lands $1041 above the CRF300L and $741 over the KTM 390 Enduro R, positioning it as a premium player in its class. Beta has ditched the air-cooled Suzuki DR350 engine that powered European Alps for decades, replacing it with a brand-new 348cc liquid-cooled DOHC single.

The new powerplant features a 44mm throttle body, a 6-speed transmission, and Beta’s claim of 35 horsepower at 9500 rpm. Bore and stroke measure 84.5 x 62mm, and the engine is designed in Italy before being manufactured in China by Guangdong Tayo Motorcycle Technology Co., with final assembly in Italy.

The Alp 4.0’s engine delivers a torquey low-end punch, pulling hard from the bottom while revving smoothly to 10,000 rpm. Throttle response is linear but not snappy, with a slight hesitation off idle that smooths out once the bike is in motion.

The 6-speed gearbox is slick, but short-shifting is the way to go for relaxed dual-sporting. The Alp’s chassis is narrow and lightweight, with a low seat height that makes it feel like a trials bike when standing on the pegs.

Ground clearance is 10.6 inches, and the footpegs sit high for off-road dominance. The handlebar’s low bend and optional aftermarket risers help dial in ergonomics, while the seat—long, lockable, and tool-free removable—splits the difference between a dirt bike and an adventure bike. Passenger pegs are standard. Suspension travel is modest but well-tuned for the Alp’s intended use.

The 43mm non-adjustable fork offers 7.3 inches of travel, while the linkage-assisted shock delivers 7.7 inches with spring preload as the only adjustment. Beta offers fork spring-rate upgrades ($250) and five shock spring options ($221) for riders who want to tweak the setup.

For serious riders, a $1390 accessory shock adds rebound damping and spring-preload adjustment. The Alp 4.0’s braking system relies on Bosch ABS, which defaults to Road mode with a long release on loose surfaces.

Offroad mode recalibrates the ABS for better stopping power in dirt, but switching it off requires a clunky process: stop the bike, toggle the mode to Offroad, hold the ABS button until the dash symbol blinks slowly, then release. ABS reactivates automatically when the key is turned off or the kill switch is used, so riders must stall the engine to disable it temporarily.

Off-road riders will appreciate that the ABS works on both wheels, not just the rear. The Alp 4.0’s riding experience is a blend of trials-inspired agility and dual-sport practicality.

On loose surfaces, the bike excels, forgiving low-speed mistakes and offering confidence-inspiring ground clearance. On pavement, the seat’s firmness and the bike’s narrow width make longer rides less comfortable, though the Alp remains manageable for urban commuting.

The front fender’s low mount and the bike’s overall compact dimensions reinforce its dual-sport ethos. Beta’s Alp 4.0 is a compelling entry in the small-bore dual-sport market, offering Italian craftsmanship, a brand-new engine, and a chassis that leans into its trials heritage.

It’s not the cheapest or the most powerful option, but it carves out a unique space for riders who want a premium, capable, and characterful machine.
