The 2027 Beta RS lineup is the street-legal version of Beta’s RR X-Pro high-performance trail bikes, offered with 350, 390, 430, and 500 engines. All four RSes share one chassis, so every 2027 update applies across the range. Those updates come from the X-Pro, and they bring the RS closer to its off-road sibling, with a different fork, a revised shock, frame changes, and engine durability upgrades. Prices are unchanged from 2026, starting at $12,390 MSRP for the 350 RS. The engines carry over, from the free-revving 350 to the muscular 500, which shares its 478cc single with the RR 480.
For 2027, Beta closed most of the gap between its dual-sport and its enduro bike. Last year’s RSes made do with an open-cartridge fork and steel exhaust valves. Now they have the X-Pro’s ZF Sach SHC fork, titanium valvetrain, revised shock, and frame updates, along with the mirrors, lighting, and GPS that let you legally ride the pavement between trails. The RS lineup remains a step behind the X-Pro on electronics, as the dual-sport bikes don’t get the quickshifter or launch control. Getting down to the hardware that matters most off-road, the RS is now nearly an X-Pro with a license plate, at the same price as last year.
The RS line now uses the Sachs SHC fork from the RR X-Pro. The 2026 RSes ran a 48mm Sachs open-cartridge fork. SHC stands for Separate Hydraulic Chamber, and the 48mm fork splits the work between its legs, with a single spring in the right leg and the damping in the left. Beta says the asymmetrical layout saves about a half pound compared with a conventional fork. For 2027, the internal valving puts more emphasis on initial plushness and bump absorption. The fork is adjustable for spring preload, compression damping, and rebound damping, and it has 11.6 inches of travel.
The Sachs shock gets a redesigned damper and tool-free adjustment. The new damper does a better job of separating the high-speed and low-speed circuits, and the shock is tuned to complement the SHC fork. External adjustments can now be made by hand, with no tools needed. The shock is adjustable for rebound damping and high- and low-speed compression damping, along with spring-preload. Rear wheel travel is 11.4 inches.
The chromoly steel double-cradle frame is new to the RS lineup, with micro-cast headstay and footpeg mounts. The cast pieces are intended to add strength and rigidity. Seat height drops 0.2 inches from last year to 36.6 inches, which puts the seat 0.8 inches lower than the 2027 RR Race models. Ground clearance goes up 0.2 inches to 12.4 inches, and the wheelbase is unchanged at 58.7 inches.
Titanium valves now sit on both the intake and exhaust sides. The 2026 RSes paired titanium intake valves with steel exhaust valves. The 2027 valves also get a revised finish, which is intended to make them more durable and reliable under hard use.
The timing chain tensioner is now purely mechanical, ditching its hydraulic component. It uses a newly calibrated spring, and Beta says the change reduces internal friction, smooths engine operation, and makes starting more consistent whether the engine is hot or cold. Beta first ran this tensioner on its 2026 motocross and cross-country racers. The rear airbox boot is also redesigned, with the goal of steadier airflow and better overall power delivery.
The chain guide and front sprocket guard are tougher. The heavy-duty chain guide has a reinforced structure built to shrug off mud, rocks, and hits from ruts and logs. Its straighter, stronger shape is intended to keep the final drive stable, prevent thrown chains, and protect the swingarm. Up front, the redesigned sprocket guard covers more area and resists impacts better, and Beta says it meets racing safety regulations.
Both of the rider’s hands get something new: softer grips. The new grips are supposed to absorb more trail vibration, reducing fatigue and arm pump.
Prices for the 2027 Beta RS lineup stay at 2026 levels. The 350 RS is $12,390 MSRP, the 390 RS is $12,490, the 430 RS is $12,590, and the 500 RS is $12,690. The RS models arrive at US dealers in December with a two-year limited warranty with no mileage restriction.
Benda motorcycles are beginning to make a ripple on US shores with four intriguing and competitive models, courtesy of its partnership with Keeway Group. We were impressed with the Napoleonbob 500 and have now gotten our gloves on the persuasive, entry-level 2026 Benda Chinchilla 300, with its modest MSRP of $4999. It would be difficult to design a more welcoming entry-level cruiser than this easy-handling, visually appealing boulevard bobber. Editor Don Williams and Associate Editor Kelly Callan discuss the Benda Chinchilla 300 and how it actually rode for them.
