300 RR X-Pro 2-Stroke
The Beta 300 RR X-Pro 2-Stroke is built for riders who want serious enduro performance without giving up the versatility and rideability that make a great trail bike. Its 292.6cc liquid-cooled two-stroke engine combines Beta's Progressive Valve (BPV) power valve system and counter balancer to deliver strong, responsive power while keeping the engine manageable through technical terrain. The six-speed transmission gives you the gearing range to move from tight singletrack to faster open trails, while electronic oil injection and electric start keep the bike simple and convenient to live with. The X-Pro's updated chassis features a larger 22mm rear axle, an updated front brake caliper, larger engine main bearings, and a revised second gear for 2026, improving durability, shifting, and overall handling. At 228 lbs dry with a 36.4-inch seat height, 21"/18" wheels, and 11.6" of front and 11.4" of rear suspension travel, the 300 RR X-Pro has the lightweight feel and ground clearance to attack technical terrain while remaining composed when the trail opens up. Add adjustable Sachs suspension, Brembo-style braking hardware, a 2.5-gallon fuel tank, and Beta's proven two-stroke platform, and the 300 RR X-Pro delivers the perfect balance of power, control, and all-around enduro capability.
