2021 Beta RR-S Dual-Sport Series First Look: 10 Quick Facts
There are four motorcycles in the 2021 Beta RR-S dual-sport lineup. This is the same lineup as last year, and there has been no change. As Beta is an Italian boutique brand that still establishes itself in the United States, let’s take a look at the highlights and the difference between the four flavors of the 2021 Beta RR-S dual sport bikes.
1. The frames are identical on all four Beta RR-S 2021 models. You get a fully adjustable Sachs ZF suspension at both ends, with a double cradle chromoly frame. The wheels are Excel Takasago and FIM-approved eco-friendly Michelin Enduro Medium tires are used, while Nissin calipers grip the Galfer discs.
2. For different displacements, two engines share the same bore, while two others have identical strokes. The 500 and 300 have the same 60.8mm stroke, with the 500 having a 100mm piston and the 430 using a 95mm piston. The 390 and 350 use the same piston, while they vary the stroke – 63.4mm for the 390, and the 350 has a stroke of 57.4mm. This makes the 390 the least square of the four engines, and the 500 is the squareest.
3. All four models have a dual injector EFI system with a 42mm throttle body.
4. Beta uses different materials for the valves. All four models have titanium intake valves. However, the 500 and 430 have steel exhaust valves, with the 390 and 350 fitted with titanium exhaust valves.
5. The six-speed transmission works with a hydraulically operated clutch.
6. The 2021 Beta 390 RR-S and 350 RR-S weigh two pounds less than the 500 RR-S and 430 RR-S. These are lightweight dual-sport bikes, the 390 and 350 hitting the scale at 256 pounds with the 2.4 gallon fuel tank topped up.
7. Off-road-friendly features include plastic skid plate, hand guards, and flip-up mirrors. Additionally, a Trail Tech Voyager GPS is standard on the 2021 Beta RR-S models. Electric start is standard, with a kickstarter available as an option.
8. Beta has a statutory advantage over its top selling competitors. Due to its low sales volume, the EPA emissions standards that Beta must adhere to are more flexible than those of Japan and Austria. This makes the engine performance of the 2021 Beta RR-S dual sport motorcycle much closer to their off-road counterparts.
9. Without any changes this year, Beta sticks to last year’s prices. Shipments start at the end of September.
