If you don’t know much about power-valve adjusters, they preload a spring that controls how quickly the power valve opens. The Beta power valve is adjusted with an Allen key on the left side of the bike. The Beta 300RX power-valve adjuster is very much like the one on the KTM two-strokes, except better. The sun represented a loamy track and the rain was for a slick track. Finally, we took a close look at the button and saw that it had a pictograph of a sun and rain on the switch. We thought it was a leftover part from an off-road model that turned the headlight on and off. At first, we weren’t sure what the button mounted in front of the gas tank did.

By the sounds of it, they are ditching the tall seat in 2022. No problem, we called Beta and they sent us a lower off-road seat. On the other side of the coin, this seat is flat all the way from the rear fender to the tank, and it is too tall for tall riders. There is nothing else like it on the market. The seat has a push-button release on the left side of the bike that takes the seat off in seconds. We will start with the cool factor first. Lots of those brave companies, which at one time included KTM, have risen to the occasion. Most know that their bikes will struggle in the hands of MXA, but they want an unbiased comparison of how their bike stacks up, what parts need to be improved and where they stand. They are afraid of us picking apart the flaws in their “baby.” The ones that are willing to step forward and have their bikes put through the same test regimen as the “Big Seven” want to prove that their bikes can succeed. Many boutique brands avoid letting MXA test their machines. At first glance, we thought, “This is a really cool-looking bike, but it looks like it was made for a giant.” We honestly weren’t expecting much out of the Italian bicicletta sporca. Q: WHAT ARE SOME OF THE KEY FEATURES OF THE 2021 BETA 300RX?Ī: You really need to take a close look at the Beta 300RX to unlock some of its secrets. If they can do that, the sky is the limit. After putting time on the electric-start, two-stroke 300RX, we believe this engine outperforms Beta’s big-name competition.

And, if things go well in Europe, Beta plans to have a factory presence in the 2022 AMA Pro 450 National Motocross Championship. Just as Beta used its 300RR off-road two-stroke as the base for the 300RX motocross bike, Beta will use its 430RR Race Edition off-road bike as the basis for the MXGP motocross bike. The 2021 300RX isn’t the first Beta motocross bikes, but the company shifted their focus to trials and off-road bikes, but this is 1982 Beta MX500 shows that they were serious about motocross before. The 300RX offers a great two-stroke engine package, but it is no match for the power of works 450cc four-strokes.

Since Beta only makes one motocross bike (the 300RX two-stroke) out of 18 off-road models, you might be thinking they would race the 300RX in the MXGPs. For 2021, Beta kicked into high gear, signing off-road ace Jonny Walker in Europe and starting a factory MXGP motocross team with Jeremy Van Horebeek at the controls. The Italian company, which has been around since 1905, can’t be faulted for focusing on what was working, and that was off-road and trials bikes. The 2021 Beta 300RX is the first motocross bike that Beta has produced in close to half a century. Q: FIRST AND FOREMOST, IS THE 2021 BETA 300RX BETTER THAN THE 2020 MODEL?Ī: Yes! Only because there was no 2020 Beta 300RX. THE GEAR: Jersey: Fly Racing Evolution DST, Pants: Fly Racing Evolution DST, Helmet: Fly Racing F2, Goggles: EKS Brand Flat Out, Boots: Gaerne SG-12.
