RIDING THE 2024 BETA 390RR RACE EDITION: THE WRAP

With all the joy surrounding the brand new Beta 450RX motocross bike, you’d assume that Beta is a model new firm that simply found out learn how to make bikes. While a shocked motocross/Supercross media is attempting to determine learn how to pronounce the identify of the corporate, off-road riders aren’t stunned in any respect. We’ve identified that Beta builds nice dust bikes for a very long time. This week we received to trip the 2024 390RR Race Edition, which–no shock to us–is perhaps one of many best four-stroke path bikes out there.

Pete Murray on the 2024 Beta 390RR Race version.

Motocross guys hear up: Beta (pronounced Bay-Duh) has 4 completely different off-road four-strokes constructed on the identical platform: the 350RR, 390RR, 430RR and 480RR. All of these fashions can be found in three completely different configurations: commonplace, Race Edition and dual-sport. So there are 12 completely different four-strokes constructed on the identical fundamental platform, and regardless that the brand new 450 has a unique body and new engine instances, we are able to see it has extra similarities than variations. They all have completely different missions, however Beta is an organization that is aware of learn how to divide the market and serve micro segments with out reinventing any wheels. Externally, you possibly can’t inform the motors aside on any of Beta’s off-road four-strokes. They have mix-and-match cranks and cylinders that consequence within the completely different displacements. The 350 and the 390 have the identical bore, however the 390 bike has a stroke that’s 6mm longer (63.4mm). They even have completely different mapping. Feature for function, a Beta off-road bike stacks up nicely towards something from Austria or japan. The clutch is hydraulic, the brakes are the most recent Nissins, they’ve externally switchable maps and traction management.

The Beta 390RR Race Edition sells for $11,099.

The purpose we love the 390RR Race Edition a lot begins with the truth that it’s the premium configuration. The Race Edition has upgraded the suspension and different extras like handguards and a few bling. The fork on the RE is basically the identical one which comes on the brand new RX; a closed cartridge KYB. It’s arrange far more softly for off-road driving. The commonplace 390RR sells for $10,599 and the Race version is $11,099.
The 390 motor is vigorous and highly effective. It has glorious low finish response and nice top-end over rev. It doesn’t, nonetheless, have an enormous motocross hit. When you need to go sooner, you simply rev it greater. Smallish four-stroke motors (that means below 450cc) have a method of feeling a lot lighter and extra agile than they are surely. Part of that’s in all probability the gyroscopic results of extra crank mass, however extra might be as a result of your mind’s tendency to affiliate large energy with large weight. Whatever the rationale, the 390 appears like a 250F however has extra low finish and a for much longer vary of usable energy.


This isn’t to say that the Beta 350 is simply too sluggish and the larger ones are too huge. They all have their very own personalities. We’ve mentioned that many instances, however we by no means received the possibility to check all 4 again to again till final week. Rondey Smith introduced us all 4 bikes and we discovered that every one has a particular sort of terrain the place it out performs the others. Stay tuned for that story and take a look at the May, 2024 Print version of Dirt Bike for the complete take a look at of the Beta 390RR Race Edition.
