2024 390–430cc Four-Stroke Enduro Bikes To Buy

2024 Beta 390 RR

According to Beta, its 390 RR is one of the bestselling four-stroke off-road motorcycles in the United States. (Beta/)

First up is the Beta 390 RR. This and other standard-model off-road bikes in the Italian manufacturer’s lineup feature a host of updates for 2024 such as lighter fork internals, a differently shaped seat with softer foam, new front brake hose, and fresh graphics. Engine is a fuel-injected liquid-cooled DOHC four-stroke 386cc single-cylinder with a six-speed transmission. Traction control comes standard and is said to have been improved for MY24. Suspension is one of the biggest differences between the 390 RR and its Race Edition counterpart, the former spec’d with a ZF Sachs 48mm open-cartridge coil-spring fork and ZF Sachs shock.

Stepping it up in price and suspension performance, we have the 390 RR Race Edition. It costs $500 more than the 390 RR, and uses a KYB Air-Oil Separate (AOS) 48mm closed-cartridge coil-spring fork and KYB shock. Other upgrades on the 390 RR Race Edition include black anodized footpegs with steel pins, an aluminum/steel hybrid rear sprocket, a red anodized quick-release axle pull, and hand guards.

2024 Beta 430 RR

There’s a $500 price difference between the 430 RR (pictured) and 430 RR Race Edition. (Beta/)

Beta’s press materials mention the 430 RR is the “wild one of the bunch” with a higher-revving and motocross-bike-like engine character. This Italian machine spun the drum on our in-house Dynojet 250i rear-wheel dynamometer recently, where it cranked out 43.5 hp at 10,300 rpm and 31.0 lb.-ft. of torque at 6,500 rpm. Maxxis MaxxEnduro are wrapped around Excel rims. Further empirical data the Dirt Rider crew gathered on this motorcycle are that it weighs 262 pounds on our automotive scales and has a seat height of 37.1 inches.

2024 Beta 430 RR Race Edition

Being the largest-displacement up-spec option in this list, the 430 RR Race Edition carries the highest suggested retail price. (Beta/)

There are many shared parts between the 430 RR and 430 RR Race Edition, some of the most notable being a fuel-injected liquid-cooled DOHC 431cc four-stroke engine, six-speed gearbox, 42mm throttle body, and double cradle chromoly steel frame. The biggest selling point of the up-spec version is its KYB Air-Oil Separate (AOS) 48mm closed-cartridge coil-spring fork and KYB shock, which have a higher performance ceiling than the ZF Sachs components spec’d on the standard model. Trick bits throughout and a racing-inspired appearance sweeten the deal on the 430 RR Race Edition that much more. Like all of the models in this list, it slows and stops with a Nissin dual-piston front caliper and 260mm floating disc, and Nissin single-piston caliper that clamps onto a 240mm disc.
