KONA PROCESS 153 27.5｜A Legendary Enduro Bike Combining Quick Handling with Outstanding Descending Performance

A signature KONA enduro bike built for riders who truly want to enjoy the descents.

The KONA PROCESS 153 27.5 is a full-suspension mountain bike designed with a strong emphasis on descending performance within the PROCESS lineup.

Rather than simply being a smaller-wheeled version of the 29-inch model, its geometry has been carefully optimized specifically for 27.5-inch wheels. The result is an excellent balance of quick handling and confident stability, making the bike especially fun to control through tight corners and technical sections.

With 160mm of front travel, 153mm of rear travel, and a slack 64.5° head angle, the PROCESS 153 provides plenty of confidence when choosing lines through large gaps and rough terrain.

Up front, it is equipped with a RockShox Yari fork, known for its high stiffness and stable performance. At the rear, a RockShox Deluxe Select Plus Trunnion delivers the progressive, supple suspension feel characteristic of the PROCESS platform while helping reduce harsh bottom-outs.

A TRANZ-X RAD+ dropper post also comes standard, giving you plenty of freedom to move around the bike on descents. As 27.5-inch enduro bikes become increasingly rare, this is an excellent choice for riders looking for both agile handling and serious downhill capability.

Among KONA's enduro lineup, the PROCESS 153 stands out as a true classic built with a particularly strong focus on the enjoyment of descending.

The 27.5-inch version is especially appealing for its nimble handling, responding naturally through tight corners and quick direction changes. While 29-inch wheels have become the mainstream choice in recent years, the 27.5-inch format still offers plenty of appeal for riders who want a bike that feels more playful and easier to throw around on the trail.

The combination of the RockShox Yari and 153mm of rear travel provides a reassuring level of control, allowing you to choose your line with confidence even on rough descents. Compared with the PROCESS 134, the additional stability and capability on steep or demanding terrain are clearly noticeable.

This bike is also in excellent overall condition, making it an easy recommendation for anyone looking for a serious 27.5-inch enduro bike—something that has become increasingly difficult to find. For riders who want to make descending the main focus of their mountain biking, the PROCESS 153 remains a very compelling choice.
