Freenduro tested the X-GRIP King Kong STICKY rear tire on a Beta 250 RR X-Pro 2026, with an X-GRIP SSE-2 foam. The test mainly highlights a very specialized use, centered on extreme crossing, descents, roots and rocks, with a clear logic: gain in motor skills where a more conventional enduro tire quickly reaches its limits.

A tire designed for extreme crossing

Freenduro's test presents the X-GRIP King Kong STICKY as an all-hardened enduro rear tire. The very flexible carcass, the soft rubber and the strong deformation by hand are described as the signs of a model designed to embrace the terrain at low speed rather than to ride fast or for long on hard tracks.

The assembly was carried out on a Beta 250 RR X-Pro 2026, with the X-GRIP SSE-2 foam. Freenduro points out that this combination facilitates installation, despite the need for a double gripster to secure the mount on the rim.

• Assembly considered easy despite the extreme flexibility of the tire
• Double gripster presented as indispensable
• Use announced as reserved for pure crossing

Motor skills and control on slippery terrain

The heart of the test is on the behavior on off-road terrain: walking, rolling stones, roots and mud. Freenduro reports a clearly superior motor skills to that of a classic enduro tire, especially during restarts from a stop, technical climbs and steep descents.

The very open profile and the V-shaped design are given as assets to maintain lateral grip in downhill and limit rear slipping. On descent, the tire would also provide more reassuring grip on unstable surfaces, while maintaining the ability to regain traction as soon as braking relaxes.

• Good behavior in sloughs and on virgin tracks
• Restart possible when stopped in a gravel area
• Retention found convincing in descent

The limits of a very typical hard enduro tire

Freenduro insists on the exclusive nature of this tire: it is not presented as a relevant choice for classic enduro, fast links or hard surfaces. At high speed, the very flexible carcass blurs precision and makes the rear more mobile on its supports.

The test also shows a rapid wear of the cleat edges on the rock, even if no tearing or tearing has been observed over about 11 hours of riding. The tire is therefore described as a crossing tool assuming a clear compromise between maximum grip and longevity.

• Reduced precision beyond the appearance of crossing
• Wear and tear of the edges marked quickly
• No tearing reported after about 11 am

Price quotation and positioning

Freenduro mentions a price of €114.90 for the STICKY version and €99.90 for the MEDIUM version. These amounts appear in the context of the article and must be kept as rates collected by the media, without extrapolation to other markets.

In the end, the interest of the King Kong STICKY depends mainly on the terrain and the riding program. For a rider regularly confronted with mud, rocks, wet roots and broken slopes, the test positions it as a seasonal mount to reserve for the most demanding conditions.

• STICKY rate quoted at €114.90
• MEDIUM rate quoted at €99.90
• Interest especially in seasonal or specialized use

Freenduro's test describes the X-GRIP King Kong STICKY as a very effective rear tire as soon as the terrain becomes hostile, but clearly too specialized for versatile use. Its main advantage remains marked mobility on hard enduro, at the price of less precise behavior on the fast and wear that makes it necessary to reserve it for the most demanding rides.
