X-Grip "King Kong" Rear Tire

Not a real animal, but definitely a beast. With the KING KONG 140/80-18, X-GRIP delivers pure primal power to your rear wheel. Inspired by the strongest of all gorillas, it embodies raw strength, monstrous grip, and total ruthlessness when the trail turns into your enemy.

Engineered for extreme performance, it delivers what others only promise: control, traction, and stability. Perfect for extreme enduro, hard enduro, cross-country, and classic enduro racing.

An ultra-aggressive block design with a distinctive V-knob layout tears through root carpets, rock gardens, and mud pits like it’s breakfasting on bananas. The open tread structure locks relentlessly into loose terrain and nearly cleans itself, even at low speeds. The tread geometry ensures the knobs bite into anything that doesn’t move fast enough.

Whether it’s Erzberg, Romaniacs, or your personal hell ride through the woods, the X-GRIP KING KONG is built to conquer.

Medium

The KING KONG MEDIUM is made for riders who demand long-lasting performance. With its medium-hard rubber compound, it blends confident grip with robust durability, perfect for long stints, classic enduros, and fast cross-country stages, especially on dry or harder ground.

Its firmer carcass delivers noticeably more stability at high speeds, better puncture resistance, and longer life without sacrificing control. A true all-rounder with bite. Not too soft, not too hard – just right. Exactly how it should be.

Ideal for training days, long-distance races, or classic multi-day enduros where durability is just as critical as grip.
The KING KONG MEDIUM shines on both hard and soft terrain, remains composed at high speeds, and delivers outstanding side grip.

For those who want control, mileage, and performance in a single tyre without compromise.
