The Kenda K774 IBEX 120/90-19 Rear Tyre is a high-performance soft-terrain tyre built for extreme enduro and hard enduro riders who demand relentless traction, flexibility, and grip. Engineered with a super-soft gummy compound and unique carcass design, the IBEX grips like a trials tyre while holding up to enduro punishment — making it ideal for slippery rocks, steep climbs, logs, and technical terrain.
✅ This is a wide-profile, soft-compound rear tyre developed for extreme off-road and hard enduro riding — ideal for electric motos like the Sur-Ron Ultra Bee (19" mod), Storm Bee, and 250–450cc enduro builds needing maximum rear wheel traction.
✅ Super Soft Gummy Compound: Ultra-flexible rubber bites into rocks, logs, and roots — providing trials-like grip in technical sections.
✅ Ultra-Flexible Carcass: Designed to conform to terrain for traction in low-speed, high-torque situations without bouncing or deflecting.
✅ Deep Tread Blocks: Large, widely spaced knobs maintain traction and prevent mud buildup in soft and wet terrain.
✅ Extreme Off-Road Performance: Purpose-built for hard enduro, extreme climbs, and slippery conditions.
✅ Excellent Low-Pressure Control: Performs exceptionally well at low PSI for maximum footprint and traction.
✅ Bias-Ply Construction: Offers durability with flexibility — essential for crawling over rough terrain without tearing lugs.
✅ Hard Enduro & Technical Trail: Excels in extreme off-road conditions where precision grip matters most.
✅ E-Moto Traction Builds: Matches the torque of high-power electric dirt bikes for unbeatable traction.
✅ Slippery / Technical Terrain: Grips confidently on rocks, roots, and loose climbs where other tyres spin out.
