Increases chain life up to 2 times longer than standard O-ring chains. X-rings reduce friction by up to 40% because of smaller contact area. Lightening holes reduce weight whilst dissipating heat without sacrificing strength. Large diameter heavy-duty pins, chromium carbide treated strengthen the chain, reduces fatigue and increases lifespan. Shot peened, heat treated alloy steel side plates give maximum tensile strength and impact load resistance. Available in gold. 120 links. Designed for motocross and enduro use. Replacement master links available. Made in Japan at top-of-the-line facilities. Tensile strength: 37.8kN (8,497.8lbf/in2) OUTER PLATE shape optimizes low weight and strength. LIGHTENED INNER PLATES that don't compromise strength. SOLID BUSHING that lasts longer than others. COLD-FORGED ROLLERS for superior strength. X-RING SEAL for multi-point contact on seal surfaces. OVERSIZED PIN compared to other competitors’ chains.
