RK Drive Chain

Upgrade your motorcycle's performance with our comprehensive range of high-performance drive chains, engineered by RK EXCEL to meet the rigorous demands of street, off-road, and professional racing environments. Whether you are maintaining a vintage classic, a daily commuter, or a high-horsepower track machine, these chains provide the ultimate blend of durability, efficiency, and strength.

Our collection features advanced sealing technologies designed to maximize chain life while minimizing horsepower loss. From traditional O-rings made of Nitrite Butadiene to proprietary Ultra-Thin U-Rings and UW-Rings, these seals are engineered to lock in lubrication and reduce friction. The specialized racing series incorporates MotoGP and FIM Suzuka 8 Hour Endurance technology, proven to deliver superior performance under extreme stress.

Premium Construction and Engineering

Each chain is manufactured using high-quality materials such as carbon alloy steel, heat-treated and shot-peened for maximum tensile strength. Many models utilize solid bush construction and are pre-stressed and pre-stretched to ensure minimal elongation and consistent performance throughout the life of the chain. For vintage enthusiasts, we offer narrow-clearance designs specifically tailored for classic British and Japanese motorcycles, allowing for modern sealed-chain protection in tight configurations.

Technical Specifications and Features:

• Wide Performance Range: Tensile strengths ranging from 4,540 lbs for lightweight applications up to over 10,430 lbs for heavy-duty endurance.
• Versatile Applications: Suitable for engines ranging from 150cc up to 1400cc, supporting power outputs from 25 HP to over 265 HP.
• Advanced Sealing: Options include O-ring, U-ring, UW-ring, and XW-ring technologies to balance weight and durability.
• Race-Ready Design: Lightweight professional racing options developed in collaboration with World Superbike teams to ensure optimal power delivery.
• Vintage Compatibility: Specialized narrow-width chains designed for OEM replacement on vintage motorcycles from the 1970s through the 1990s.
