The ETM RTR XL version uses a 96-link chain, while the ETM RTR with a 14-inch rear wheel uses a 92-link chain. Selecting the right chain length at checkout ensures proper fitment and maintains factory drivetrain geometry.\u003c\/p\u003e\n\u003cp\u003eChain and sprockets wear together as a system. Installing mismatched old and new components accelerates wear on both sides and leads to poor chain engagement and inconsistent throttle response.
