Special advisory from OES: Due to the location of the factory exhaust, specifically the position of the exhaust outlet, the swingarm spools cannot be used on the bike while riding. The spools should be used during maintenance only (wheel removal, chain maintenance, bike parking/storage, etc.) Use of the spools while riding will cause melting and deformation of the right side spool due to heat directed from the exhaust system.
An exception to this requirement is in a case where a Ninja 650 or Z650 has an aftermarket exhaust that does not direct concentrated exhaust gas onto the spool in the same way as the factory exhaust system."
