Chains are USUALLY longer than you need.
Until you actually measure the correct chain length for your bike, you really don't know what is correct.
Just because it came with 116 from the factory doesn't mean it's the correct length. DO you think they'd bother removing 2 links if the RDER had enough take up? They might on a high enf bike, but generally they're more concerned about speedy assembly. That's why you see retainer type bearings often used.
