| |  New to Motorized Biking - Engine Noise 70cc vs 80cc vs --cc ??
I did a quick search and didn't find a topic specific to this question, so I am wondering what the general thoughts are on engine noise. I understand there are many engines out there with differing levels of ccs, but are the 80cc engines noisy? I would go with a lower cc engine if it made any difference in noise, if noise is any much of an issue to begin with. |

Seems that different engines are noisier than others with not much corolation as to who sold them or what they are claimed to be.
There are a lot of ways to quiet a noisy bicycle engine, all easy and cheap.
