Let's face it riding a motorcycle is a gamble; if you enjoy it enough you will take the risks. But if you are smart, you try to reduce your odds of becoming a skid mark on the pavement as much as possible. I wear bright colors, and stay as attentive and defensive as possible. I wear protective gear, and dont drive recklessly. For example, if I see a car about to turn onto the road I am on, I prepare for the worst, I get my hands ready for a possible emergency stop or evasive maneuver, and I make sure that I have power, I will shift down if I have just started in a gear, etc... All these things together are things that help your odds.
The things mentioned above probably do more than anything to increase my odds of avoiding an accident. But I also have
always replaced my stock can with an aftermarket one on every bike I have owned. I am not talking about exhaust that makes your ears bleed, I am talking about reasonably loud exhaust. The #1 reason I do it, is to increase my odds of being seen(noticed) by inattentive motorists.
I used to be on Fire/Rescue for many years and one of my jobs was working on the 'Jaws of Life' (Hurst Tool) team/First Responders Team for motor vehicle accidents (10-55s), so I have probably seen more car/motorcycle accidents than most.(also why I will
never get on a bike without a helmet...
ever) Most times that someone hits a motorcyclist, they say that they did not see him/her (you would not believe the number of times I have heard that). The stock exhaust on most of the bikes that I have owned is quiet enough that you will not hear it in a car at most any speed. If having a louder exhaust (but still within legal limits) makes more people 'notice' that you are there. That increases the chances that you will not end up a
'car launched, meat missile'. So what if it only increases your chances that they notice you by a couple percentage points. That means a slightly better chance that your number will not come up today. And in my book that is a very good thing. You may decide that it is not worth it for a slightly better chances of avoiding an accident... that is your choice. My
