Yes doing the precheck it's easier to see the front but just as easy to see when its facing the rider. While topping off I dont really pay attention to the sight glass I look at the fill line inside the bowl though you can easily see the sight glass from the inside of the bowl. While riding anything could happen, having the ability to see your fluid level while riding is just saftey and ease of mind. Imagine not having or not knowing the fuel level while your riding, would never know when you'd need to take the next exit or pull over, same idea for seeing your 2 most important fluids.Who would want to look at their master cylinder sight gauge when riding? That's something you would check when doing a pre-ride walk around which would be much easier to see when facing the front. Also easier to top off that way. Who would sit on the seat to fill the master cylinder?
