Storm 250 sprocket question

Well, I've put almost 100 miles on the Storm and love it!! It didn't take long though to notice the gearing (especially 1st gear) is too high of a ratio for comfortable street riding. I checked my bike tonight and the factory gearing is 17 tooth countersprocket combined with a 46 tooth rear sprocket.

Others on this forum have stated this sprocket is a direct bolt-on but I wanted to check as my current sprocket has only 4 holes while the suggested sprocket has six holes.

Here's a pic of my current sprocket: Name: IMG_20160425_213911.jpg

As you can see there are 4 holes 90 degrees apart. I suspect two of the holes just wouldn't be used and just the 4 holes 90 degrees apart would line up with the factory hole locations. If anyone can weigh in on this I would appreciate your time.

I know there's a fine line between having enough of a gear ratio for comfortable off-road riding to maintain while being able to maintain speeds on the street without excessive engine rpms. I was thinking a reduction in teeth from 46 to 42 that would give 9.5% increase in speed is a reasonable compromise as I'll be street riding at least 60-70% of the time, thoughts?
