My KPX 250 is new and has about 350 miles on it. It has stock gearing and sprockets. Today I wanted to get some details on engine and rpm.

I am 6'1", 180 lbs, no wind and about 84 degrees.

Here is the mph at 5000 rpm in each gear.

1st - 12-13 mph
2nd- 19-20 mph
3rd- 29-30 mph
4th- 37-38 mph
5th- 43-45 mph
6th- 47-50 mph

60 mph it was turning 6300-6400 rpm.

Are these numbers close on your stock KPX?

I probably will be looking to lower the teeth on the rear.

Also, my gas mileage is about 81mpg with mostly 35-50mph on back roads.
