====Speed to rpm relationship====

Speed is set by ~~RPM~~. The relationship between speed and ~~RPM~~ is a fixed, linear relationship. It does not change based on rider weight, wind resistance, or anything else. Each time your pistons cycle through one full (four stroke) cycle the crankshaft turns twice. The clutch separates the crankshaft from the transmission's input shaft. When the clutch is engaged, the input shaft gear is turned by the crankshaft gear. As gears are solid things, that ratio is fixed. It will not change as things go faster or if more load is imparted.

The ratios inside the transmission are fixed. You have 6 set ratios - one for each gear. They are metal parts and do not bend, flex or twist; when you turn the input side at one speed, the output side will spin at a fixed speed, matching the ratio of the gears used. If you had a 1:2 (.5) ratio, then for every 2 turns of the input shaft the output shaft would turn once.

Line 10:

The rear sprocket is bolted to the rear wheel. If the rear sprocket turns once, the rear wheel will also turn once.

So, no matter if you're Valentino Rossi or Meatloaf, if you're going the same RPM you'll be doing the same speed. Weight has nothing to do with ~~RPM~~ or speed.
