Yes its harder to do on cruiser style bikes due to the fact that we are more stretched out. Sportbikes are more compact in length adding to their agility in corners. Think of it as us having a wheelie bar. I am sure you pop the clutch, wring the throttle and pull hard you can make it happen. The smaller the CC the harder… but you want it bad enough it can happen. I grew up around guys with full on HD Fat Boys ….their fun at the time was “walking” it down our dirt road and seeing who could drop the biggest pile of gravel out of their rear fenders. Needless to say THEY are the biggest reason it took me this long to start riding.
Back to your question though… yea think basic physics talking way back 4th or 3rd grade…. you know the whole see-saw demo…..our power distr. is relatively close to the weight center while the front is stretched out ahead of us… requiring more torgue needed to get the front end up. Sport bikes….. well unless your on a stretched “Busa” (retarded IMPO) everything is right on top of the weight center making it no problem to get that front end up.
Yesterday is a memory, tomorrow is a prediction, but today…… is a Bi**h
