Don't skim what I wrote so you won't miss my point. I don't know if 300 spec tire comes with sticky compound or not. I'm trying to compare between orange vs. orange, not orange with apple, so... Well...I was talking about the same compound...of course, there're differences between sticky and non-sticky compound and weights differences in drag racing. I'm not too familiar with drag racing or what they use. But I'm pretty sure that they have regular or slightly wider tires to save weight and the rest of the traction is helped by wheelie bar, what dya all think? My logic is (based on the same tire compound) on drag racing (eventhough I didn't purposefully have this conversation with drag racing in mind) and I want to counter-argue your statement based on drag racing situation since you brought it up: For instance: 1. First "X" bike with with 300hp, wider "T" rear-wheel, an "L" material stretched swing arm, and equipped with "Z" rear 300 specs tire. 2. Second "X" bike with the "X" OEM hp, and with "T" OEM spec rear-wheel, an "L" material OEM specs swing arm, and equipped with "Z" rear OEM spec tire. 3. An "S" pilot rides both bikes on the same ground, ground temperature, riding gears, and wind resistance. I use the example with the most objectivity in mind that I can think of. I've never tested it and (I MAY BE WRONG) but, the less weight of the second bike can't justify the twice hp of acceleration in comparison with the first bike. That's what I had in mind after reading your respond. My question: on what ground that you call me "wrong"?
