Absolutely. He won't get there as fast but terminal speed is independent of mass.

yes if its the same bike. redline is 15500 for an r6 no matter who's on that bike it will be doing the same speed at 15500 rpm;s. it may take a fat guy longer to acheive redline but the speed at redline will be the same.

maybe that's were I'm getting confussed - speed of wheel vs speed of bike (my head hurts now )

No, you're just confused. Mass has no relation to terminal speed.

yes but if it is reducing the speed it is also reducing the rpms...

all sportbikes are built with enough power to deliver the bike to its redline in 6th gear. so its not like its hard to achieve it. so no matter what the resistance is, if the bike hits 15500 it will be the same speed as if there were no resistance at the same rpm.

Re: Gearing Calculator Tool

ok then will a bike go faster with more horspower even though the rpm doesn't change?

You are neglecting tire slip. It is a real thing.

it will accelerate quicker but unless you change the gearing ratio the rev limiter will kick in at the same top speed. thats why for a drag bike if they put like nitrous and **** on it they will gear the bike down for a higher top speed.

i have no idea what youre talking about. a tire is not slipping when its maintaining a speed.

Actually it is. At high speeds a tire is slightly slipping as the friction is not enough to completely overcome the wind resistance.

Re: Gearing Calculator Tool

so if I put something like a turbo on my bike and hit top speed, I could reach the same top speed eventually if I have a long enough road?

As long as the bike initially had enough power to make it to redline, which sdfkillz is claiming all sportbikes do.

Re: Gearing Calculator Tool

I agree that if the motor is turning X number RPMs the rear wheel has to be turning the Y number of RPMs, but it's definitly weird to think about
